Windows, SSDs, TRIM, and scheduled TRIM

OK, it's my understanding that if you have an SSD on Windows 7 and/or 8, you should check this at the command line...

fsutil.exe behavior query DisableDeleteNotify

And make sure that the value is 0.

Do you actually need to do scheduled TRIMs of the SSD or does Windows internally do the process of activating the ATA TRIM command as you use the machine normally? Does it send the ATA TRIM command when you delete files automatically?

Do you even need to schedule a dedicated TRIM command using say, the Intel SSD Toolkit? Or is it something that you don't need to worry about?

'Delete Notify' means sending a TRIM when clusters are freed, i.e., as files are deleted.

(and not disabling delete notify means it's enabled: a curse on people who code negative options).

So, set DisableDeleteNotify to 0 and forget about it.

So then what's the use of the Intel SSD Toolkit other than possible firmware updates?

Guessing:

1. To do all that other stuff it does.

2. To allow you to screw around with the drive for maintenance purposes.

3. To allow the use of Intel SSDs on systems that don't know how to TRIM (e.g., XP).

correct, especially on XP.
