None of them really needs it, but every little bit of wear reduction
helps. TRIM is a SATA-only (and perhaps PCI) command. So Firewire,
USB, etc, disks have to live without it. SandForce compresses data
and that reduces wear for users with compressible stuff (probably
most people). More into is here -
