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 bought a class 6 off Ebay and it should be here on Monday so I can compare then

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?
Have just acquired a Touch Pro 2 on eBay, and am now thinking about getting an SD card for it. I assume the TP2 supports SDHC...?
I can get a 16GB class 2 card for about £30, or a 16GB class 6 card for £50. Am I likely to notice much actual difference in speed between the two when used with a TP2?
Depends.
In day to day usage of the TP2, no I don't really think so. You're not going to be able to take pictures any faster (the camera isn't capable of fast shooting), movies will run fine from a slow card. Maybe searching through your email would be a bit faster, if you have a lot, but I can't imagine it will be significant.
Where you would see a difference is if you take your SDHC card out of the TP2 and put it into a PC for dumping lots of data on it at once - for example, copying over lots of MP3s or movies. If you're transferring multiple GBs at a time direct from a PC, you will notice a worthwile % increase with the faster cards.
So if you do that regularly it might be worth it. If you tend to change the data on the card only infrequently, then I doubt it is.
Personally I will be getting a slow card. I only have a fast card SD card for my Digital SLR camera, where the faster card enables more shots to be taken per second.
whatever you do do not get a Transcend class6 16Gb card. They are not compatible. I know there's a thread listing card compatibility in the rhodium forum, but I couldn't find it now.

Wow, thanks for the warning, that was exactly what I was thinking of getting.
firstly i beleive the class relates to write and not read speed.
second do not buy a card off ebay whatever you do.
i have come accross an a-data 16gb class 6 in my searches. in the end i got 8gb class 4 from play for a tenner delivered. may get a 16gb if i ever hit the limit. by then the price will have dropped to reasonable level.
i had a 2gb in my xperia and never filled it. i have a ipod touch for music and a netbook.

all the cards i have ever bought off ebay have been fakes.
some have worked but been slow. others have corrupt sectors. some have failed all together. thankfully last time pay pal refunded me.
look at www.sosfakeflash.wordpress.com/
buy the card if you want. that site has programs you can test it with to determine if its legit. i will never buy a memory card from ebay again.
Class only deals with write speeds, not read speeds BUT if the card has a higher write speed, it will normally have a higher read speed as well. (Though it's not a set rule).
Thx for the heads up. I think i'm going to risk it anyways. This seller has been on there since 2000 and has sold a ridiculous amount of flash memory ~20,000. I would hope the system would show some signs of fakery over that span of time.
I will try the tool you linked once it arrives tho.
Thx again
PS here is the ebay item # if you want to look: 380143609813
I decided I didn't really need 16GB of storage anyway, and ordered an 8GB class 6 card - a SanDisk Ultra. Got it from these guys on Amazon UK Marketplace.
They have a pretty high turn-over - nearly 30,000 ratings in the past year. I also used this tool to check whether the card was genuine or counterfeit. It passed with flying colours (no errors at all) so I think it's probably the real deal.
A quick, informal test (copying a 700MB file onto the card) suggested it was writing at about 12.5MB/s when the card was connected directly to the PC's USB port, and about 5.5 MB/s when accessed via the phone (in disk-drive mode). That suggests that the phone might get some benefit from a class 6 card, although it's hard to be sure. Certainly this a is a VERY fast card when removed from the phone and connected straight to the PC. (In fact the testing software rated it even higher - 14.9MB/s write, and 17.5MB/s read).
No reliability problems of the sort associated with the Trascend cards (although I'm not sure that affects 8GB cards anyway).
Trancend 16GB Class 6
I currently have a Trancend 16GB Class 6 and it works just fine.
I only buy cards from Sandisk and usually from amazon. EBay has a lot of fakes on it! I have a 16GB Class 2 from amazon that I picked up for $40. Speed test while in Disk Drive mode through the phone show a Write speed of 3.8MB/s and 6.4MB/s read speed. I have 10GB filled so far and It didn't really take that long to do. I'd say if you were filling the card up with 10GB of new music a day then yeah those speed suck but for a few big loads just to get it started no big deal to me.
I can stream a 800x480 AVC ~1.2Mbit off the card with no hiccups. So I'm not worrie about the speed considering anything more then that the processor becomes the bottleneck not the card.

Do you use your tp2 for music?
try playing a few songs in a row from the music tab with screen turned off...
I just recieved an A-Data 16GB Class 6 from ebay. Seems to be fine, passed memory test with no errors @ 8.9MB/S write and 15.1MB/sec read.
Worth the money just copying video and music files to the drive via pc. Way faster than my previous 8GB Class 2. Don't notice any real difference in the phone tho.

