CrystalDiskMark 3.0.1 Results

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.

Here, the SanDisk Ultra Plus impressed with its high sequential read speeds and it was on a par with the very quick SanDisk Extreme, but its performance dipped noticeably when it came to handling small data blocks. Having just four independent NAND channels has undoubtedly boosted its performance in handling contiguous data, but hampered its ability to handle multiple small data blocks. Again, the SanDisk Ultra Plus easily breezed past the older Plextor M2S, despite having an inferior controller.



The Good
Fast sequential read and write performance
Bumper to convert drive to 9.5mm form factor
The Bad
Below average random access performance
No HDD installation bracket or other accessories
Extremely expensive; top performing drives retail for much less
