The Samsung SP2504C hard disk drive is a 250GB SATA 300 monster. It is on test at Hardwaresecrets. It has a relatively small buffer - 8MB, a 7200rpm rotational speed, support for NCQ, two 125GB platters. This Samsung is one of the fastest out there - it hasn't been compared directly to the Raptor yet to my knowledge. It is 75% faster than the Maxton Diamondmax 16 250GB, which is a contemporary model. FYI, they were using Diskspeed32 as benchmarks tool. It is more expensive than most, but it is worth it.
