I just wanted to know the speeds of the SDHC cards, i wasnt sure how they compared to SD ultra II cards. I just havnt been able to find the specs anywhere so far.
When I bought my 4 GB sandisk SDHC I asked the salesman about speeds. He searched many places, even at the manufacturers homepage, without finding any specs. He sent a mail to sandisk, but I havent heard from him yet.
I'll tell you the results when I hear from him...
On the card itself, there should be a number in a circle. This number is the rated write speed of the card, in MB/second. This PDF from SanDisk should provide more detail.
All i know is that they are class 4 cards, and that they are much faster than regular sd, micro sd cards, but not as fast as USB 2.0 or firewire.
After reading the pdf, it appears that there is more than one class. My 6gb card says that it is a class 4, so it would transfer at 4mb/s.

hmm, well as long as the kaiser can take full advantage of that 4mb/s then that's pretty good.

i would logically think that it should be...i mean, if it can accept SDHC, then it will prob. be able to utilize it.
The 6GB and soon to be out 8GB cards are all currently "Class 4" which is 4mb/s; ScanDisc is the current leader in bringing Micro SD card technology to market and to this point there have been no indications there is a "Class 8" or higher in the immediate future.
4GB cards typically will be either "Class 4" 4mb/s or "Class 2" 2mb/s. If you see a really cheap 4GB card there is a good chance it is a Class 2, so be careful.

I don't know what BB has, but the 6gb I bought online a few weeks back is class 4. According to Sandisk's site, all their 6 gb cards are class 4, and all their 4gb's are class 2.

Higher speed media?
Amazon is selling a 2GB SD card for $40.85 where they claim:
Product Description
The Sandisk Mobile Premier microSD Memory Card offers all the benefits of a standard Sandisk microSD card plus higher performance and TrustedFlash technology for premium content storage on next generation phones. Write at 10MB per second and read 9MB per second for higher speeds to increase the functionality of your phone's storage capabilities. Listen to more songs, view & print more pictures and store more videos.
the link is:
http://www.amazon.com/Microsd-Premi...1?ie=UTF8&s=electronics&qid=1192552982&sr=1-6
many ppl are mistakening about what the classes refer to, there are 3 class 2, 4 and 6, this means the minimum write speed the micro sd can achieve, in other words, the class 4 and class 6 may not even be faster than a class 2.
I have te following and did a simple test using the hd tach.
toshiba 4GB class 4
sandisk 4GB class 2
sandisk 6GB class 4
all cards offer a write speed at just over 4MB/S
As for the read speed, both sandisk is about 11MB/s, whiles the toshiba is at 20MB/s
on the market apart from these, there are others, like kingston and eagletec (toshiba OEM), and may be some others.

I go the 6GB sacndisk from Buy.com for 70$
It seams slow, when programs access the card it seams to stop for a second.
Like using it IE or attached files of email.
and finaly every this was gone, and format it again..
Don't know what's going on...

Heya,
I'm sure this topic has been discussed but I can't seem to find a clear answer. It's obvious that the HTC Hero is somewhat temperamental with certain makes and classes of Micro SD, or the assumed Class 6 isn't always as fast as people hope.
In my case the 2gb stock card is just going to be too small so I'm keen to purchase the biggest card the phone will support (which is 16gb?) or 8gb. Is there a card in particular which stands out as being the best (in terms of speed) for the HTC Hero at these sizes?
Thanks
i think the biggest possible micro sdhc card is 32gb, but i´m not sure and it was not worth to me so i bought a 16gb and it works perfect
Are there 32GB micro sd cards available?

find Sandisk 32GB micro SDHC is already available for pre-order, but no specific date of release.
I just bought a Sandisk 16GB micro sd (class 2), appears faster then the 2gb stock card.
Try to search some technical reviews of different SD card with statistics. Much better than relying on "CLASS".
Class is important
Hi, I would say that in a price/performance view you should go for a 8GB class 6 card right now. The class says how fast the card can transfer data. Class 2 does 2MB/s. Class 6 does 6MB/s.
32GB is the limit of the SDHC format. I have 8GB now and I guess I upgrade to 32GB later when prices get better.
for sandisk, class 2 = class 4, class 4 = class 6.
as i know, some class 2 is actually much faster than the standard minimum speed.
I have an 8 gig in my phone but its having trouble rescanning the card i have like 4 gigs of music on it and I think thats too much for the phone to scan, that would be my only thing to maybe consider.
Ps if anyone has a solution for my problem that would be great haha
Unless you despareately need to store A LOT of data on your phone get the fastest card rather than the largest.
8GB SanDisk Class 6 card is about £17.
16GB SanDisk Class 6 is nearly £50.
Prices will drop rapidly so for now I'd go for 8GB at 6MBPS over 16GB or 32GB at a lower speed.
Hi - Following on from this, has anyone used a 32GB card and proven it works. I'd hate to get one and find out that it's incompatible with the G2 Hero.
32GB microSD cards are out?!

