A trim command (known as TRIM in the ATA command set, and UNMAP in the SCSI command set) allows an operating system to inform a solid-state drive (SSD) which blocks of data are no longer considered to be "in use" and therefore can be erased internally. [1] Trim was introduced soon after SSDs were introduced.
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. [3] [4] [1]
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 Windows System Assessment Tool (WinSAT) is a module of Microsoft Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows 10, and Windows 11 that is available in the Control Panel under Performance Information and Tools (except in Windows 8.1, Windows 10, and Windows 11). It measures various performance characteristics and capabilities of ...

According to Scott Hanselman of Microsoft, Windows 7 [verification needed] and later do defragment a solid-state disk (SSD) but in a completely different way. There is less incentive for defragmentation of SSDs because file fragmentation has less performance impact on them and they handle a finite number of storage cycles before their lifespan ...
The peak random write performance on an SSD is driven by plenty of free blocks after the SSD is completely garbage collected, secure erased, 100% TRIMed, or newly installed. The maximum speed will depend upon the number of parallel flash channels connected to the SSD controller, the efficiency of the firmware, and the speed of the flash memory ...
Prior to version 7, Microsoft Windows did not take any specific measures to support solid state drives. From Windows 7, the standard NTFS file system provides support for the TRIM command. [198] By default, Windows 7 and newer versions execute TRIM commands automatically if the device is detected to be a solid-state drive.
