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 2TB Samsung
SSD 970 EVO Plus drives put up the best sequential transfers of the bunch and competitive 4K transfers throughout, though it never quite caught the 1TB drive.
