AmorphousDiskMark2.5.1

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

Features

• 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 or IOPS scores in the main window
• Read/write MB/s and IOPS scores in the tooltip
• Test data: random or zero
• Test size: 16 MiB, 32 MiB, 64 MiB, 128 MiB, 256 MiB, 512 MiB, 1 GiB, 2 GiB, 4 GiB, 8 GiB, 16 GiB, 32 GiB, or 64 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.
