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.
DiskSpd is a free and open-source [2] command-line tool for storage benchmarking on Microsoft Windows that generates a variety of requests against computer files, partitions or storage devices and presents collected statistics as text in the command-line interface or as an XML file.

IOzone is a file system benchmark utility. [1] [2] Originally made by William Norcott, further enhanced by Don Capps and others. Source code is available from iozone.org. It does mmap() file I/O and uses POSIX Threads. It won the 2007 Infoworld Bossie Awards for Best file I/O tool. [3] [4] The Windows version of IOzone uses Cygwin.
Drives remain operable during self-test, unless a "captive" option (ATA only) is requested. [104] The self-test logs for SCSI and ATA drives are slightly different. The ATA drive's self-test log can contain up to 21 read-only entries. When the log is filled, old entries are removed. [112]
CPU-Z is more comprehensive in virtually all areas compared to the tools provided in the Windows to identify various hardware components, and thus assists in identifying certain components without the need of opening the case; particularly the core revision and RAM clock rate. It also provides information on the system's GPU.

The first HDD [11] had an average seek time of about 600 ms. [12] and by the middle 1970s, HDDs were available with seek times of about 25 ms. [13]Some early PC drives used a stepper motor to move the heads, and as a result had seek times as slow as 80–120 ms, but this was quickly improved by voice coil type actuation in the 1980s, reducing seek times to around 20 ms.
