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?

Suggestions for 16GB class 4+ microSD card

I'm looking at upgrading the stock 8GB class 2 card that came with the Evo. 32GB are a little pricey still, and I'd like to have a little more storage since I'm upgrading, so I'm looking at 16GB cards. I saw this from Amazon. Decent price too. Any suggestions out there? I'd like something that would be fast enough for if/when the video recording issue gets resolved. I'm not sure about ebay because I've read that people get crappy cards that don't write to said capacity and poor write/read speeds. But if you bought from ebay and it worked out for you, post a link of what you bought!

I recommend this card. It is rated as a class 2, but performs better than most class 6 cards. It has impressive benchmark results and works well in dedicated HD camcorders. Check the link in this thread to Slickdeals for review: http://forum.xda-developers.com/showthread.php?t=715012

Nice find! Benchmark on it basically doubles that of the Sandisk 8GB CL2 that came with my EVO benched @ Write: 2.8MB/S and Read: 6.6MB/S.
In addition, I still have a store credit of $17 from 2007..basically free after rebate. Lol.

Definitely not worth the risk. I've read a lot of mixed reviews from the card only reading 2GB, to constant errors, and eventually failure within weeks/months.

i bought this one:

Which micro sd card do you suggest to buy?

hey
Which card should i buy?
Which class is the internal memory?
Do i need class 10 card?
thnks.

I have a 16 gig class ten and it made no difference on my N1 compared to the stock class 4 card as far as performance goes with apps2sd and the like during operation. It also made no difference transferring files to or from the sd while in the phone. It is much faster if you take it out and plug it into the laptop though. I'm not sure if that limitation applied to the N1 alone or is common with this one. I was thinking of getting a 32 gig because then I could carry all my music and wouldnt have to hassle with it as the internal storage is enough for all my other uses. Knowing what I know now I will likely go with a name brand class 4 card. Too many horror stories with fake cards and my own experience is that the extra speed from class 10s doesnt do much of anything in my usage.
If you do a search you will find several recent threads on SD cards....

You don't need class 10! because this is not a super professional camera. Class 4 is enough (in some case even class 2 is enough 'cause some people say that class 2 speed of some manufacturers is faster then class 4 of other ones).
I have ordered SanDisk class 4 32gb and still wating for delivery...
Choose only good manufacturers, such as: SanDisk/Trancerd/Kingston/A-Data (and before doing an order, check on their official website (and google a lil' bit) if the particular class exist - for example if you will see class 2, 6 or 8 of Kingston on ebay, know that it's a fake since kingston has only 4 and 10 classes according to their website)

I don't know if this is only in the Netherlands but here its possible to get a 8GB micro sd for FREE from Samsung when you registrate your purchase on the samsung site. (only condition is that you buy your device before the end of may)

On my camera I've had issues when recording hd quality movies in anything less than a class 6.
So I'm going for class 6 or above on phone

Which card did you get? Im looking for the cheapest sandsik 32 gb right now, sandisk's are underrated. a class 2 can be faster than a other brand class 4 or 6.

if you google "SD class speeds " the second link down (this is applicable to micro sd as well gents)
it will show you what class you will need for what application eg recording 1080p on your phone will require a class 4 minimum however class 6 is "moar" recommended
however as stated above class 10 isnt needed and if you read a few reviews some class 6 in the case of sandisk e.g. the sandisk extreme class 6 III is faster than some cheapo class 10.

micro SDHC class
so, can somebody please confirm that class 4 micro SDHC card (good brand) is enough for taking videos on GS2? I am looking at 32GB and it seems there is a shortage of class 10 cards in my country, should I buy class 4?

I believe the semi official numbers for 1080P recording on the SGSII is 17Mbps? That means a bit more than 2MB per second. 'Class' refers to how many MB's the card can write each second, so class 4 should be fine for 1080P, as well as many class 2 cards. But of course faster is always better

I bought a class 2 32 gb from amazon.it...
Can you suggest me a program / tool to test its speed?
Anyway, I used it to record a full hd video for 15 mins. I watched it entirely and I didn't notice any skipped frame or stucks etc.. It runs fine

Just plug in to a pc and copy a large file. That will show you the speed.

Have a look for h2testw Version 1.4. It's a free utility that will test capacity and speed. As you may know, the problem with lots of card on sale is that they have been hacked to make it appear that they have a greater capacity than they actually have. It can be sometimes hard to spot but h2testw (and, no doubt, others like it) will do proper checks.

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.

There is a 32GB class 10 sold by Amazon for $42.31 ($52.31 - $10 MIR with free shipping) right now.

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.

TigerDirect is a direct competitor or NewEgg and is 100% legit but I cannot find the card you are refering too. Can you PM me the link and I can post it up for everybody?

The estimated delivery date for the SD on tiger Direct is late Aug. Hopefully that's just a worst case scenario.

I buy from Tiger all the time, personally and for my last place of work. 100% trustworthy company. Been around forever (in computer time).

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.

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:

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.
