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 WD SiliconEdge-Blue SSD connected to the integrated Marvell SE9128 3rd-Generation SATA-6.0Gbps adapter, as the ATTO Disk Benchmark tools performs file transfers ranging from 0.5 KB to 8192 KB. The 256GB model SSC-D0256SC-2100 reveals 245 MBps maximum read speed that peaks at 128KB and plateaus from 256-8192 KB file chunks, and the 186 MBps peak write bandwidth plateaus from 64-8192 KB. The read-from results are extremely close and the write-to speeds surpass the stated 250/170 MBps maximum specified by Western Digital.


While the WD SiliconEdge-Blue SSD doesn't top our peak-speed bandwidth charts, it easily earns a spot among some of the fastest Solid State Drive products on the market. Based on this information, it appears the JMicron JMF612 processor inside the SiliconEdge-Blue outperforms some of the fastest Indilinx-based SSD.
