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?

patriot class 10 32GB microsdhc announced

Patriot has released a Class 10 32GB micro SDHC card.
Newegg is out of stock but has the price as $99.99.
Just thought y'all might want to know.
Edit: Newegg sez its availability will be 1/8/2011

Do our phones support 32GB microSDs? I read somewhere that 32GB didn't work with our Vibrants which was really ****ty but...was what it was.
Can someone either confirm this or deny it? Specifically, do so by testing with a specific 32GB card...

The benefit would probably be in it being able to keep up with HD video recording, and decreased time scanning the microsdhc card when booting up, or mounting or unmounting it.

Yet, the bigger the card and more data would slow down the scanning. Double edge sword.

Maybe. I depends on how many files it has to catalog. I imagine that a 32GB microsd with 10 2.3GB movies would scan much faster than a 8GB card filled with mp3s

Have you noticed that the card makers are going away from what the Class system is supposed to be. Look at the transfer rates of the Class 4 cards now and they are equal or better than some of the class 10 cards. Doesn't make sense to me, but maybe people didn't understand the Class system and its relationship to transfer rates.

So the Class system is supposed to specify a minimum transfer rate, which increases as the Class goes up.
However, it seems that it is applied arbitrarily by different manufacturers.
Check SD card wiki for more information.

Newegg says they are available
Newegg just notified me that the Patriot 32Gb class 10 micro SDHC is now available. Now it is $99.99.

Newegg also has a Wintec Class 10 32GB for 82.49 - it isn't by Patriot, but it comes with a lifetime warranty.

I have a Wintec 16 gig class 10 in my Vibrant.
Works very well, very snappy performance.
I've never figured out a way to test it in the phone, but thru a adapter on my laptop it hovers around 17-18 meg thruput both read and write.
(edit) BTW, I got it at Frys.
It was 38.99$
Nice price.

Patriot LX 32GB Class 10 benchmarked with SD Tools v1.3
(HTC Desire HD + Android v2.2 rooted)
Oh, by the way, about the SD Class system, it only rate the minimum sustained write speed of the card, but not for random writes.

Wow. That's pretty awful if the benchmark is to be believed.

i have a scandisk class 4 32gb , it has a write speed of 4.8 and a read 11.4

Semi-related, I have a patriot 8gb class 10 card that is holding up very well, including quick transfers. Patriot seems to be pretty good stuff, so I'm considering getting a 16 and passing the 8 down to my girlfriend. I don't think I could find a need for 48GB on the phone, except to hold backups for reflashing.

32 GB Class 4 $55.00 from Amazon itself

If you're looking for a decently priced 32GB class 4 Microsd card backed by one of the biggest and most respected retailers in the world, you can do much worse than this:
http://www.amazon.com/Transcend-Class-microSDHC-Memory-TS32GUSDHC4/dp/B004R7P28W/ref=pd_cp_e_1
This is sold by Amazon... not "fulfilled by Amazon" but actually sold by them. So $55.00 buys you the peace of mind of knowing that if there's anything wrong with the card, you can always get your money back. Plus, this is about as cheap as I, personally, have seen legitimate 32GB cards sold for.
Also, buy with Amazon's Super Saver shipping and shipping is free (does take a bit longer, though.)
In any case, this is probably what I'll do when I get around to upgrading my 16GB card for a 32.

I ordered mine last night and can't wait for it to get here!

I bought a Patriot 32gb Class 4 for $39 + 1.99 shipping from Frys.com. It was a weekend only sale and I ordered mine like 30 minutes prior to the sale ending that Sunday night (so I didn't have time to mass post the deal here). I've since received it and it works great. I'm using it in my Acer Iconia A500 tablet instead of my Evo though. You'd think that watching hi-res movies on the larger screen of the A500 would put the read speed of this Class 4 card to the test, but the whole experience has been flawless.
If you're in the market for a 32gb card, I'd keep an eye on the usual websites (Amazon, Buy.com, Newegg, Frys, etc.) because they Class 4 cards are starting to get rather affordable. The Class 10 cards are still a bit too pricey for my wallet.

My understanding is that the read speed on most of these cards is going to be fine. It's the write speed that varies most and which is dependent on the Class rating of the card. I've got a 16GB class 2 card in my Nook Color and there's no lag watching movies.

The read speed varies significantly between the card classes as well. The big question is whether or not the hardware (which typically trails behind the media) can take advantage of a card with faster access/read times. I haven't found a utility that can speed test the external SD card in my Tegra2 based Acer A500 tablet, but in a thread on another Android forum, the Evo hardware was shown to take advantage of the significantly faster read times in Class 6 & 10 cards.
All that being said, how fast a read time does anyone really need? I've never felt the need to date to go faster than Class 4 card in any of my devices, for both read and even write times.

