has anyone been able to find the Sandisk Micro SDHC card specs/speeds?

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.

Can the Herald transfer at Class 6 SDHC speeds?

Hey everyone.
Just a quick question. I know the Herald supports class 6 Micro SDHC cards, but what I'm wondering is does it transfer at Class 6 speeds, or only Class 4? My choices of Class 4 cards is vast, but I want to know if I should bother taking the extra effort to invest in a Class 6. No point hunting around for a Class 6 if the Herald doesn't transfer at that speed.
Anyone got any idea?

What Micro SD Card: Class & Brand

Looking forward to finally turning my phone into my day-to-day mp3 player, as well as running debian and apps2sd, I've been reading all the latest threads about sd cards and finally decided the most optimal config is a 16gb class 4.
Reasons:
· Class 6 is unnecessary as the nexus wont really take advantage of it.
· Class 2 may be kind of slow for apps2sd and debian, which I'm looking forward to investigate on.
· 16gb because although 32gb is comming, it will probably be too expensive for me.
Benchmarks:
I've looked through eBay and found a few interesting "offers", both at about $40:
SanDisk 16GB Class 2
TOPRAM 16GB Class 4
I really want a Class 4 for all I've been reading lately, but I can't afford a 16GB Class 4 SanDisk.
Does anyone know anything about "TOPRAM"? I had never heard about it before and I'm wondering if it could be a low-quality card.
Any help will be greatly appreciated.

No one knows ANYTHING about TOPRAM?

I've seen ppl complaining on the internet about the device not recognizing the sd card, but i guess that happens sometimes..i think..o.o

I have always used A-Data cards, been happy with them.
here are some speed test people have done http://wiki.cyanogenmod.com/index.php/SDCardSpeedTests

I use and trust PNY class 4 sd cards never failed a year in my rooted g1 and still going with apps2sd and so far with my nexus

With all the talk about SD card speeds I've been seeing lately, I was starting to regret buying the SanDisk 16gb class 2 and not getting a Class 6. But after looking at this chart, I can't imagine why I would need more speeds than that?

I have a 16GB Team Class 6 from ebay

I'm using a Polaroid 16gb class 2. Seems to be working fine for me, even running apps2sd.

I have an 8gb class 6 from RiData. seems fine to me, used on my MT3G, HD2 and now my N1.
i do agree with you though that a 16gb class 4 might just be the best cost/performance

Since we are talking about storage memory, I have a slightly unrelated question. Which is the better, microSD or internal storage that comes with some of the phones out there? In terms of speed, reliability, and cost, which one is better?

With regard to Class 6 - don't write it off if you plan to remove the card from the phone to do movie or music transfers. There are a lot of microSD adapters for computers that can exceed the performance of a Class 6 card and so if you are commonly hooking it up to a computer to transfer media then you'll be glad you went with a Class 6.
Now, if the capacity gets high enough to store all of my music, then I won't care about that issue, but personally I can only store a subset of my music on my microSD card so I do worry about the speed when attaching it to a computer...

i have that TOPRAM sd card on my nexus one i got from amazon Usa and it work very well

Class2 is definitely slower
I've used classes 2, 4 and 6 in an HTC Magic. I used apps2sd with Cyanogen Mod.
My own experience was that Class2 was definitely slower when using apps2sd. But Class4 and Class6 were better...and didn't appear to be much different. I had Class6 sdcards anyway as that is what was recommended for most of a year. They performed well.
The last ones I bought were Class 6 8GB Transcend MicroSDs for NZ$40 each (US$28-ish). That included 12.5% GST.

SDHC Class 4/6/10???

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.

[Q] Which SD card should I choose?

Hi,
I'm considering to upgrade my SD card to a newer one and need some help please.
These are my candidates, price is almost the same:
KINGSTON microSDHC Card, Class 4, 32GB (SDC4/32GB)
KINGSTON microSDHC Card, Class 10, 16GB (SDC10/16GB-2ADP)
I think Class 10 speed will never be used by my phone. Class 4 is enough. Is this correct?
Also interesting if anyone tried a 32 GB microSDHC in Hero? Does it work?
Thanks
I gave Hero GSM with CM6.1
