Alex Schepeljanski of Alex Intelligent Software develops the free AS SSD Benchmark utility for testing storage devices. The AS SSD Benchmark tests sequential read and write speeds, input/output operational performance, and response times. Because this software receives frequent updates, Benchmark Reviews recommends that you compare results only within the same version family.
Compared below are the Seagate Barracuda XT ST33000651AS (five-platter) and new Seagate Barracuda ST3000DM001 (three-platter). Both drives received AS SSD's sequential benchmark tests, using the same Intel P67 SATA 6Gb/s interface. The older Seagate Barracuda XT ST33000651AS posted 157 MB/s reads followed by 157 MB/s sequential writes, while the new Seagate Barracuda ST3000DM001 improved read speeds to 167 MB/s with slower writes at 147 MB/s. Comparing the results, the old five-platter drive maintained a steady 157 MB/s read/write speed, while the new three-platter drive boosted reads by 10 MB/s but dropped write speed by the same amount.
My assessment: It's a draw, with an advantage point to the new Barracuda ST3000DM001 for boosting speed where it matters most.
