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.
Hello all,
Ive got a spare 16GB Micro SDHC card which i have swapped for the stock 2GB version that came with the Desire, but it is only a Class 2.
Having read that its best to use Class 6, should i shell out £50 for a new one, or will i not notice a difference in class ?
Dunno - I'm using a class 2 16gb card myself and I don't notice much slowdown if at all. I'm surprised these things haven't come down in price after two years... key thing is do you notice any slowdown with apps that access the SD card? like I say, I haven't thus far...

i read somwhere that class 4 is enough coz the phones do not support hihger speeds. class 6 will help you if you will take card to the card reader straight to the computer... it think

Thats what i ......... think. Im sure it only matters if its connected to the PC, and in that case i dont care.
I read it on another forum that i wont link too
Class 6 are almost double the price of Class 2.
You don't NEED to get one, I did use a Class 2 card for a few days and didn't have any problems.
Personally I am using a Class 6 now, as I regularly transfer a lot of big media files onto the card, so the extra speed is worth it for me.
If you don't fancy forking out though, you don't have to.
I totally agree, My desire came with a 4gb sandisk class memory card which I initially assumed was class 4 until I took the card out yesterday...connecting the desire to my pc and switching to usb drive mode, i am able to transfer my movies etc to the memory at +/- 8Meg per sec which is more than adequate enough for me...I was about to get a 16gb one but was thinking of getting the class 6 one until i discovered the one I currently have is class 2, so I just made up my mind and went for a class 2 16gb, saved me money....
They only refer to the write speed of the card, i came from a 8gb class 6 and now have a 16gb class 2 and notice no difference, only difference is the write speed from pc to card.
Even though i got a class 2 i still see 4-6mb/s so happy enough with that.
I have a class 10 16Gb card in phone. Read and write speeds seem to be limited to around 8Mb per second (copying uncompressed music). Using an adapter, the computer is able to copy at 14Mb+ using the same card.
They just seem a big outlay for nothing to me, lets face it the only big write time is when you transfer everything across from your previous card once the stuff is on there the write times really won't be much of a problem.
The main reason you will find people suggesting class 6 and above SD cards is due to "Apps to SD". For the Newbies "Apps to SD" or A2SD is a modification that has been done on most android phones (though not the desire at time of writing) which allows the Apps you download to be stored on the SD card rather than the phones limited internal memory. I am not sure if it makes a huge difference to the faster processor phones, but in the G1 days it was noticeable. For just moving music and pictures about it isn't really important to have a faster card and we may have to wait a while for A2SD anyway. I will pop over to the N1 forum and see if they can shed some light on this.
Anyone using a microSD 16GB Class 4, if so are they any good? I'm looking at buying one for the Desire. Also where's the best place to get a deal on one of these card?
Hello, I might need to upgrade the SD card on my G2.
I listen to a lot of songs and 8 GB just wont cut it for me. I have a rooted G2 running desire Z "virtuous" ROM.
I have a few questions:
1. Is this card compliant with G2: Transcend 16 GB microSDHC Class 6 ?
2. Any other better recommendations?
3. I have several important backups etc in my current SD card. What is the procedure to transfer all the data from the old SD card into the new one? (Do I just dump all the data from the old card as-is into the new card)
Most all SD/SDHC cards should be compatible up to 32GB. I have a 16gig class 6 card I used in my old phone and it works fine.
You can copy/paste/dump the files between cards, since SD storage doesn't exactly have a lot of hidden or system files. Or you can copy using a disk/partition tool like gparted in linux, disk utility in OSX, or various utilities for windows.
I had an issue with the bigger SD card in my first G2. It worked fine for a couple weeks then decided it wasn't there anymore.
When I got my replaced (got a new g2) I made sure the SD card was formatted and put it in on day 1.
My recommendation would be to Format the card, then put into the phone. Then drag the files you want on to it.
Another trick is if you want the phone to recognize certain files put them in a folder marked for their use. ie Music, Notifications, Ringtones and Alarms.
Thanks..
I will give this a shot..
I know I am digging up an old thread, but I was wondering what the outcome was for your upgrade. I am planning on putting a 32gb card in my G2, looking at the Kingston 32gb one on Amazon (Kingston 32 GB Class 4 SDHC Flash Memory Card SD4/32GB - can't post a link due to my noob status on forums). I just want to know if that card would work. It seems like it should.
When you format it, does that happen on the phone or do you format it on the PC?
Tried el-cheapo 32gb off ebay - no luck for me
I have tried 2 cheap 32gb off ebay (class 2) and both had issues. I decided to not waste any more time and waiting for a 16gb class 6 (which cost about the same as the class 2 32gb) to see how that goes.
Hmmm....I wonder if the Class 4 would fare any better Anyone out there tried a class 4?
My current SD card is a Class 4 and I've had no issues.
I used a 16 GB Kingston Class 4 that I got from Dell before, but it freaking stopped working out of nowhere, so I'm back to a Sandisk 8GB Class 4, which is working well.
i have a sandisk 16gb class 6. works like a charm.. never had any issues with it.
i am using a 32gb class 4 in my desire z and its working grate.
for the guy that got cheap 32gb sdcards are you sure you wasnt scammed and got a 2-8 GB card that said it was 32gb as these can over write files (corrupt them) with out your knowledge or just refuse to work ones past 2/4/8 GB
The cards actually said 32gb on them. One overheated the instant I used it and melted the sd card holder it came with. Sent it back waiting to get the refund, the other one worked for like a week then died. At first I started to think it was me until I found this thread.

