Toshiba Corp. has introduced its new family of consumer-class solid-state drives that offer high performance, power efficiency, and is suitable for a wide range of applications from ultra-thin notebooks to data center servers. The drives are claimed to be the first SSDs to use Toshiba 19nm MLC NAND flash memory with toggle 2.0 interface.


Toshiba HG6 family of solid state drives relies on Toshiba’s own controller and firmware and are based on Toshiba’s most advanced NAND flash memory produced using 19nm process technology that boasts low manufacturing cost amid high performance and reliability. The SSDs utilize Serial ATA-6Gb/s interface, are available in various form-factors (including 2.5” (7mm/9.5mm heights), mSATA and M.2 (single-sided, dual-sided)), and in capacities up to 512GB. Performance of the HG6 series SSDs is similar to other mainstream SATA-6Gb/s drives: up to 534MB/s sequential read speed as well as up to 482MB/s sequential write speed (see full specs below).

Engineered with enterprise class technology for data integrity, the HG6 series incorporates Toshiba’s proprietary QSBC (Quadruple Swing-By Code) error-correction technology, a highly efficient error correction code (ECC), which helps protect customer data from corruption caused by NAND wear, thus improving the reliability of and extending the usable life of the SSD. The series also includes end-to-end data path protection and a self-encrypting feature option that is compliant with Trusted Computing Group (TCG) Opal 2.0, the TCG specification for self-encrypting drive function.

“With the HG6 series, customers can trust they are using a storage solution with high performance and power efficiency that is ideal for a wide range of applications. As inventors of NAND technology, we leverage our NAND expertise to optimize the performance and data integrity of this series, and truly give customers the power of choice with a broad selection of capacities and form factors,” said Don Jeanette, senior director of marketing at Toshiba storage products business unit.

The first commercial HG6 SSDs will ship next month.
