Yesterday i found out that if you have a modern SSD and are planning on using RHEL6 or CentOS6 then LVM will not support the "TRIM" ATA command thus there will be a significant decrease in the write perfomnace of the drive with time. Linux swap will use it but the only way to enable this feature is if your partitions are native ext4 and you use the "discard" option. Thus TRIM will not be enabled by a default install except for swap space. mike