hello guys.
I have a memory card(Adata microSDhc 8gb class6) and I want to replace the old one(samsung microSDhc 8gb class2), because I think the new one is faster, am I right?.. and I want to know what steps need to follow to replace him or simply hand him the old with the new one??
The class 6 card should be faster, although bear in mind that the speed rating is a minimum so a quality class 2 card could be faster than a shoddy class 6 card. As for replacing it mount your SD card to your pc copy everything to the pc, install your new sd and transfer everything back, job done.
I understand, thanks. but I'd like to say your opinion if it's worth to make this change ?
for me no, samsung cards may not be the top of the line but they are good enough.
and the fact that it's only 8GB, getting a faster class cards will be worth it if you're getting those higher capacity cards 16gb / 32 gb.
ok thanks. remain with the old one ,and I will change when I'll buy a card of 16gb or 32gb. but are so expensive in our country :-<

Personally if you've got the card there I'd give it a go download SD-tools and benchmark both cards and keep the faster one, I find that faster cards do improve life sometimes with faster gallery load times and less likelihood of stuttering when recording HD video.
Actually i too had an 8 gb class 2 and i upgraded to 8 gb class 6. The problem with class 2 is that videos recorded at 720p start lagging when you play them with a class 2 card. I had this problem with the new sd card i got with my dhd. it was a class 2 and videos at 720p would lag like crazy. Got a new class 6 and the problem just disappeared.
Now here's a question for all of you:
What is the MicroSD Card that is included with your phone? I know it's a 16GB, but does yours have a company branded on it, and also what class is your SD card?
The reason I ask this is because I want to know if they switched the SD Card on my phone with a crappy one and took the good one just before I picked it up. The SD card that came with my phone is just a plain generic Class 2 card. CLASS 2!! It doesn't even have where it is made at. I'm thinking, are you serious?!?! The transfer rate is so horrible, averaging only at 1.5MBps. Takes me over 30 minutes to transfer about one 1GB of files.
My friend who got the rezound at least got a Class 4 card, even though it's generic and made in Taiwan. But his transfer rate is averaging at 15MBps.
So I just wanna double check with all of you and make sure we all have the same type of SD card.
p.s. Also, this could be the reason why the phone sometimes perform sluggishly. I have a feeling when it pulls anything from the SD Card, may it be a large app, music or videos etc, it will have to wait to read from it.
OH! could this be the MAIN reason behind the slow response when taking pictures? I read that this phone has a horrible camera speed, but it might be due to the SD Card being slow and can only write at very low speed to the card.
I also noticed the slow performance of the included micro sd card, and I can't even access it from my card reader, but only through the phone's "mass storage" mode. Anyway just ordered a Sandisk class 4 32GB card from amazon...
The default card that came with mine is a Class 4 8GB made by Kingston. It doesn't say Kingston on it, but I have an actual Kingston SD card to compare it to.

If that's the default save spot, then yes, that could possibly be the issue. How big are the pictures?

8GB class 4?? wow that is small in size, although it is a class 4 card. Livid, is it because you are on Bell? Could this be carrier related? Also, how is your camera? Is it having that speed issue in between pictures?

bmxant, I took some pics and at full res, they average at around 1.3-1.5 MB, which is just right there with the speed, giving it a second or 2 delay in storing/saving them onto the sd card.
Sandisk Class4 16gb in mine. Mine was ordered and sent directly from AT&T site...I'm leaning toward them swapping out the card on yours.
If you're only writing at 1.5Mb's, that would definitely cause an extra second of lag. Would be nice if we could see a comparison between the Class 2 SD card vs Class 4.
How much cheaper could they get? It's bad enough the phone has 4GB of internal storage. They should of included either a 32GB Class 2, or 16GB Class 4.
Edit: Just read Namuna's post. Why would they swap out the card?

Alright thanks, I just need some more confirmations and I can visit the store again and confront them with it. I will make them open a fresh box in front of me and check it, unless of course they've swapped all in that store lol!
@aquariuz23: It probably is carrier related. You guys got double on the SD storage and RAM storage versus what we got. I feel a little screwed in that regard, but meh.
For photo taking, it only took one second to snap the picture and store it on the card. The gallery took 5 seconds to read 84 pictures that were stored on the SD card.

That sounds pretty good, what does Antutu say your write speed is?
Topram Class6 16GB here. SD Tools report 18.5MB/sec read and 5.5MB/sec write, which is pretty accurate for C6. (btw, card manufactured in 2009)
This phone I bought used, can't confirm the card is the original.
6.3 MB/s write and 13 MB/s read. It's about average for a Class 4 SD card.
what do u guys use to test the read/writes of the sd card? I wanna do a test on mine as well.

I always used Antutu
Tested with SD Tools
http://www.amazon.com/KOMPUTERBAY-C...&s=electronics&ie=UTF8&qid=1325197909&sr=1-11
Think this is worth it?
I am getting an average of 2.9MB/s Write and 11.1MB/s Read. Seems like a typical class 2 card. Took it a while to run the test too since it's so slow lol.
I got 5.4MB/s write, 15.5MB/s read (Antutu) on the 16GB Class 2 card from my Captivate that I wiped and stuck in the Nitro and gave the one that came with it to my Captivate (running hacksung's ICS). Is the included card that bad?
According to AnTuTu:
3.4 MB/s write
>50 MB/s read
According to SD Tools:
5.7 MB/s write
20 MB read
Nothing like some consistency between utils.
