Why does Intel SSD Toolbox need to schedule a TRIM on a daily or weekly basis if the underlying SSD supports the TRIM command? Shouldn't the drive TRIM in real-time without this tool? Is this tool made for users whose motherboard and/or operating-system block the TRIM command from reaching the SSD?
It is for operating systems that do not themselves support TRIM, like XP and Vista, who don't send the TRIM command. With Windows 7 windows itself sends the TRIM command every time something is deleted.
If something is blocking the TRIM command (like the drive being in an RAID array) this Toolbox will not overcome that.
