SCSI and now SAS drives are faster and generally have longer warranty. But
they tend to come in smaller capacity per drive.
The choice to spend more for SCSI or SAS depends on the amount of disk IO
you expect. Both SCSI and SAS are used for arrays more where you have a
number of drives. Usually these drives are in hot-swap enclosures.
