Hm well with a Samsung drive you won't need an extra cable; at least not with proper enclosure like i have. Works perfectly with one cable. Very convenient to more 100GB along. :) > I imagine you could get 30W from 12 dedicated USB ports > :-) Well a typical motherboard has only 2 or 3 USB controllers (reaching a total of 6 ports). So you would need some 5 PCI USB controllers to get those 12 "dedicated ports". ;-) USB is not really meant for these power ratings... >> > drives and I prefer using Seagate drives inside. >> >> Seagate gets rather hot; Samsung is a lot better in that respect. > > I have a Sarotech Hardbox enclosure for 3.5" > > That's what I'm saying, Seagate is hot! But seriously, > fanless enclosures are a problem with any drive. With a 2,5" Samsung drive you won't have any problems with heat; these drives do 0,6W; very power-efficient i would say. > Hmm, Samsung 3,5" drives are rather cheap these days, > look like a bargain to me.

The Samsung T166 500GB drive not only has the highest GB-per-euro/dollar ratio but is also the fastest drive in terms of Sequential Transfer Rate (STR); beating even the WD Raptor; though i have to say random I/O performance is much more important than STR. - Veronica
