What MicroSD are you using?

Hi, I have been searching on the forum in search of some information on MicroSD cards and came to no avail.
With my HD, it came with a 8GB Class 6 MicroSDHC. I think it needed it to play videos. I can't imagine using it with a slower card.
Now, my TP2 will arrive Monday and I would like to know the following:
1. Brand
2. Size
3. Speed (class)
4. Price
Is it performing well with the video playbacks or have you installed the SD Tuner software available for the HD?
What do you recommend?
Many, many thanks for any replies, comments and help!

Bought a A-Data microSD class 6, 4 GB at a local computer store.
Not the one i was looking for, i wanted the 8GB or 16GB but both where not in stock and the 4GB was less then 10 euros. I will buy a larger one in a few months.
With class 6 my phone isn't slowed down. A few years ago i bought a 2GB mini-SD, but my HTC Vox was slowed down very much. Didn't look to the class/or speed back then.
MicroSD cards based on SLC might be beter them MLC. IMHO i would always take a class 6 or higher card. However class 8 cards are hard to find.

I'm using the 8GB Class 4 card that came with my daughter's Nokia 5800 and it seems fine. Just watched an xdiv episode of Only Fools and Horses on it with no stutter or dropped frames.
I bought a class 6 off Ebay and it should be here on Monday so I can compare then

i'm using sandisk 8g class 2. whatched movies and played music, everything is fine. It only cost me just under tenner.

The performance diference between a class 2 or a class 6 is not that noticeable. However, at the price the cards are, I think it worths always to buy a class 6 card.
I bought a Transcend 8GB class 6 card. It cost me aprox. 20€.
The biggest differences I noticed between a class 2 and 6 card are:
-Taking photos is faster with class 6
-Browsing photos in sdcard is a bit faster also
-Viewing movies sometimes is a bit more smooth.
HastaSSSS

I have a 16GB class 2 Sandisk. I watch movies just fine. I figure with a class 6 i might be able to watch HD videos more smoothly.

Hi guys,
Thanks for all your replies. So from what you guys are telling me, it is always better to pay that little extra for the class 6 MicroSDs. But then again, is it worth investing in a 16GB Class 4 (no Class 6 available except the brand A-Data) or an 8GB Class 6.
16GB is nearly 4 times more expensive than the 8GB and yet it is slower. Shall I just get 2 8GB and hot swap the 2 cards as need be?

I have read about this brand, and what others said was that their Class 6 under performs Sandisk's Class 4 Cards. Do yo notice any differences? How is the performance?
Also, I wouldn't recommend buying these cards off eBay. There are so many, fake cards on there. I know so, because I know mates that sell these cards. I would just buy from a genuine local store and pay a little bit more unless you don't care about performance.
Anyway, my last question.
What brand do you think has the best performance. Yeah, we can find out all the data about these cards on the web but it's nothing like the hands on tests from real users. So, will it be Sandisk, Transend, Toshiba, Kingston or the later A-Data?

Found a pretty review on the Sandisk 16GB C4 MicroSDHC cards. They compared it to the Kingston 8GB C4 MicroSDHC card.
Sandisk seems to be the company that is producing the fastest cards. It out performs Kingston.
But $133, is a bit steep. I think if I am correct a Sandisk 8GB C6 MicroSDHC is only $49.
What do you think?

You won't notice much difference between class 2 and class 6 as the device can only read at a certain speed, which is nearer class 4.
There are some cheap class 2 16gb cards out there, I have them and you only really notice if you install something like sdtuneup, but then again, you wouldn't notice much difference between class4 and class6

SanDisk microSDHC 16 GB Mobile Ultra works fine!
With the enclosed reader it is really fast via USB.

Cheers for the heads up about the TP2's read speed.
I was going to go for a 16GB class 2 but now might hold out for a class 4.
Haven't noticed any speed difference between my 8GB class 4 and 6 cards except that it's possibly slower than my Trinity but that may be due to the crummy TP2 stock ROM...

