CrystalDiskMark is a useful drive benchmarking utility that measures sequential read and write performance at various sizes and random read and write performance at various sizes. It allows users to gain a surface-level understanding of drive performance similar to those found on product retail packaging.
In the default 1GB random test, sequential read performance closely approaches the 600MB/s limitation of the SATA III interface, and both sequential read (564.5MB/s) and sequential write (537.3MB/s) performance actually surpass OCZ’s Trion 150 480GB product specs of 550MB/s reads and 530MB/s writes.
In the 1GB 0Fill test, all numbers are mostly the same as above with the exception of a noticeable ~113MB/s increase in 4K random read performance and a ~57MB/s increase in 4K random read performance at QD32.
