SD

[Mancini]

OK ,I got my Gopro Hero HD 1080p and nice Sandisk Extreme 10class SDHC 30MB/s ==== yeah right I wish..it's just another bloody crap copy ,how I know ?
Well everything should be fine ,it's even same SDHC card as it's on Gopro website but not 16GB or 32GB only 8GB-still a lot !
My DVRJapan handle wery well with this SD card...but not GP !
SO i tested with this http://mympx.org/Downloads/p13_sectionid/2/p13_fileid/13
and got this !!!
If I would do this test when I get my SD card from ebay and paid 20£ as for normal original price "not copy" then will send it back ,but thing is I did not use much write speed "only for DVRJapan which need 8000MB/s" ,"30MB/s-sticker and description !!"
so for Gopro is crap and nothing else !
Just beware and test your SD cards after you decide to spend 20/40£ on ebay "buying original SD card" !! it can be bad copy.

So back to test.
Before I start test SD card was formatted in FAT32 ,all default options ,as factory then run test :.
Got that :.
Warning: Only 7559 of 7560 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 13.8 MByte/s
Reading speed: 15.5 MByte/s
H2testw v1.4

so half of write/read speed as in description..at least is 8GB here 
and here is my original 30MB/s* SDHC HD Extreme Video

For information there is "  *   " where 30MB/s * so half of those it's bit to much !!

I only ever buy my SD cards from Amazon (I have amazon prime) or mymemory.co.uk
I run a 8GB Integral UltimaPro C10 20MB/s on my GoPro and it's never been a problem

Seems to be fine with my SD card but why I got half of those read/write speeds ?? connected directly to my samsung SD cars slot.

the 30MB/s is a little misleading on your card as a class 10 card means 10MB/s read or write.  And your test reults confirm that, so you have a class 10 card.  I have a class 10card 32GB card and just ran your test and got very similar results, and have no problems with my gopro2 wth 1080p

I just tested mine, I got 14 MB/S write and 17MB/S read, I'm happy with that as its quoted up to 20MB/S

MicroSD class 10 here with write speed 16mb/s and read speed of 20mb/s.

I got one from picture and tested with 3 different softwares now !! similar results ,also check is all marks,buils quality is as original not copy and I did not found any suspicious things in that card.
Just made gopro update and now it's even worst... sending back gopro as it's faulty.
Just read about that issue and it's quite often "gopro freeze" ,some guys got weak SD cards buy other half just got gopro fault !
