CrystalDiskMark is an easy-to-run and quick utility to use to gauge a drive’s performance. It measures sequential read and write performance and random read and write speeds of random 4KB, 4KB (queue depth 32) and 512KB data.
The Transcend SATA III SSD 720 was pretty impressive on CrystalDiskMark, easily matching the fastest competitors in the market today. For most parts, it was on a par with speed kings such as the Intel SSD 520 Series and Kingston Hyper X. However, we observed that it was noticeably slower on the 4K, 32 requests queue depth run when compared against the Intel drive. Elsewhere, it had some of the highest read speeds for 4K and 512K blocks.
