HD Tach provides only two results, the burst transfer rate and the average transfer rate. We ran the “long bench” test from this program.

On the burst transfer rate measured by HD Tach Seagate Barracuda 7200.11 (ST31000333AS), Seagate Pipeline HD Pro, Seagate SV35.3, Seagate Barracuda ES.2 and Seagate Barracuda 7200.11  (ST31000340AS) achieved the best performance level. They were, on average, 3.92% faster than Samsung Spinpoint F1, 5.38% faster than Western Digital Caviar Green, 5.56% faster than Samsung Eco Geen F2, 7.35% faster than Seagate Barracuda LP, 8.24% faster than Western Digital Caviar Black, 8.29% faster than Western Digital RE3 and 11.32% faster than Seagate Barracuda 7200.12.

Average transfer is certainly the most important parameter for the regular PC user and on HD Tach Seagate Barracuda 7200.12 was the best performer, being 14.60% faster than Seagate Barracuda 7200.11 (ST31000333AS), 14.72% faster than Samsung Spinpoint F1 and 18.17% faster than Western Digital Caviar Black. Against the “green” models, it was 12.37% faster than Seagate Barracuda LP, 23.76% faster than Samsung Eco Green F2 and 39.29% faster than Western Digital Caviar Green.

On the enterprise arena, Western Digital RE3 was 6.32% faster than Seagate Barracuda ES.2.
