Toshiba HG6 256GB SSD review
1. Features, specs
We have in our labs one of the Toshiba's latest HG series of Solid State Drives (SSDs). The HG6 mainstream drives take advantage of Toshiba’s Advanced 19nm (A19nm) toggle 2.0 MLC (multi level cell) NAND, which delivers advances in performance and power efficiency.
The HG6 series SSDs are available in capacities ranging from 60GB to 512GB and boast maximum sequential read speeds of 534MB/s and maximum sequential write speeds of 482MB/s. It is based on an SSD controller made by Toshiba. The controller supports ‘adaptive SLC emulation’, which allows for improved writing performance.
The drives are available in a variety of form factors, including space saving mSATA, M.2 and in standard 2.5inch (64mm) widths with heights of 7mm and 9.5mm.
The drives are fitted with a 6Gbit/s SATA 3.1 interface and include Adaptive Size SLC Write cache technology and optional Self Encrypting feature compliant to TCG-Opal 2.0. All HG6 SSDs incorporate Toshiba’s Quadruple Swing-By Code (QSBC) for improved error correction and reliability. Toshiba says that the drives have a reliability rating (MTTF) of up to 1,500,000 hours.
