Does a SSD drive need a special filesystem and/ or
mount options?
If you want to use all features - yes:
- You are restricted to ext4 and btrfs for the moment as they are the
only file systems that can issue the TRIM command
- you have to run the SATA controller in AHCI mode to be able to support
TRIM (and NCQ etc.)
- you should align your partitions to the block size of the SSD and
- tell your FS that it is running on a SSD ('ssd' mount option for
btrfs, don't know about ext4).
Of course you use your SSD as you would do with a HDD, but the
performance will degrade.