Please don't get two 8GB's, you will ruin the back cover of the device swapping the cards over all the time

My understanding is that the Class affects write speed, not read speed, so you won't see a difference playing movies on one or the other. You will see a difference in the amount of time it takes to get the movie onto the card (providing you aren't using ActiveSync, which will slow things down way beyond Class2 speeds).
I have a SanDisk Class 2 16 GB card on my Vogue and watch movies just fine with CorePlayer. Maybe a brief stutter once every 5 minutes or so, which I attribute to WinMo doing some other task in the background, not the read speed of the card.
In short, if it doesn't matter to you how long it takes to transfer large files onto the card, go with the least expensive.

Really? How much slower?
Yeah, I think I will go for 16GB for sure. The only thing now is what class. I am hearing 2 things here. I am worried about stutters on watching movies.
Some are saying speed only matters to write and not read.
But then I have read that it does matter, that is why there is a SDTuneUp for the HD.
I really don't want to buy a cheaper Class 2 card and only finding it is not working to my standards. I am pretty fussy about these things.
Any of you needed to install the SDTuneUp registry edit for the TP2? Do we need it? Anyone did any tests?

Check this out.
And this.
Class rating only refers to write speed, even though on the official SD association page it says "transfer speed." What they don't say is that it's transfer speed only one direction.

Hello ajbopp,
Thanks for your additional information. I think not a lot of people actually realise this. I always thought the Class Rating was how you determine transfer speed and not just write speed.
But there must be some ratings for Reading. Some cards are faster than others and that will certainly affect the rate of requiring information from the card, right? Because files are written in blocks and are distributed everywhere (fragmentation), so if the card is faster, then finding the blocks will be quicker, hence a better performance for reading movie files.
Just thinking logically how computer hard disk works. Not sure if that applies to SDHC cards. I also think the speed is also determined by the drive (the hardware reading/writing on the card).
There aren't many information on this. I have been searching around and most information I found was given by the companies that made these cards. Real tests are few and far between. Most websites I visited, tells me only of the write speed as I think that is what is most important to people who uses these cards, such as Photo Fanatics who needs speed for taking high end photos very quickly and for taking HD videos at 30fps. There is less need to know about read speed.
It's so confusing...

Got it yesterday. Thanks for all your help guys!
I finally went for the Transcend 8GB Class 6 Micro SDHC. Cost of only $187 HKD, roughly $23 USD. Didn't end up getting the 16GB as they didn't have any in stock and it costs 3 times the amount.
Without any tests, I just loaded my movies and it played very well. No dropped frames. No tweaks whatsoever.

Hello!
I had a TP with a Micro SD 8GB Class 2 card.
I'm considering buying a new one (lack of space available) and I wonder if I should consider a class 4 or 6...
I use the MicroSD to store software, pictures (camera), music (to listen), and some videos (to watch).
I don't intend to remove the microsd from the TP2 slot (have to remove the cover) so what I usually do is to connect via USB cable (data instead of AS).
So, transfering data like this will I notice difference with Class 2, 4 or 6?
I'd get a good price with this:
http://www.amazon.com/Kingston-Technology-SDC2-16GB-microSDHC/dp/B001RPD06I
is it good enough or should I buy a Sandisk or perhaps a Class 4 or 6?
Thanks

SanDisk and Kingston are both good manufactures.
Class 4 is faster than class 2 and class 6 is faster than class 4.
But on the other hand: class 4 cards need more power consumption than class 2 cards and class 6 cards need power consumption than class 4.
For this reason I bought 1 x 16gb class 4. That is the compromise of speed and power.

Again, this is only for write speed. I think it's an important distinction to make, especially if you are hoping for better video playback because of a faster card. The class of the card is not likely to have any impact on the device's performance, either video or anything else (other than file saving/writing operations).

so... for my kinda use there is no need for a class 6 right?
do you think a class 2 kingston MicroSD 16GB can be used for what I want?
playback music and some video... storage ... navigation?