I wouldn't mind faster write times on my Nook Color if only to be able to copy movies on and off faster (on my current card it takes between 3 and 5 minutes per 1.5 GB title.) Other than that, yeah... not much reason. I've made lots of videos on my Evo and never noiticed any issues with write speed on my Class 4 card.

Thats not a micro SD

I've got a class 10 16GB card in my evo. AND I CORRECTLY did speed tests through my computer and through the phone. and with the class then, there was a huge improvement on speeds even while it was installed in the evo. Professionally speaking.. I think they should install class 10 in all mobile phones. :-D it will only go as fast as its slowest connection.

Which class 10 32GB microSD card?

so, which would be the best, most stable class 10 micro sdhc card? i can't seem to find a definitive answer, as everyone seems to complain about the cards not being a "true class 10", etc. there are only a few reviews on newegg,
http://www.newegg.com/Product/Produ... 600006235 600082443&IsNodeId=1&name=Class 10
and amazon, a bunch of people complain about the speed ratings mot being true.
http://www.amazon.com/s/ref=nb_sb_s...32gb+micro+sd+class+10&ie=UTF8&qid=1318260310
which one do you guys have experience with, and would recommend? the kingstons are just out of the question, as i doubt that they'd be worth twice the coin.

It would be nice if you narrow it down to specific cards.
Although there is to note that most people do not need anything past a class 4 which is more than enough to handle day to day transfer between phone and card.
Sandisk seems to be a darkhorse here since they don't really show you a class number and it ranges from 2 - 6 mbps. The best way is to simply test it out with a SD card testing program.

thanks for the response. specifically, i like the PNY and SanDisk, but like you said, sandisk is secretive about their speeds. i don't want to buy, test the speeds, and return if i'm not happy with it. and is class 10 not required for recording HD video on our phones? thanks again

nah, class 10 is not required to record HD video. besides if i remember correctly, the dz only records up to 720p. you should still be fine unless you're shooting a 20 minute video.

There are some reports from people with various issues with Class 10 cards. Its not widespread by any means (plenty of people here seem fine with their Class 10), but it seems that Class 10 have more issues than lower Classes. So some here will recommend Class 4 or 6 (can't remember which) as the highest you should get.
I'd stay far away from PNY if I were you. I've owned 2 PNY products. Not Micro-SD, but an SD card and a USB thumb drive. On the thumb drive, the USB port and memory chip pulled/broke right out of the plastic casing with regular use (not damaged in any way). The thing just looked and felt flimsy. But I needed one in a hurry for a business trip, and I bought what the store had. I figured, its a USB thumb drive, you can get these things for free. How bad can it be? And I was shocked when the thing actually broke apart after a few weeks.
Similarly, the PNY SD card I have split into 2 pieces (along its seams). In both cases (PNY thumb drive and SD card), the memory chip itself still worked fine, and it was just a matter of using some super glue to hold together the plastic casing that failed. But it just displays shoddy and cheap build quality. I own 3 Sandisk Micro-SD cards, and a couple Sandisk SD cards and thumb drives. Never had an issue with any of them, and build quality is much better than PNY.
There is a long thread in accessories with SD recommendations:
http://forum.xda-developers.com/showthread.php?t=1042324

DUDE! I had the same problem with the PNY thumb-drive! It was the attache series I think. Anyways yea stick to well known brands that are consistently rated high, sandisk, kingston, adata, etc. Honestly though, class 6 would probably be the fastest you'd need unless your gonna be taking extremely high quality pictures at a very fast speed lol aka multi-shot. But then again I'm not sure our phone is even up too that anyways lol.

I have an ADATA 16GB Class 10 from newegg. Has given me zero issues. I would imagine this is probably the same for the 32gb version.
Not sure if the 32GB would hold up. I found out that I'm not that big of a packrat on the size of the SDcard, so I went with a 16gb instead of paying more for space I'd never use, or take years to accumulate.
h2testw 1.4 log after testing it out when I received it:
Warning: Only 15786 of 15787 MByte tested.
Writing speed: 15.1 MByte/s
Reading speed: 18.5 MByte/s
It was definitely a step up from the 4GB class 4 kingston I was previously using, which was getting write speeds of around 5-6mb/sec. After moving onto the Adata, I noticed speedier loading in the photo gallery like night and day. It used to take 2-3 seconds to load the gallery, especially if it was a big picture folder. Now it takes literally milliseconds to load the content. Of course, this may just be anecdotal and placebo effect, but my general experience with android and sdcards for the last 3 years is on the line about it.

actually i retract the kingston comment, i think they had problems with 32gb class 10 cards specifically now that i recall...

