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 2.34 version of the program, but the benchmark is still limited to non-linear samples up to 256MB. 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.
Our basic bandwidth speed tests begin with the Seagate Momentus-XT connected to the Intel ICH10 controller in AHCI mode, as the ATTO Disk Benchmark tools performs file transfers ranging from 0.5 KB to 8192 KB. The 200GB model we received reveals 108 MBps maximum read speed that plateaus from 8-8192 KB file chunks, and also 108 MBps peak write bandwidth plateaus from 32-8192 KB.
Adaptive Memory Technology Notice
The Seagate Momentus-XT Solid State Hybrid Drive employs a proprietary Adaptive Memory technology that improves application performance matching the highest usage patterns. In most cases, benchmark performance tools do not activate the hybrid SSD features of this storage device.
