I currently run three hard drives, 500gb F3 OS, 1tb F3 files, 1.5tb WD green backup.
NCQ (if a server)
Automatic detection of connected drives (though can be finicky)
Hotswapping via safely remove hardware
Needed for TRIM and garbage collection with some SSD's
NCQ (if a desktop)
Needs drivers so aside from W7 there are often issues with various other bootCD's and tools
Controllers a few years old often have issues with SATA ODD's
You can have the same hotswapping with hotswap.exe (and it's safer too) so I only suggest it if it's needed for a SSD.
