SSD Performance HD Tach
HD Tach
HD Tach is a physical performance hard drive test that uses a special kernel mode VXD to get maximum accuracy by bypassing the file system.
We look at average (not peak!) write performance in this test. In addition to sequential read performance, HD Tach tests the drive's random access time. Random access is the true measure of seek speed. Many drives advertise sub 10 millisecond seek speeds.
HD Tach might be dated software but is visualized TLC/QLC write holes really well.
