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.
AIDA64 leaps forwards by adding a collection of 64 bits processor and memory benchmarks, an optimized ZLib data compression and an enhanced set of fractal computational floating-point benchmarks, a new CPU benchmark method to determine cryptographic hash value calculation performance, support for SSDs (SSD specific SMART entries, etc.) and ...

A drive that implements S.M.A.R.T. may optionally implement a number of self-test or maintenance routines, and the results of the tests are kept in the self-test log. The self-test routines may be used to detect any unreadable sectors on the disk, so that they may be restored from back-up sources (for example, from other disks in a RAID). This ...
Windows Media Encoding Performance; CPU Performance; Memory Performance; Disk Performance (includes devices such as Solid-state drives) While running, the tests show only a progress bar and a "working" background animation. Aero Glass is deactivated on Windows Vista and Windows 7 during testing so the tool can properly assess the graphics card ...
Performance profiler (sampled or instrumented) and analyzer, focused on game development. Proprietary Systemtap: Linux Programmable system tracing/probing tool; may be scripted to generate time- or performance-counter- or function-based profiles of the kernel and/or its userspace. Open source Valgrind: Linux, macOS, Solaris, Android
A scalable block layer for high-performance SSD storage, known as blk-multiqueue or blk-mq and developed primarily by Fusion-io engineers, was merged into the Linux kernel mainline in kernel version 3.13, released on 19 January 2014. This leverages the performance offered by SSDs and NVMe by allowing much higher I/O submission rates.
SpinRite is claimed by its developer to have certain unique features, [4] such as disabling of disk write caching, disabling of auto-relocation, compatibility with disk compression, identification of the "data-to-flux-reversal encoder-decoder" used in a drive, and separate testing of buffered and unbuffered disk read performance, and direct ...