[Q] SD class X for heavy 720p recording?

Going on a long long trip and only have room for my Dinc.... Will a class 4 card get the job done or do I need to get a class 6?
Thanx!

That really just matters when copying/writing the initial file and on read times.
For video saving or video playback, it might save you and extra few seconds during the save or load times, but it shouldn't matter at all.
I have a 16GB class 2 card, ran the SD card speed test app, and it came out as a class 4 card.
I notice perfectly fine speeds on my card. I never seem to think to myself, "this thing is damn slow." If you do something like sync 500+ songs to the card at one time, sure it may take a little while to initially find them, but after that there's no wait.
Hope that helps.

I just made a post about class and brand in the accessories section. Take a quick look at that. But class shouldn't really save much time unless you are recording really long videos, the most it will save you is maybe 2 seconds TOPS after finishing video recording. My sandisk 16GB class 2 saved videos in 2.5 seconds or less.

ok, thanks for that info. i was under the impression that the write speed of the card was a limiting factor in bitrate/framerate. Therefore I would get better video quality using a faster SD card. I have seen posts where peeps complain about jerky video @ 720p and the class 2 card is most always the culprit.

Well considering it isn't attempting to write the video as it is recording, class does not apply to this. Framerate/bitrate is controlled by the recording software and the camera itself. SD card just stores the finished product.

More for less, or same for more?
Rather than pony up the extra benjamins for a higher class card, why not get the/a bigger 32 Gb class 2 card, like the one from Verizon?
I have it, it too tests @ class 4, I've had no issues whatsoever.

cool, thank u for that 2 cents.

Well it depends if someone needs faster transfer rates or higher capacity, as well as cost difference. 32gb cards are going for 75 to 90 bucks still being that they are still relatively new, while a 16gb class 10 from kingston is about the same price, maybe even cheaper with transfer rates at least 3 times faster than any class 2. All in preference.

So as far as media playback goes, will I notice much of a difference on class 4 vs class 6 on a 32 GB card? The speed difference is really in file location, not playback right?

Basically, yes.

What speed and/or Class card do you use for your memory card?

Hey
Im sorta "hell bent" on getting a 32GB microSD Class 10 card ( http://forum.xda-developers.com/showthread.php?t=1031312 ) but they are very limited to find. I want a Class 10 because of data transfer and the snapping of pictures/video taking is alot quicker.
I just want to know what class did you get, for what purpose, and what do you use your mobile device most (taking pictures, internet, calling, etc).
Just so everyone knows (just in case):
The Speed Class Rating is the official unit of speed measurement for SD Cards, defined by the SD Association. The Class number represents a multiple of 8 Mbits/s (1 MB/s), and meets the least sustained write speeds for a card in a fragmented state.

Hey,
I was really keen on getting a class 10 32Gb too, but they are very expensive. In then end I opted for a 16Gb class 10 as Play.com had them on offer a month or so ago. I got a sandisk one. Just had a look for a link, but I don't think they have them now.
Guess you could get it anywhere though. I paid £15 including delivery.
I've done a couple of measurements and it's definitely performing at class 10 speeds. I have an HD2 running an Android Gingerbread SD build and the speed has been more than adequate.
My use is mostly internet, texts and calls. I have done some video/photo stuff since getting the card and it's definitely fast enough.
I used to have a class 6 PNY 8Gb one in there and it's a hell of an improvement, especially now I'm on an SD build. The only thing I would say is android takes a fair while to do it's 'preparing SD card' business when I turn the phone on, but no other issues to report. the new card seems to have helped with the hang issues on installing market apps too, which is nice.
Also - did a defrag on it with Mydefrag (beautiful tool!), which seems to have helped too.
Hope that helps!

I still use my stock 8GB card I got with my phone. My main use is pictures and apps. Its a class 2.

