ATTO is one of the oldest hard drive benchmarks that is still used today. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that you can easily interpret. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.
Benchmark Results: Once again, the OCZ Throttle eSATA drive showed impressive benchmark numbers in the Overlapped I/O benchmark with write speeds hitting 52MB/Sec Write and 87MB/Sec Read.
HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives (ZIP/JAZZ), flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device possible.
Benchmark Results: HD Tach showed the average read speed was 84.3MB/Sec, write speed of 50.3MB/Sec and a burst rate of 1,709.2MB/Sec. Obviously, the burst speed is incorrect, but the average read speed is in line with what we saw on the other three benchmarks. This drive is super fast when run in eSATA mode! The random access time was found to be 0.2ms and the CPU usage was 1% on this benchmark.
