PATA, SATA and ATA
- Parallel ATA (PATA) is just the new name given to plain old ATA when Serial ATA arrived. Under Linux it seems PATA drivers can be used with the new libata library, so you should be able to use PATA.
- SCSI disk support is needed in the Linux kernel in order to make SATA disks work correctly.
AHCI
With SATA drives the AHCI driver can be better than other (native) drivers since it implements NCQs. So use AHCI whenever you can. This option usually is present in the BIOS as well.
