CrystalDiskMark / Blackmagic Disk Speed Test Downloads

 An SSD speed test is a benchmark used to measure how fast your solid-state drive can read and write data. It evaluates performance to ensure your drive is running at its expected potential.

These tests typically measure two main metrics:

• Sequential Speed: How fast the drive reads or writes large, single files (like moving a 4K movie). It is measured in megabytes per second (MB/s) or gigabytes per second (GB/s).

• Random Speed: How fast the drive handles thousands of small, scattered files (like opening an operating system or launching an app). This is measured in IOPS (Input/Output Operations Per Second) and is often the best indicator of day-to-day responsiveness.

To run a speed test yourself, you can use popular utility tools like CrystalDiskMark (Windows), Blackmagic Disk Speed Test (Mac), or built-in command-line tools like dd (Linux).
