CrystalDiskMark: A Disk Benchmark Software for Windows

CrystalDiskMark measures sequential and random read/write speeds of hard drives, SSDs, USB drives, and memory cards, making it a valuable tool for assessing storage performance.

What is CrystalDiskMark?

CrystalDiskMark is a popular disk benchmark software program for Windows. It is used to measure the sequential and random read/write speeds of storage devices like hard drives, SSDs, USB flash drives, SD cards, etc.

Some key features of CrystalDiskMark:

  • Measures sequential and random read/write speeds in MB/s
  • Tests with data block sizes from 512KB to 64MB
  • Supports internal and external drives
  • Graphs performance over time during test
  • Free and open source software

CrystalDiskMark is useful for testing the real-world performance of storage devices. It helps compare drives to see if one meets speed requirements or identifies performance issues. The random read/write tests simulate normal usage better than pure sequential tests.

Overall, CrystalDiskMark is a versatile and reliable disk benchmark utility for those looking to quantify storage device performance for upgrades or troubleshooting.
