I read here that:
[T]o use TRIM, you need a OS that supports it, such as Windows 7, Mac OS X and some variants of Linux being the only ones as far as I know. You also need a SSD that supports TRIM obviously. Note that OCZ, Intel and a few other SSD manufacturers offer a utility that mimics what TRIM does, for OSes that don’t support TRIM.
My question is whether or not Ubuntu 10.04 LTS authentically supports TRIM?
