I have an UltraDMA Maxtor HDD 40 gig right now and it is 8 yrs old. I wanted to know how it compares to IDE and SATA drives, is this before those types of HDDs or is it a part of those HDDs/
UltraDMA is basically IDE. WD Black drives are a bit overpriced, rather get the Blue series if you're buying. HDDs only recently caught up to IDE's 133mB/s limit but SATA drives have better burst rates which can make a difference.
