Sandisk has updated its Extreme Pro to 95MB/s speed and at the same time finally to speed class 10, which the old 45MB/s model is not. Both are naturally class U1. This is clearly the fastest SDHC UHS-I card so far when it comes to benchmarks that I have seen on some blogs and done myself. It is fastest in continious read and write and especially fast in random operations. I have the 95MB/s Delkin/Toshiba 633x to compare and Sandisk is the clear winner. PRO: - fastest in UHS-I devices - fastest in non-UHS devices - fastest in random operations -… Read more
This is a small and light USB 3.0 card reader made with Genesys Logic GL3220 controller. It supports 3 types of cards CF, SD and MS., including all variants of these cards up to date.

PRO: - very pocketable for Multi card reader - fastest in my small collection of readers * - good quality of manufacturing for a plastic construction - drive bays are good (at least for SD and CF no MS to try) and on the front side for me - reads and… Read more
Bought this card to have a fast card to upload my pictures and to test my USB 3.0 reader(s) and PCI-e host card. I only have PCI-e v.1 but it seems fast enough. Popular and somewhat optimistic Crystal Diskmark 3 gives read/write speeds of 94.8/22.9 MB/s with i-tec USB 3.0 reader. This is well in line with the product spec's 90/25 'up to' numbers.
The known health test programme H2testw gives readings 78.1R/19.4W for Panasonic and 39.0/30.0 for Sandisk to compare. This gives a good picture of the nature of these cards.
I have a Pretec i-Disk II SDXC reader (USB 2.0) which has been fastest to read/write Sandisk Extreme HD video 30 MB/s SDHC cards with USB 2.0. I used… Read more
