Theodore Ts'o's blog post is somewhat misleading, as even that manufacturer's MLC SSDs have an erase block size of 512KiB (PDF), like OCZ's drives - not 128KiB. You're better off running fdisk -H 32 -S 32 /dev/sda, which will align partitions to 512KiB, and mke2fs -b 4096 -E stride=128,stripe-width=128 -t ext4 (128 * 4096B = 512KiB).
for partitioning see http://www.ocztechnologyforum.com/forum ... sing-fdisk
But without ATA TRIM your drive writes will decrease (depending on write usage)
The only solution seams to secure erase the whole drive and do a reinstall
* add "elevator=noop" to /boot/grub/menu.lst
Some tips i found but think this came from a myth:
* use a tempdir for logs
/etc/fstab
tmpfs /var/log tmpfs defaults,noatime,mode=0755 0 0
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
tmpfs /var/tmp tmpfs defaults,noatime,mode=1777 0 0
/etc/rc.local
for dir in apparmor apt ConsoleKit cups dist-upgrade fsck installer news samba unattended-upgrades; do
mkdir -p /var/log/$dir
done
* Set Firefox Cache to RAM
in about:config set browser.cache.disk.enable to false
* change the file system mount options on SSDs to "noatime"
