Fitted my PC with a 256G Crucial M4 and its a very good drive - running Win 7.

I need to update to the latest firmware still but it boots fast and unlike other HD's hasnt slowed down at all.

Opening Outlook with a lot emails used to take a few seconds or more - too long for me, now its instant as is opening most prgrammes.

However its a lot of cash for a miminal gain if you look at it from one angle, but its not a minimal gain overall.

Very happy with mine
