Why TRIM is Important to Solid State Hard Drives

 

Does a person with a TRIM SSD installed on Windows 7 need to do anything special to have TRIM function properly? I've checked with CrystalDisk and also that DOS command, whatever it is, which returns a 0. Both indicate TRIM is functioning properly in my computer. I just use my PC as normal and TRIM works? Can I mess it up under normal computer usage?

I heard somebody say you need to sit at the logon screen for a few minutes each time. I don't have a logon screen (I'm the only user.) and I never turn my PC off.

 

No...however....

There have been instances where leaving System Restore affects TRIM in its proper operation. My advise is to do a Crystal Disk Mark test and then every now and then do another. If your performance slows or degrades over time...consider the reason.

There have been alot of Intels that have seemed to be affected by the way System Restore sets its allocation points. Trim either worked poorly or wasnt working at all as could be seen by the length of time it took to run the Intel Toolbox.

 

I think this is a much better link than the one above. The one above I find actually seems to have inaccurate technical info. Trim does nothing to remove the Block write reality. It's magic is in it's management. The previous link states that in fact allows page writes. That is not my understanding at all. But I am far from an expert on this.

Edit: Wow I started writing and went away and others posted so my post is pre new question and Les.

 

thanks for the link
