Yes that is true, if the OS supports TRIM, just leaving about 20% unused should provide the same results. However I have found TRIM support on linux to be a bit spotty, depending on the distribution, kernel, filesystem, etc.
I've just had very poor performance on BTRFS filesystems mounted with the "discard" option using a 120G Intel SSD known as "INTEL SSDSC2CT12 300i". Turning off the discard option at the suggestion of a member of the BTRFS list improved performance by more than a factor of 8! Apparently the problem is that TRIM is a non-queuing command so it blocks everything else. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
