CrystalDiskMark is a handy and practical utility designed to test the performance (random & continuous read/write speed) of your hard drive (HDD/SSD) or other storage devices. In order to identify the performance and quality of them, which is especially suitable for the hard disk newly purchased or used for a long time.

CrystalDiskMark's simple and easy-to-use interface allow you to test your storage devices anytime and anywhere. It runs five times with 1,000 MB data volume each time by default, and extracts the best score from the final results. In addition, you can also customize the number of test runs, test data size, which drive to test, and decide whether testing various performance indicators simultaneously or separately.

Key Features

  • Measure sequential reads/writes speed
  • Measure random 512KB, 4KB, 4KB (Queue Depth=32) reads/writes speed
  • Select test data (Random, 0Fill, 1Fill)
  • Theme support
  • Multi-Language support
  • Support both HDD and SSD
BTW, CrystalDiskMark is also an easy way to detect any possible physical problem on your hard drive.

Prompts

  • "MB/s" means 1,000,000 byte/sec.
  • The result depends on Test File Size, Test File Position, Fragmentation, IDE (PATA)/SATA/RAID/SCSI controller and CPU speed etc…
  • For partial SSD, the result depends on test data (random, 0 fill, 1 fill).
