Test Method

We tested the CompactFlash cards with a Pretec USB 3.0 Card Reader and CrystalDiskMark 3.0 x64. The software ran five 1000MB write- and readtests on the product. We noted the fastest results. Results can differ per computer, so we use the same hard- and software on every test. The fastest results on our system, will be the fastest on yours as well.

1GB is normally 1.024MB. Vendors however, count 1GB as 1.000MB. We count the same way vendors do.