I'm currently using 2 32GB Sandisk cards... one is marked class 2, one is marked class 4, but both their average write speeds are pretty similar. They could accurately be marked as class 6.
But really, the class is not important to me. When it comes to choosing a card to use in my phone, I look for cards with quick access times and fast random read and write speeds. Class ratings are really only important when the cards are going to be used in a digital camera or be used as a flash storage drive where you will be transferring large files back and forth.
When it comes to cell phones, a card that can quickly access files and can read/write to many different parts of the card quickly is much more important than a card that can write sequentially fast. You may be able to take large pictures with the camera more quickly with a higher class card, but many cards sacrifice their random access speeds to get that high sequential write speed. This can cause lags and performance loss when running apps or system files off the higher class cards.
The best cards to generally use in cell phones is a class 2 or 4. Many class 6 may perform well, too. There may even be class 10 cards that don't sacrifice that random access speeds. Quality and brand are generally much more important than class to get good access speeds and random read/write speeds.
I really think there needs to be a new rating system for access speeds and random speeds. In general, the lower class cards have better random access speeds, but that's not always the case. There are plenty of class 2 and 4 cards that have terrible random access times, and many class 6 and even 10 that still have great random access. Unfortunately, there's no way to know how a card rates in these areas until you actually test it.
I've always had good results from Sandisk cards... and terrible results from Kingston.
Hopefully, since WP7 requires cards used with it to have good random access speeds, we might start seeing some lines of microSD cards that rate these speeds.
But for now, if you're using the card with wp7, or running android off the card, or running apps or other system files off the card, you will generally have better results with high-quality lower-class cards. I have only been using Class 2 and 4 Sandisk recently. Hopefully a new class and rating system is created for using these cards with smartphones. We are using them more and more for the purpose of internal phone memory... especially windows phone 7, and even with android you see more people making partitions on their cards to use as internal memory to run app and system files. We need a better rating system for cards, cause the current class rating is pretty much meaningless for smartphone purposes.

Defraging a flash based storage device does nothing and actually makes its lifetime smaller.

Great post as in the other thread I may have to go with a Class 4 (as there are even less Class 6) card as it will also lower the price in my budget. Cant have everything...

I got a good deal on a Samsung 16 gb class 2, figured I'd go for it because I don't really use my phone for too much HD recording . However, it consistently benchmarks at class 6 speeds.
Yes, I did vote

No clue, is there a program which can be used to check it in a SGS?

Definitely Sandisk....if getting 32GB, look for model # ending in B35A or B35N. I think that's the one I got. I'll double check tonight and let you know. It was listed as class 2 when I ordered it, but it was marked class 4 when I got it, and it had sequential write speeds equal to class 6 (6MB/Sec). I also have a 32GB with model # ending in A11M... this one was mark class 2, but I think newer ones are also marked class 4. Not sure if the newer ones marked class 4 have better performance than the ones marked class 2, but mine which is marked class 2 could also easily be marked class 6 and be as fast in sequential write speeds as most class 6 of other brands... but the class 2 A11M is not quite as fast as the class 4 B36A that I have in both sequential write/read and random read/write & access times. But like I said, the newer A11Ms marked as class 4 may have better performance than the ones marked class 2, and the performance difference between my 2 32GB Sandisks is not very big.... both are VERY good cards in overall performance.
I got both my cards from provantage, I believe.

Hey zarathustrax, I'm maintaining a microSD benchmark results thread and we have quite a few results now, and it backs up everything you are saying. The 32GB Class2 Sandisk (when it was available) owns everything on random writes. Followed by the 32 Class4 Sandisk.
By comparison, a 32GB Class10 Lexar is benching 350 times slower for random writes than the Sandisk. And yet only offers a doubling of sequential write speed.
Additionally, I maintain an in-phone microSD benchmark thread too. But the results are pretty much cached out by whatever ROM you are running on your phone. So slow cards become much faster, and fast cards become much slower. In the end we found that all cards were performing at around the same speeds. Its only when you changed ROMs would you see a change in in-phone card speed.

