I'm in the same boat. Shopping for a 1tb sata 3.5" drive. I was leaning towards a Caviar Black, but I'm looking at Samsung drives also, particualarly the HD103SJ. Anyone have any opinions? It will be my main drive in my system and my cheap P45 board doesn't support raid, so speed and reliablity are my priorities.
Edit: This review is missing a 1tb Caviar Black drive, but the 1tb F3 numbers look good.
The Black is a better drive for an OS and the F3 is better for storage. The benchmarks that I have seen show that the Black works with multitasking and app opening better and the F3 is faster in transfer speeds.
