CrystalDiskMark is a synthetic benchmark that tests both sequential and random small and mid-sized file transfers using incompressible data. It provides a quick look at best and worst case scenarios with regard to SSD performance, best case being larger sequential transfers and worse case being small, random transfers.

The Toshiba XG5 didn't lead the pack in any particular category here, but it offered competitive performance nonetheless. Reads were always competitive, but the XG5 actually had the best sequential write performance at QD32 and it tied for the pole position in the same write test at QD1. 4K transfers weren't the best, but again, they were competitive with the other drives we tested.
