Toshiba OCZ RD400 512GB M.2 PCIe SSD

3. ATTO Disk Benchmark

We start with the ATTO Disk Benchmark. The tool measures storage systems performance with various transfer sizes and test lengths for reads and writes. The benchmark performs file transfers ranging from 0.5 KB to 8192 KB. ATTO can be adjusted to do overlapped I/O, in a variety of queue depths. The test was run with the default runs of 0.5KB through 8MB transfer sizes with the total length being 256MB and QD4. ATTO probably gives the most accurate results for compressible read and write data:

The RD400 smashed any competition in the ATTO benchmark, The SSD's write speed topped at about 1633 MB/s with 2MB files and at 2710MB/s for write. The performance was also very high with small 4KB files.

Compared with the Samsung 950 Pro SSD, the Toshiba RD400 was faster in both the read and write tasks, no matter the size of the files used. Obviously the RD400 has been optimized to perform very fast in the specific benchmark