The 16GB Class 6 you list doesn't seem like that much of a stretch to me, it is a wee bit over twice the price, but not ridciulously so (i.e 3x the price). It is the best MicroSDHC card that money can buy, and the transcend one I've got is nice and fast (pretty sure it was less than £50 too, now that I think about it).

Nup, no 32GB MicroSDHC cards as yet fellas, all the sites I've seen, list the Sandisk one for Pre-Order, but its been like that for 6 months, so maybe they're planning for a 2010 release?
Err is that spam?
any offical word or tests showing that a class 6 will work to its full speed... rumor I have heard is the hardware in the hero (us version) will utilize up to class 2 speeds.
(Not to say a class 6 wont work. just that it will only be reading and writing at class 2 speeds) Can anybody confirm?
I can maintain 6-7MB/s write speak to my 16GB Class 6 which is Class 6 speeds. Not as fast as I'd like (SD speeds), but worlds better than the Nokia N95 8GB I had before which was limited to 800-1000KB/s (only USB 2.0 full speed as opposed to hi speed).
qwiksand, is that from your hero or from a card reader?
I am trying to find the source now but cant rummage up my history; i swear i read an email from HTC saying the card reader in the Hero was a class 2 reader, thus nullifying any performance increase from a class 4 or 6 card.
hmm, you're making me doubt myself now!
I'll do a speed test today both in the phone, and out.

Likewise,I'm sure I read an official source saying that it would only make use of 16GB irrespective of the size of the card. Sounds more dubious but I'm not going to risk it with my own money!!
Any updates? Want to get one on black friday
As what i know G3 Hero only support up to 16gb sd/sdhc card.
As the class on those card are for writing speed & reading speed is all the same.
edit: i have found some news frm somewhere...
Good Morning Frank,
Thank you for taking the time to contact HTC America Technical Support via E-Mail with your inquiry about what class of SD card to use in your Sprint HTC Hero. My name is A.J. and I will be happy to assist you today.
If you are looking to purchase an SD card that the device will read at its full native speed you will need to purchase a class 2. The device will read a class 4 but not at its native speeds.
Frank, if you have any future questions about your device please feel free to visit HTC - Touch Phone, PDA Phone, Smartphone, Mobile Computer and send us another e-mail. You may also enjoy HTC Smartphone Wiki - HTC, which has a plethora of information on HTC devices, including the Sprint HTC Hero! I would also like to invite you to participate in a customer satisfaction survey located at HTC Online Survey I hope you have a great day!
HTC America Technical Support

According to HTC's website the Hero can use SD 2.0, SD 2.0 is another way of saying SDHC, just like devices that are compatible with standard SD, the device is expandable to the limit of the format. Therefore, the Hero CAN do 32GB because it is SDHC compatible. Only problem is the 32GB Cards have yet to be mass produced.
i've read here and there about microSD card classes. i want to flash the latest cyanogen mod to be able to use apps2sd - so what class/type memory card should i buy?
The general consensus is that class 6 cards provide the best speeds with apps2sd roms. But then some ppl say they don't really notice a difference. Personally I use class 6 and can say that they work great.

You should buy an 8GB class 6 from A-data ! Their memory cards are superb compared to others. I have tried Kingston, Transcend and some other stuff but nothing can compare with A-data
go for an 8gb or 4gb class 6 sandisk.
They're hard to find but are the fastest around.
And you've actually heard of the name!
Always used the fast 4gb class 6 Sandisk one.
Use the cheapest class 6 of the size you want on Newegg.
Just wait for SanDisk's 32gb MicroSD, more space for more apps, music, and movies
I found that some SanDisk cards don't have the class number written on the cards.
What does it matter that the class number isnt on the card? Just look at the box when you buy it
using a class 4 PNY 8 gig card works fine with apps2sd.
im also looking to buy a class 6 16gb card. Plz tell me which one should i buy from www.newegg.ca
was thinking A-data or Ridata

Most plain blue Sandisk memory cards are class 2. It's not until you get into there ultra series will you get class 6 speeds. They don't mention it so it's easier to disguise products and not make it comparable to other brands.

