Summarizing our benchmark results, the Toshiba HG6 256GB returned average sequential reading speeds of 516 MB/s and sequential writing speeds of 484 MB/s, consistent to the figures quoted by Toshiba and regardless of whether the data was compressible or not. The drive was also pretty fast in reading of 4k and up to 8MB block sizes (ATTO), while writing of the same files was also good but not the fastest we have seen from an SSD.

In the random read tests, the Toshiba HG6 256GB SSD remained within the standards set by the competition in the 4K and 512KB read/write benchmarks, and showed its strength in the random reads of small 4K files in increased queue depths. The drive's performance in the random writing tests of 4K QD32 was above the average.

Overall IOPS performance was excellent in a 100% random, 67%-33% read/write distribution benchmark.

The Toshiba HG6 is a solid state drive that will offer you well-balanced performance with both incompressible and compressible data streams. It is not the fastest SSD around as it faces the strong competition in the highly-populated SSD market, but besides performance, it comes with benefits such as Toshiba's 19nm Toshiba Toggle Mode MLC NAND and a good price -- about £145 ($130) for the 256GB version.
