Toshiba HG6 256GB SSD Review

The Toshiba HG6 is a balanced, high performance solid state drive, designed to deal with both incompressible and compressible data streams – the demanding enthusiast user would be well advised to include this drive on a final shortlist. Additionally, Toshiba’s recent acquisition of OCZ is going to cement their development position in the Solid State marketplace … the future is bright for Toshiba.

We have already reviewed the latest OCZ Vertex 460 240GB Solid State drive which features 19nm Toshiba Toggle Mode MLC NAND. Results between the Vertex 460 and Toshiba HG6 are closely matched although OCZ’s Indilinx Barefoot 3 M10 controller delivers marginally better write performance.

The Toshiba HG6 256GB drive scored well in all our tests today, and the results highlight benefits over the ever popular LSI Sandforce 2281 controller when dealing with incompressible data.

Performance in ATTO highlighted peaks over 550 MB/s in sequential read tests, and around 520 MB/s in sequential write tests, slightly better than the manufacturers official claims.

Overall IOPS performance is excellent, achieving close to 89,000 IOPS in our 4K random read test. The 4k random write test wasn’t quite so impressive, hitting a final result around 58,000 IOPS.

As we go to press, the drives are not available to buy, however Toshiba did send over their expected UK retail pricing:

Toshiba HG6 128GB: ~£78
Toshiba HG6 256GB: ~£140
Toshiba HG6 512GB: ~£300

  • 4k IOPS performance.

Kitguru says: A very capable well priced drive, targeting a wide market.
