SubjectRe: file system for solid state disks
Hi,

It's important to note that disk-replacement type SSDs perform much
better with very small block operations, generally 512 bytes. So the
lower your file system block size, the better -- this will be the single
most significant performance tweak one should do. This is true for the
benchmarks I've seen where the difference between 4KB and 512Byte block
sizes was almost 100%. YMMV -- always benchmark.

On SSDs which contain built in wear leveling, pretty much any file
system can be used. For SSDs that lack such low level housekeeping,
use stuff like JFFS2.
