CrystalDiskMark is a piece of software that allows you to benchmark your hard drive or solid state drive, the purpose of benchmarking is to make sure that your HDD or SSD is performing optimally. CrystalDiskMark is only available on Windows and can be all major Windows Releases, it even works on Windows 10 Tech Preview.
CrystalDiskMark lets you select any drive that you want and perform a number of tests on them to measure performance for reading and writing. It will run sequential read and write tests as well as random read and write tests and will display the results in MB/s and IOPS.
CrystalDiskMark shows a speed of 564.4MB/s on the Seq Q32T1 test and boasts a write speed of 535MB/s exceeding the vendors specified speed ratings. The 4K Q32T1 test shows 421.4 MB/s Read and 359.3 Write churning out some pretty respectable speeds for a SSD. Sequential testing reveals 522.4MB/s Read and 498.1MB/s which should bolster up sagging performance caused by a HD bottleneck. The 4K testing is more indicative of a server environment writing small bits of data to databases and applications using small read/write transactions. Smaller transaction mean higher IOPS and higher IOPS typically slow things down some and our drive came in at 164.3MB/s Read and 118.8 Write.
