Is it worth paying extra for a faster micro-SD card?

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.

32 gb sandisk

hi, i hope this is right place to put this and also to let you know i did do a search of the forum and couldn't find an answer...
i just bought a 32 gb sandisk micro sd card and inserted it into my galaxy s, i have tried to add thing to this via my pc and also via astro on my phone, each time it seems to get a little of the way and then the external sd card unmounts its self (at least i think thats whats happning ) and then i get an error on my pc saying the read/right disc was unreadeable, then my pc says that the external memory needs formatting before i can continue use, if i then go back into my phone i notice te external memory is no longer mounted, this is driving me mad, if anyone can help please do before i throw my phone out the window lol....i am using a rooted galaxy s with 8gb onboard memory

It sounds like you have a bad card. I would return it for a new one.

Let me guess, eGay. . . . .
I have 2 fakes sitting right here. . . . This is a huge scam.
Buy memory from reliable sources only.
my 16Gb card is a 1Gb in reality.

Hmmm...did you make sure that the USB mode is set to debug and then the dial up mode is off. This same thing happened to me last night. Make sure that's done. Restart the phone and THEN plug the cable in. I'm guessing it keeps flipping out and there's a red pyramid in the upper left hand corner?

Bad Memory
I believe you got a "fake" memory. I have experience of this before. A lot of programmer will be able to re-program the card from 2G to 32G or whatever the capacity they want. just google it, there is a free program will be able test it and tell you the real capacity your card has it. if the price is incrediblely low, there will be a problem. if you got it from ebay, just dispute it and get your money back.

Look for the program h2testw, it will tell you actual capacity of your card, likely 64-512mb only.

Yes, scams. You should only buy to respective shops. Sadly some of my friends bought things like 10pcs. Too bad they got scammed. I learned my lesson and it is just somehow like 3-5$ difference.

I'd say stick to Newegg and Amazon for memory purchases.

Which is the best company for 32 gig class 10's

I've bought 8GB and 16GB cards from those Chinese deal sites. They worked out alright. They weren't too experience. But I agree, if you want a 32 GB card, go buy a reliable brand from a credit-worthy source.

where can u buy cheap memory cards

I'd say Sandisk is the best quality memory card you can buy. Class 2 and 4 Sandisk work great for WP7 or for running Android off of on a HD2. Class 2 and 4 cards generally have a better random access speed than class 6 or 10 cards. You only want higher class cards for digital cameras where you are writing a lot of file sequentially. For running operating systems where itneedsto read small amounts of data from many parts of the card quickly, a quality class 2 or 4 card works best.

You should test the card with CrystalDiskMark and HD Tach to get the random read and write speeds and random access time. I'm curious as to how the class 10 Lexar rates in those speeds.

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.

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.

I agree with Pheno.menon but the price might be worth the shot. Just make sure you use Paypal. I have tried a few of these even named brand and had the file with Paypal to get my $ back. You also want to test the speed if you get get one. I had one marked as a class 6 but wasn't even a class 2. Made the phone freeze up.

I remember reading about a delay when unlocking the screen whenever an SD card was installed. Can't seem to find anything about it now though. Anybody know what I'm talking about?

I get the slight delay but the thing with mine is i get the delay whether my sd card is in or not.

I remember back in the day on the G1 when you had to run apps to sd and partition your card. I bought a supposed class 6 8gb card on eBay for cheap. It was definitely slower than my Sandisk class 2. I'm using a 32gb class 4 SanDisk I conned my buddy out of his Thunderbolt. Must say so far I like it. Try craigslist. I know I picked up a 16gb for cheap a while ago...

I bought this one from ebay.

higher class number means higher write speeds, but that doesn't always mean better read speeds.
IMO higher class cards are better when your doing photography and video stuff
I read my card more often than write to it so a lower class card with better read speeds is better for me.

any big difference between a class 4 32gb, vs a class 6 or 10?
i mostly plan on having old pics/vids + music on my 32gb micro sd, and having all my new pictures/videos recorded to my internal memory.

The class dictates read/write speed, with the number representing megabits per second.
