RMA Voyager GT Peformance

Recommended Posts

Hi,

 

I've always been impressed by the performances from my Voyager GT 2GB. So I decided to buy the 16GB version but it gives me disappointingly bad Write performances (see below). Is it the nominal performance of the 16GB version or should I send the key to Corsair for a replacement?

I would try the SD Card.org Flash Format utility on the 16 Gig drive then run the test again.

But the older FV 2.0 GT drives used SLC Flash and drives above 8 Gig have to use MLC Flash which is slower but I would expert the write to be a bit better.

Since you just got the drive you can check with the reseller and see if they will let you exchange itr for the Flash Voyager 3.0 GT 16 Gig which would be 2-3 times faster than your 2.0 Gig Flash voyager.
