Recently I built my new computer set, and I installed a Intel 330 120GB SSD as my OS drive.
I was reminded by many to make sure TRIM command has been enabled to prevent SSD performance degrade, as of many search and report, TRIM was suppose to be enabled by default on Windows 7, anyway just to be sure.

DisableDeleteNotify = 0 (enabled)