Hello!
I want to buy a 8gb class 10 mSD for my [email protected], but i see some other thread from other forum, they said that the maximum r/w speed on HD2 is only about class 4,
Which means if u insert a class 10 (or class 6) sdhc card, actually, the speed was only class 4's speed...
Is it true???
Thanks
That will be good to know, because I was thinking of buying a new card as well.
The G1 and MT3G can support up to class 6...I'm sure the HD2 can support class 6, not sure about 10 though
You would be fine with C6 cards just make sure you don't buy any BS get it from reputable dealer. Using SD2.0 on HD2 you won't see passed class4-6 as the device is limited but not the card, you can however get class 10 card and use card reader to transfer content but while the mSD is in HD2 you will be throttled near C4-6 range. IMO go for C6 if you plan to use any type of heavy use that would require large access on mSD if not then go with C4 you will be perfectly fine.
People worry too much about card class. I'm using a fairly standard class 4 card and I've never been frustrated even when copying android with a 1gb data image to it
I cannot see any difference speed between class 4 and class 6 8gb SD card. anyway, be sure to buy a known brand name.
Looking to get myself a 32gb card.
Just wondering if the play uses SD or SDHC memory cards, or ok with either?
it uses microsd and microsdhc
regular sd card wont do
Yeah, obviously I know it's micro.
Just wasn't sure about the sdhc.
Cheers
It's ok with both sd and sdhc but I think it's not compatible with sdxc (if you'd ever like to get to 2TB maybe it can come in an update, My htc wizard got sdhc support with an unofficial driver update).
A 32 gig card will work just fine with the Play.

I heard there's problems with class 10 32 gig micros on android phones. Is this true?
i'm curious about this, some applications wont work with a class 2 speed sd.
sd or sdhc would do. you should be more worried about the speed. as for now you should think of either getting a class 6 16gb or class 4 32gb (if you could find one).

I have class 10 32gb, works fine on xperia play.
The only problem android has, is you cant format 32gb cards on your phone. But most, if not all cards come pre-formatted anyway. Otherwise you have to connect the card with an adapter to your pc to format it.
*edit
You can format 32gb cards on your phone, but it wont format properly and you will have issues. I did with my old phone, it couldnt scan the card properly and it would reboot while trying to scan.

now that's something
read most of the reviews: crashes and corrupts the files, some even only last within 24 hours i'll stick with the class 4 32gb for now
even with the sandisk 32gb class 2 cards, i already replaced 2 of them when they crapped out on me

haven't read anything about this. and the reviews for a kingston 32gb class 4 on the net has been great so far. but if this will be the case i might just go for a 16gb class 6
Ok, so I got a 32gb card, moved all of my stuff off my 16gb (about 14 gig) to my pc. Took about 20 minutes.
Put my 32 gig in, formatted it & transferred everything over.
Took about 3 hours & when I put it in my play it's saying there's 28 gig left & hardly anything I set to transfer has actually gone to the card ! ?
Do a full format and not a quick format.
Ive seen a class 10 32gb micro sd card for 50 quid, but im worried that its too cheap and might not last long.

Memory cards are very reliable IF you bought the original ones and not those unbranded fake cards.
I've never had issues with ALL my memory cards, from the SmartMedia, SD, MS stick and Compact Flash cards used in my Palm and Sony Clie PDAs, my DSLR and micro 4/3 digital cameras, PSPs and DSL and all the way to the microSD cards used in my smartphones and tablets. I purchased them all from local reputable shops and never bought any from online stores. Can't remember the exact figures but I probably had a total of 30 to 40 cards here in my house.
The problem I see is those cards that are found on online shops that are unbranded (anything not Sandisk, Kingston, Lexar, Panasonic etc are all semi-fakes). Just imagine that Sandisk the world's largest NAND Flash memory maker has yet to come out with a 32GB Class 10 microSD as of now and you can already find some smaller unknown companies selling them at very cheap prices since many months back?
Sometimes if a deal is too good to be true, IT IS too good to be true! Of course if you still proceed to get them due to their ridiculously cheap prices, the risk is all yours. For me, I just buy the originals at original prices and not regret it later, my data is much more important to me than saving tens of bucks.
For some reason, there are quite a lot of fake Kingston cards on the market so beware.
Various issues with the fake/unbranded cards are:
1. Reliability
2. On a 32GB card, you may actually get only 4 or 8GB storage, some tricks were added in these fake cards such that once you copied beyond the 4 or 8GB capacity, it automatically loops back internally to overwrite the oldest copied data.
3. Some 32GB Class 10 cards only had Class 2 speeds.
Another advice is that for smartphone usage, you may be better off getting Class 2 or 4 cards rather than higher class cards. This is because although the class 6 or 10 cards can have sequential readings and writings at their stated class speeds, in terms of random access of data on the card they may actually be slower than Class 2 and 4 cards. In other words, you'll get more lags using higher Class cards.
Here's a test I did with a Patriot LX Series Class 10 32GB Micro SDHC

You sir are correct! My Patriot 32gb micro class 10 lags alot When playing the FPSE the game lags too much but with the micro sd card that came with the Xperia play runs perfect I'm gonna return the card and just get a Sandisk 32gb class 2 from newegg.

After doing a test of manually copying content to the card I believe I have fallen foul to buying a cheapo card covered by your point 2.
I've bought quite a few cheapo cards back from my old K750i & PSP days but this is the 1st one I've been stung with.
Live & learn etc !
