#1= Samsung Spinpoint F3 1TB is the fastest hard drive available in terms of reads/writes. Average speeds hit around 110-130mbps read, and around 110mbps~ write.
#2= Surprise surprise, Samsung Spinpoint F3 500gb... Same as the 1TB, but second to it. 120 mbs read/105 writes.
Unfortunately some of the favorite retailers/etailers do not carry the samsung F3 500gb or 1tb versions.
Newegg is sold out for both the 500gb/1TB HDD's.
$66.14 for the 500gb@ Amazon
$94.99 for the 1TB@ ZipZoomFly supposedly has a $15 mail in rebate leaving it $80.