I had a Transcend 16Gb class6 that disconnected if I tried that. I had to reboot to get the card to register in the Phone.
Been out on the road for work all week using music over bluetooth and co-pilot 8 heavily. Working like a charm.....maybe i just got lucky.
I'm putting my $0.02 on the table on MicroSDHC cards. Basically for those of you that want faster data transfer on a larger card like an 8GB or 16GB MicroSDHC, it can make a difference but beware of brands that are not well known and their transfer speeds. The Class ratings on the MicroSDHC cards only apply to their guaranteed throughput rates and are NOT indicative of the actual speed experienced on the cards. I've seen some Class 2 Sandisk cards outperform Class 6 A-Data cards before which is a little scary.
are there any class 6 16 or 32 gb cards?
my class 6 8gb card just died and im looking to get more space to get rid of my ipod but i dont think a class 2 card would be fast enough to handle 12gb worth of music fluidly like a ipod....
i tried looking for some san disk class 6 cards but i can only find class 2 16 and 32gb cards
and some random "ts" cards that say their class 6 which i really doubt they are

They get kinda warm, or even kinda hot, and can burn out. Especially in the Evo, underneath the battery, which already can easily get >100 deg. F, and not being able to vent.. yeah. Also if it's a cheap card it can just be made really crappy and r/w operations can damage the memory
How do you verify the card is real? I bought a 16gb class 2 from eBay. It says scandisk on it and it only cost 26 bucks. I haven't seemed to have problems with it, but worried about the overheating.

Use h2testw to check for capacity. You can't really tell if it is sandisk or not. Check the read/write speed using atto disk benchmark.
Anyways, a class 2 16 gb microsd goes for ~30-33 on Amazon via third party seller/fufilled by Amazon (less likely to be fake)

if you have a sandisk chip that you know is genuine, compare the two chips. Other wise Google image for a sandisk chip and compare. I think that sandisk usually has a serial or part number on the chip. Not sure of the details but I've heard that fakes are usually lacking something. Also compare the size and build quality to the chip that came with the phone. Sometimes fakes are slightly larger or have crappy glue jobs. Google how to detect a fake. There's some good info. Most of it is what I said.
Ok conducted a test and got this.

which is card to get ?
you know... i personally would go with some 8 gig class six models, example, transcend is selling the 16gig class 6 for 64.99 on new egg but also selling the 8 gig class 6 for 19.99.... which means you could get 24 gigs for less with over 5 dollars to spare which you could use to get a nice 5.99 2.0 card reader all free shipping. besides most custom roms and all future android updates use apps to sd which shortens the life of you sd, why put all your eggs in one basket? i had 2x 8 gig cards on my g1 using apps to sd for a year and a half and never opened the second 8 gig card sold it in its package when i sold my g1 had 1 gig ext3 partition 256 mb swap, plus over 2 gig of music and a bunch of t.v shows its hard to fill up an 8gig card on a mobile device.
I wish I knew about the class 10. I just got an AData 16gb class 6 for $59.99 to replace my other one that went bad.
I know speeds are:
Class 4 - Minimum of 4 MB/s performance.
Class 6 - Minimum of 6 MB/s performance.
Class 10 - Minimum of 10 MB/s performance.
Can the Galaxy S even get up to class 10 if I go that route?
Yes, it matters a buttload.
Yes the Vibrant can make full use of the fastest chips out there.
Spend a few dollars more at Newegg and get a good chip from a known maker (Crucial, PNY, Micron, etc). The stuff is pretty cheap anyways....worth a few bucks just for piece of mind.

I'd suggest staying clear of Kingston and *possibly* Patriot.
I've nver seen Kingston stuff work as advertised and Patriot is a hit or miss at best.
Agree with n2ishun
I agree withn2ishun
Crucial and the other he mentioned are way more ereliable and have a better burst capacity (ability to write for shot periods of time faster than normal benchmark).
SD Memory Card basic breakout these are just averages i have in my phone a 16 gig card that claims 20+mb transfer rate never checked it but it is fast

I dont know much about phone memory. i'll be getting my first smart phone this week (vibrant). I followed the link and the only company you had listed that i saw was PNY and they only sold cards at class 4 speeds. So besides kingston and patriot are the other's ok? Centon had a few class 6 cards that i was looking at. Or perhaps i should be asking are there any other companies i should stay away from?
thanks in advance
A lot of brands are okay. Well, that is if you buy it from a legit retailer and not from ebay where there is a chance for you to get a fake one.
Sandisk, PNY, Kingston, Adata, Transcend (I have a class 6 one), Crucial, and etc. They are all about the same. Go to Newegg for reviews.
Ah ok.
thanks alot.

I wouldn't say "impatient" but sometimes we have better things to do than sit there and wait for a file to finish transferring. Especially big files.
Usually files don't really get big enough on phones for 4mbs to be a huge problem.
But I'm not going to argue with you, the faster the better definitely. The good thing is there usually isn't a big difference in price between the different classes if you're shopping in the right places either.
the stock card is a class 4. I have an 8GB class 6 from my G1 days when we were doing 3 partitions on one card (crazy to me now). Does it matter? Yeah... Is it worth spending a lot of money on? Matter of opinion... how much are you using the sd card for read/write? I use the internal memory most.
I can see speed being an issue if you're taking a lot of pictures and video and saving to SD card. I usually use my external just for music, so Class 2 is fine for that (still, wouldn't turn down a Class 6 card if the cost differential were slight).
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.