The Sandisk that came with my phone has the class 4 symbol printed on the card...
I'm thinking of getting a class 4 myself, don't feel like paying almost +100% for class 10. I'll probably get an A-Data, as it gives a decent price per GB. I'm just torn between 16 and 32 GB
As for Kingston, I think the quality of their products went down a lot in the last two years.

Its an old card. Sandisk used to designate Class, but they don't anymore.

If you look through the thread I linked on my previous response, you will see there are some folks that claim more data corruption issues with 32 Gb cards versus smaller capacities. It seems purely anecdotal. But my point is, don't assume.

My adata 32gb class 4 is going strong since august...

sooo... is class 6 good enough for games, apps2sd, recording HD video, etc?

For me I bought this off ebay ( http://www.ebay.com/itm/380405008880?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 ) and it has been working great for me. I loaded it up to about 28Gig and had no trouble. Currently I have 10gig free.

I've got the Sandisk 32gb class 10.
But the one from Samsung seems great.

The SanDisk 64GB MicroSDXC is also fully compatible despite the device being a sdhc device. Apparently the protocol differences lie on code and not on hardware.

Yea according to this article and many other phones on Gingerbread. I suppose there shouldn't be any problem under ICS.

well. that is fantastic.. Maybe when the prices go down in a year i can get that to upgrade my 32gb card.

Is class 10 SD card necessary?

From what I understand I would need the class 10 card if I want to record HD video. If I am not going to record video can I get away with class 4?
Thanks for any help!

You do not need a class 10 to record HD Video, a class 4 does the job perfectly well. I had a 32GB class 4 sandisk and it was fine.

I've heard that for smartphones, Class 10 is even worse than lower classes.
That's because class 10 has fast block reading speeding. The problem is that it comes at a price of slow random access reading. If you want to play high bitrate movies from the SD card, higher class will be better for sure. However for day-to-day usage, lower class might make the phone feel faster.

class 4 is good enough for video recording.
iirc, 1080p video on the note is recorded at a bitrate of around 17mbps or so. convert that from bits to bytes and its something like 2.125mb/s minimum required to record videos at 1080p. so anything higher than a class 2 should be fine for playback and recording (unless you encode at a silly bitrate).
the only time i could see anyone really needing the faster class speed would be if you wanted to take 8mp shots in rapid succession. depending on the colour tone of the image you intend to take, the file size can go up to 3mb. at that point, your photos per second will be limited by the speed of your memory card. ie. class 4 = 1 photo per second, class 6 = 2 photos per second, class 10 = 3 photos per second maximum.

Be careful in stores. Went to best buy last night for SD card. Class 4 cards only in phone section but at class 10 price from camera section. Also shelf had classes mixed up only sorted by gb. So pay attention to what your getting

Whelp, I know that my bullcrap cheapo Lexar "class 10" wont allow me to record to it directly.
Man.. I'm pissed. time to look for a new one.

Hope a Samsung 32GB c10 I am thinking of buying will be ok on a SAMSUNG device...

microSD Class 10
What about if you will move (apps2SD) games like Sentinel (TD game) in the microSD, is it necessary to go for c10?
I'm confused on what to buy, c4 or c10.
Need your help!

For me it is. copying movies from PC to my SD card is just painful on class4.
I see that some good class10 cards can write at 20mb/s (sequential), which is 5 times as fast as my current class4 sandisk (4.1mb/s).
The only thing that is holding me back is the price. Once the price comes down a bit ill definitely grab a c10 kingston 32gb.

What about for games you move to your external sd card? Will performance decrease with a c4? Much better with c10?
What can you say about the Ridata 32gb class 10? Is it any good compared to transcend or kingston or sandisk?

Dont know about games, I doubt c10 will make a difference at all....but dont mark my words
As for brand you should look at the particular model rather than judging by just the brand. For instance the sandisk mobile ultra (class 4) beats many of the other class10 cards

Amazon
I managed to get a class 10 32 gig for about £25. Currently they are very cheap so it might be worth getting it either way.

When I switched from a class4 32GB sandisk to a class10 32GB Lexar, I noticed the smartphone working faster and snappier, probably APP2SD in gingerbread and pictures and videos in the gallery has something to do with that change in response.
In my experience with memory cards and professional equipment, not only we shall choose for class ratings, but also for trusted brands, like sandisk, lexar and transcend.
To sum up, class10 is better than class4, and if the diference in price is not very high, totally worth it, but, there is a lot more difference in daily use between a galaxy note and a HTC Desire.

Class 10 is for marketing, it's totally not needed for smartphone with internal memcard.

You might want to read this thread on why class 4 is better suited for smartphone use.

Sandisk 16/32GB Mobile Ultra
Guys!
What can you say about Sandisk's Mobile Ultra microSD cards? I'm planning to buy this sdcard instead of class10 microsd cards.
Thanks!
