[Q] What class is my micro sd card?

---

Hi all,

This should be a quick answer...

How do I know what class my micro sd card is? Its a San Disk 8Gb. Can I assume the little 2 in a circle is the class? Would I be better getting a class 6 card?

Thanks.

Owen.

corect the number in the circle is the class. I running a class 6 samsung and in all honesty no earth shattering diff in 99% of thing phone can do

Hello terzer,

without number on the card only a transfer test can give you an answer.
When you have an adapter to use the card with your pc card reader, you
can stop the time to transfer e.g. 100 MB to the card. Devide the 100 MB
by the time and you have the writing transfer rate (e.g. for 10 s:
100 MB / 10 s = 10 MByte / s ), repeate this with reading the 100 MB
back and you have the reading transfer rate.

Class 2 - 2 MB/s minimum writing
Class 4 - 4 MB/s minimum writing
Class 6 - 6 MB/s minimum writing
Class 10 - 10 MB/s minimum writing

Stop time after finished copy process - pc somtimes uses write cache
and displays multiple of real rate.

There's a sd card speed tester on the market. I forget the exact name. Try that to find your class.

sent from my dhd

I test transfer speeds with "J Disk Benchmark". No idea if it's the best or anything, but it gets the job done and it's free

It's "SD Card Speed Test". I guess someone with a huge imagination named it

Just ordered a new 16Gb Class 10 Transcend card from 7dayshop.com £16.45 delivered

Just have to wait an age for RM to deliver it, over Christmas.