Thanks. Im going to read your links now and see if there are model numbers and get some cards (I should have already bought the card before yesterday)
Thanks again stumo5

Damn, no model numbers

Stores that are near me and deliver to me only offer Kingston lol...

Holy ****!
I have found one that has a Sandisk; The only problem is that on the webpage it says that it is a SDSDQM-032G-B35 but the picture shows a 2 written on the card, meaning Class 2. I pretty much refuse going from a Class 10 to a Class 2 and besides the price is 95....
Im going to call and get the model number anyhow....

Kingston 60 bucks
Sandisk 95 bucks
Man how they like to **** consumers in the ass Anyways, he said that what was shown to him was divided by categories and he couldnt tell me the exact model number as it just showed him prices and who supplied it but I rather pay on eBay a Lexar Class 10 at 96 rather than a Sandisk Class 2/4 at 95.
More comparisons: A Sandisk Class 2 32GB at 89 bucks on eBay.
I mean I really have to juggle and ask my self: Is it really worth it? Being on a slight budget, Im not sure.
stumo5 - Has anyone done tests in your microsd exam on TopRAM? I might get them at the end as the prices are just rapist ( ). zarathustrax, the price doesnt justify to me at the end, unless I will notice it.
My main dilema was how pictures were going to be taken as I imagine there will be a lag in picture when I press it and when it is actually taken. Also file transfers and installing/running applications from the SD card. Your explanation was great zarathustrax but Im not sure if its going to be worth the price.
My first smartphone (Nokia E70) I went with Kingston but it surprises me in a way that people talk so bad about Kingston in the flash memory card area.

And I now see on eBay a Sandisk 32GB Class 4 at about 75....More or less.

I'm currently using the 8gb one that came with my Desire Z although I have a class 6 8Gb somewhere that I bought but I haven't felt the need to swap yet for some reason I can't tell a difference

[Q] Xperia PLAY MicroSDHC speed?

I am having an 8GB class 10 Toshiba MicroSDHC with technical reading speed indicated at up to 25mb/s and writing speed up to 20mb/s but I usually can only get slightly more than half of its full speed capability when running a benchmark Is it because I did not perform an initial format for the card or the Play does not support such hi-speed transaction?

It has been proven that the Xperia PLAY and probably other phones as well have problems with Class 10 cards. The problem with Class 10 cards is that, while they have super high speed writing capabilities, there goes a trouble with reading speeds. It has been proven in games in which during gameplay, the games that were tested lagged to the point of unplayability while they are trying to read game data (or SD files, more commonly) from the card.
Users here mostly recommend Class 2 and 4 regardless of the capacity.
PS: I can live with Class 2 microSDHC, so why can't you?

Well, I was attracted by producer's advertisement of their so-called fastest microsdhc in the market and did not know the fact that my PLAY does not handle such speed.
Since I already bought it, do you know if there is any solution now to overcome this problem and utilize the full capability of the card' speed?

honestly, i don't know. first things first when buying new hardware, read and read and read and read and read and read a lot of reviews until you are satisfied. never read company claims because they are just marketing strategies, ALL LIES, rather, read user opinions.
since you bought it already, all i can think of for it to not be wasted is to just buy a card reader for it and use it as a flash memory stick for your laptop or desktop instead. i mean use it like a regular USB flash drive. that's just my opinion though. you really can't stick a Class 10 card on the XPlay. all hell will break loose.
start looking for class 2 or 4 instead.

So sad...I thought I could somehow improve my PLAY performance. Anyway, I think I will use it for my Digital Camera instead and start looking for the class 4 one as your advise.

Class 10 cards are KILLER in a digital Camera. I use one in my Canon Rebel T1i and continuous shooting works so much better and faster with a Class 10 card. Also much smoother video recording if you record in HD.
BTW the best card for this device is the Sandisk 32GB Class 4 card. Buy from a reputable seller as fakes are out there...

