ATTO Disk Benchmark Results
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.
While AS-SSD Benchmark is great for obtaining operational IOPS performance at the 4KB level using 64-threads, ATTO Disk Benchmark works equally well at illustrating bandwidth speeds at various file chunk sizes (including 4KB). Benchmark Reviews has tested the Super Talent USB-3.0 RAIDDrive ST3U64SRK using a queue depth set to 4 for all benchmark runs, each using either the Intel ICH10 USB-2.0, NEC 3.0, or Super Talent enhanced SCSI USB-3.0 driver.
The first test utilized the Intel ICH10 HiSpeed USB-2.0 controller, and produced a 35 MB/s maximum read speed and 28 MB/s write speed; both which plateau at 64-8192 KB.
Next, the Super Talent RAIDDrive was connected to the NEC-D720200F1 SuperSpeed USB-3.0 controller using the NEC driver. The 'standard' USB-3.0 connection delivered 168 MB/s peak read speeds, and a 69 MB/s maximum write speed. These speeds are nowhere near the manufacturers suggested maximum speeds of 320/180 MB/s, so we applied Super Talent's RAIDDrive RAID-0 software and re-tested.
Once the 'STT USB Composite Device' and 'STT USB 3.0 Miniport' software has been installed, the Super Talent USB-3.0 RAIDDrive operates in a RAID-0 twin SSD array. This raised our bandwidth speed results to 239 MB/s maximum read and 106 MB/s peak write performance.
ATTO Disk Benchmark confirms our results with AS-SSD Benchmark, and demonstrates how well the Super Talent RAIDDrive operates on the SuperSpeed USB-3.0 interface compared to the previous generation. Unfortunately, Super Talent appears optimistic in their assertion of a 320/180 MB/s maximum speed. The best results we could produce were 239/106.
