SCSI hard drive

YAAAAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!!!!!!!!!!!!!My dad brought me an old hard drive from his work. I really need it because with all the photo's I take, I've used up 7.5 gb of my 8 gb hard drive. The hard drive he gave me is a 36.7 gb hard drive.............Most importantly, its a SCSI(scuzzy) hard drive.......Whats so great about them? They cost two or three times the price of a hard drive the same size. Why? Because they have a much faster data transfer rate than a normal hard drive. Now I just have to get the right cables so I can use it.
