7,200-RPM terabytes from Hitachi, Samsung, Seagate, and WD face off
 

We're left with Samsung's Spinpoint F3, which is our clear favorite of the four. Not only does the F3 offer the best performance in all manner of sequential transfers, it's easily the quietest of the drives overall. I'm not thrilled by the fact that the F3's transaction rates drop off after 32 concurrent I/O requests, but that's not a condition many desktop users are likely to face. Besides, the Spinpoint certainly held its own in our disk-intensive multitasking tests, which are far more indicative of the sort of workloads produced by enthusiast desktops. Samsung doesn't give up much ground to the Caviar when it comes to random access times, either.
