HD Tune Pro 4.01 READ / WRITE Drive Benchmark	Source: HD TUNE

HD Tune Pro is an extended version of HD Tune which includes many new features such as: write benchmark, secure erasing, AAM setting, folder usage view, disk monitor, command line parameters and file benchmark. The benchmark measures raw performance in a couple different ways to measure a hard drive for Read and Write tests, which are conducted separately. To read the results below consider that highest minimum/maximum/average transfer rates are better, while lower (quicker) access times are best. Lastly, highest burst rates are better.

HD Tune 4.01 - Read Tests Read Average Transfer Rate: (MB/s) Points Ranking Western Digital 1TB WD1001FALS HDD 86.1 Western Digital 1TB WD1001FALS HDD (RAID 0) 165.1 Western Digital 1TB WD1001FALS HDD (RAID 1) 86 OCZ Vertex 2 128GB SSD 233.1 Plextor PX-128M1S SSD 100.1 Seagate 2TB Barracuda XT HDD 110.2 Seagate 500GB Momentus XT SSHD 84 Read Access Time: (ms) Points Ranking Western Digital 1TB WD1001FALS HDD 12.2 Western Digital 1TB WD1001FALS HDD (RAID 0) 10.1 Western Digital 1TB WD1001FALS HDD (RAID 1) 10.2 OCZ Vertex 2 128GB SSD 0.056 Plextor PX-128M1S SSD 0.3 Seagate 2TB Barracuda XT HDD 17.2 Seagate 500GB Momentus XT SSHD 16.9 Read Burst Rate: (MB/s) Points Ranking Western Digital 1TB WD1001FALS HDD 134.4 Western Digital 1TB WD1001FALS HDD (RAID 0) 143.6 Western Digital 1TB WD1001FALS HDD (RAID 1) 144.7 OCZ Vertex 2 128GB SSD 216.8 Plextor PX-128M1S SSD 101 Seagate 2TB Barracuda XT HDD 138.9 Seagate 500GB Momentus XT SSHD 183.5

In HDTune, the SATA II 500GB Seagate Momentus XT drive achieves a Read Burst Rate of 183.5 MB/s. Average Read transfer rate is 84 MB/s while Access time sits at 16.9ms. The Momentus XT's Read burst rate is quite good compared to the inexpensive Plextor SSD, but far behind the performance oriented OCZ Vertex 2 SSD.

Next, HD Tune Pro write tests.

HD Tune 4.01 - Write Tests Write Average Transfer Rate: (MB/s) Points Ranking Western Digital 1TB WD1001FALS HDD 85.4 Western Digital 1TB WD1001FALS HDD (RAID 0) 161.9 Western Digital 1TB WD1001FALS HDD (RAID 1) 83.5 OCZ Vertex 2 128GB SSD 215.4 Plextor PX-128M1S SSD 73.4 Seagate 2TB Barracuda XT HDD 105.1 Seagate 500GB Momentus XT SSHD 80.9 Write Access Time: (ms) Points Ranking Seagate 500GB Momentus XT SSHD 9.05 Write Burst Rate: (MB/s) Points Ranking Seagate 500GB Momentus XT SSHD 177.4

HDTune's Write Benchmark slots the 500GB Seagate Momentus XT into a similar position - better than the Plextor, but far behind the Vertex 2 SSD. Write Transfer Rate sits at 80.9MB/s, access time at 9.05 seconds and Write Burst Rate 117.4 MB/s.
