Hi, I have just bought a Sandisk 64gb Extreme Pro SDXC Card 95mb/s card from ebay, on Amazon they are currently £75 and i paid £43.

I got it from this link:

http://www.ebay.co.uk/itm/171559999560?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Of cause it says its genuine and that they are a authorised sandisk reseller, but when i get it how will i know its actually a real one?

They are listed as accepting returns etc so if it turns out to be fake i'd like to know how i can look at the card to know its a fake to get my money back.

Of cause it may be real, which would be great :)

Any help would be great

regards

James
 
I had a genuine card so used that to take rapid fire pictures on my Canon 40D. The original one could take 12 RAW shots but the new card could only take 4 before it started to stall.

Not a great help if you've not got a pukka card but still useful to know I guess :)
 
My pro card hits 80MB/s on usb3 file transfers
It's capacity is correct (by adding that much data to it)

That satisfied me.

What made me query it before was using usb2 reader I only got 20MB which doesn't seem to saturate usb2 technically but in reality it was. I think someone said many(all) USB2 card readers saturate here

My card reader was a cheap one off eBay but absolutely hits usb3 speeds especially with my SanDisk extreme 64 USB stick
 
Make sure you get a decent USB 3 reader if you want the maximum speed. I just bought the Lexmark USB 3 reader and it seems to get faster speeds than the little cheapy one I had before.

The first one I had was about £8-9 or something and this is a Transcend one. The new one is a Lexmark one that was on sale for £15 and I'm sure the speed is better although I can't say I've tested it...

The Transcend one used to periodically lose connection and then reconnect moments later for no reason :/ maybe it's faulty but who knows. Quite happy with the new one :)
 
I got the card finally, run into one little snag with it, it shows up fine in my slr camera but when i connect it to my windows 7 64bit laptop it constantly keeps asking me to format the card, when i do it says it cant complete wheh formatting it as exfat but does format if i do it as ntfs, my camera uses exfat and works fine when i format it in camera.

anyway i run a speed test with h2testw and the speed was 72mb.

I have one card which often asks me to check for errors when I put it in my PC and one that doesn't. It never actually has to fix anything and the files are fine etc so it's a bit weird.
