   CrystalDiskMark is an open source disk drive benchmark tool for Microsoft Windows from Crystal Dew World. Based on Microsoft's MIT-licensed Diskspd tool, [2] this graphical benchmark is commonly used for testing the performance of solid-state storage. [3] [4] It works by reading and writing through the filesystem in a volume-dependent way.

   The disk drives would measure the disk's "health parameters", and the values would be transferred to the operating system and user-space monitoring software. Each disk drive vendor was free to decide which parameters were to be included for monitoring, and what their thresholds should be. The unification was at the protocol level with the host.

7. Hard disk drive performance characteristics - Wikipedia

   Some SATA II and later hard disk drives support staggered spin-up, allowing the computer to spin up the drives in sequence to reduce load on the power supply when booting. [44] Most hard disk drives today support some form of power management which uses a number of specific power modes that save energy by reducing performance.
