I am planning on using solid state disks with my CentOS 5.x systems. Currently, I am using EXT3 for the file system.

From what I can find, CentOS 5.x does not support TRIM

on solid state disks? Is this correct?

Should I obtain and build the updated hdparm and use that to trim my drives (for example, via CRON every night at midnight)? Or should I get fstrim (updated util-linux)?

Any other suggestions on solid state drives (other than noatime on mounts).

Thanks, -- Wade Hampton
