"The performance in benchmarks was impressive. When used in SATA150 mode, the 7K500 managed to score better than the competition in just about every phase of testing. Enabling SATA300 mode ramped up the performance slightly in most tests, and the burst speed reported in HD Tach was quite impressive as it popped up to 223 MB/s! Overall, I was expecting higher scores across the board, but the testing turned into an educational experience for me, as I learned exactly what the test system and SATA300 could do for me."
