Why You Need TRIM For Your SSD

Windows 7 Boot

For this test we use disk imaging software to create an exact copy of the same Windows 7Home Premium install on every hard disk drive or SSD before recording the time taken to boot from the BIOS logo screen to a working Vista desktop, using the Crystal Disk Diskinfo set to run at startup as the chequered flag.

Other than this, all other start-up processes were disabled prior to the imaging process. The boot time was recorded using a standard handheld stopwatch, with the test repeated five times and an average taken from the middle three results to produce the figures below.