I am currently using a Sandisc 32gb Class 4 card and there are slight lags on Modern COmbat 2, my old card was a class 6 16gb card. I saw better performance on the class 6. I am aware of the class 10 issues. My question is I am currently using SD card speed increase software to cahgne the Android cache size from 128kb to 4mb, is this software make a difference? Just curious to get peoples input.

i'd stick to class 2 if i were you, it's slow when writing (but that's already fast for me), but it's fast when reading.. at least no lags when something operates within the card..
and oh, is it true that SanDisk get their cards from random unbranded producers then label them with "SanDisk"? If so, then I won't trust this brand anymore..
what is the best brand then? they say it's only between SanDisk, Kingston, and Transcend. But my sister had problems with Kingston USB Flash drives where they periodically corrupt files and have slow writing/reading speeds and that gives me a negative feedback on the whole company. as for Transcend, i think it's too cheap that the quality might be substandard.
I'm still using the stock card that came with my Play (i don't know but it doesn't have a brand) and it's doing its job pretty well. i'm considering an upgrade soon.

Class 10 cards are KILLER in a digital Camera. I use one in my Canon Rebel T1i and continuous shooting works so much better and faster with a Class 10 card. Also much smoother video recording if you record in HD.
BTW the best card for this device is the Sandisk 32GB Class 4 card. Buy from a reputable seller as fakes are out there...

It is a great information indeed. I am more confident for my next choice of card now.

Problem with high class SDHC cards is that they're good at big files, but suck at small files like game data files on phones.

Class 4&6 are the most versatile for all the various things you might do with the phone.
Also, I've always found SanDisk to be the most reliable.

Need a recommendation on SD card

Hey everyone, I've never purchased one of these for a phone as they've always came with one. Anyway I'm looking for a solid recommendation for a fast 32GB SD card. I have a Tiger Direct local to me so I'll probably try to go their today once I have something to reference.
Thanks

A-data are safe
so are Transcend
Legit SanDisk are good, but they are always twice the price of either of the above

What about Class type? I see people say 4 is fine but then I see others that say either 6 or 10 for access speeds relating to pics and videos.

I will recomnend you buying a class 6 or higher; possibly a class 10. Samsung has it in both so u can purchase it

don't buy anything less than class 6, too slow for a good fast phone experience, specially if you plan to run apps from the SD card

Don't do this. Look here: http://forum.xda-developers.com/showthread.php?p=15269669#post15269669

I use a class 4 32gb sandisk and the speed is fine. Lower class cards are more realiable and the average user cant tell the difference unless you're transferring large files or large quantities of files at once. My class 4 acts like a class 6 but is super reliable.
Id highly recommend a class 4 over a class 10. There's a thread around here if you search that will tell you the benefits of a class 4 and lower class against higher class cards.
Deebo took your bike too?

Just purchased 32GB san disk micro SD from amazon for $37 and it works great. Replaced my old 16GB where there was not enought space to keep my fav music library.

isn't the only thing the class does is gauge the speed of transferring files to and from the sd card, not the actual performance?

Higher class, like another poster said, will give you higher speeds for large file transfers. However, this comes (from testing) at a sacrifice in everyday use of read speeds on everyday smaller files (think gallery, music player, etc). That's basically a short summary of what other XDA members have found from testing. Personally, I picked up a 32GB card from SanDisk off of Amazon and am completely satisfied. You may have a slightly slower time adding all of your files initially, but you most likely won't notice the difference when accessing all those files later on the phone. Look up the card on Amazon and the corresponding reviews and decide for yourself. Hope this helps.

personally, i find those Class 10 to perform better for me.
the time it takes to write/read small files is negligent compared to the amount of time it takes to write/read large files like MP3, MKV, etc
those word documents/excel spreadsheets, pdf, notepad texts, loads up instantly on my Adata 32GB Class 10. and i got 3 of them
1 for music
1 for videos
1 for apps/games/docs/work
so again, that is yet another one of those where the benchmark says one thing, but real life usage shows otherwise

I use a PNY 16GB Class 10.
