AmorphousDiskMark measures storage read/write performance in MB/s and IOPS.

  • Sequential 128 KiB block read/write tests with Queue Depth=1, 2, 4, 8, 16, 32, 64, 128, 256, 512, or 1024
  • Random sequence 4 KiB block read/write tests with Queue Depth=1, 2, 4, 8, 16, 32, 64, 128, 256, 512, or 1024
  • Sequential 1 MiB block read/write tests
  • Random sequence 4 KiB block read/write tests
  • Read/write MB/s scores
  • Read/write IOPS scores in tooltip
  • Test data: random or zero
  • Test size: 50 MiB, 100 MiB, 500 MiB, 1 GiB, 2 GiB, 4 GiB, 8 GiB, 16 GiB, or 32 GiB
  • Test interval: 0 seconds, ..., 10 minutes

NOTE: Please do not repeat the read/write tests unnecessarily. Repeating read/write tests may shorten the lifespan of your storage device.


MB/s: megabytes per second: 1,000,000 bytes per second

IOPS: input/output operations per second

KiB: Kibibytes: 1,024 bytes

MiB: Mebibytes: 1,024 x 1,024 bytes: 1,048,576 bytes

GiB: Gibibytes: 1,024 x 1,024 x 1,024 bytes: 1,073,741,824 bytes
