hits class 10 speeds easily on the writes.
Over the last several months, I've purchased a variety of 8, 16 and 32gb memory cards and I thought I'd give them a going over with this software. I should note that none of the cards I've purchased have failed, but some do seem very slow compared to others. The 32gb was sold to me as a 4x speed card and both the 16gb cards I have were sold to me as 10x. I didn't have time to test the 32 gig card today but I'll come back and update the review later. This card however was painfully slow so it ended up as a Windows 7 bootable OS disk that I use to install windows.
First the results of this card. The Samsung 16gb 10x. Purchased from "City of memories".
I should note that although the large SD adapter had a Samsung sticker on it, it arrived without any sort of retail package. I know that big manufacturers like Samsung and Kingston don't sell their stuff without retail packages so I was wary right from the start. The actual Mico-SDHC card itself has no branding on it but just basic printing indicating that it's a class 10, etc.
Test results for this card:
Writing speed: 9.07 MByte/s
Reading speed: 17.8 MByte/s
What do the numbers mean? It's difficult to determine if this is indeed 10x/class 10 speed because of a variety of factors involved and as of yet I have not found an internet reference which really gives precise details on what this means.Read more ›

I used this to record a few HD videos at a frame rate of 30fps and they were absolutely fine. The images produced were bang on, clear, vibrant colours with great audio clarity. Shooting pictures with a DSLR was good too. Burst shots, high speed shots and video were all good.
This card picked everything up fine.
If you're looking for a class 10 card then give this one a go, you won't go far wrong.
The card works fine but the claimed read/write speeds by the seller are wildly misleading. After performing repeated benchmark test to verify results, these are the "BEST" results obtained.
Minimum read: 18.1 mb/s
Maximum read: 21.0 mb/s
Average read: 19.9 mb/s
Minimum write: 1.8 mb/s
Maximum write: 3.9 mb/s
Average write: 2.6 mb/s
Access time: 0.7 ms
A you can see "NOWHERE" near claimed performance.
