ATTO Disk Benchmark

The ATTO Disk Benchmark program is free and offers a comprehensive set of test variables to work with. In terms of disk performance, it measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. There are some minor improvements made to the 2.46 version of the program that allow for test lengths up to 2GB, but all of our benchmarks are conducted with 256MB total length. ATTO Disk Benchmark requires that an active partition be set on the drive being tested. Please consider the results displayed by this benchmark to be basic bandwidth speed performance indicators.

Seagate Momentus XT 750GB Solid State Hybrid Drive

RAID-0 Seagate Momentus XT 750GB Solid State Hybrid Drives

Bandwidth speed tests begin with the Seagate Momentus XT attached to the motherboard's native Intel P67-Express SATA 6Gb/s port. Using the ATTO Disk Benchmark tool, the test drive performs file transfers ranging from 0.5 KB to 8192 KB. After several caching runs followed by restarts, the single 750GB Seagate Momentus XT revealed 115 MBps maximum read speed that plateaus from approximately 8-8192 KB file chunks, and 116 MBps peak write bandwidth plateaus from 32-8192 KB. The chart below illustrates how the Seagate Momentus XT compares:

In the next section we utilize PCMark 7 to test real-world storage performance...
