Crystal Disk Mark Tests
In CDM we see the performance of the Rage at different block sizes and queue depths. USB doesn't actually take advantage of native command queuing, so those tests are lost in this review, but we still have 512 and 4K sizes to pick over.
The read 512 speed is very good and runs at the sequential speed. The write speeds really take a hit, though. Here we see performance start to drop off rather quickly.
