Toshiba Memory Corporation Unveils SATA Client SSD Utilizing 64-Layer, 3D Flash Memory

  • August 08, 2017

TOKYO - Toshiba Memory Corporation, the world leader in memory solutions, today announced the launch of the SG6 series, a new line-up of SATA client SSDs utilizing Toshiba Memory Corporation's cutting-edge 64-layer, 3-bit-per-cell (TLC) BiCS FLASH™. Sample shipments to PC OEM customers start today in limited quantities, and Toshiba Memory Corporation will gradually increase shipments from the fourth calendar quarter of this year.

Client SSD “SG6 Series”

The new SG6 series SSDs features a SATA Revision 3.3, 6.0Gbit/s interface, and delivers performance of up to 550MB/s sequential read and 535MB/s sequential write[1]. Thanks to improved flash memory management and performance, active power consumption is cut by approximately 40% compared to previous generation products[2]. This improvement can extend battery life, a plus for many applications including mobile computing.

The new series will be available in three capacities, 256GB, 512GB and 1024GB[3]. Each capacity is aligned with two form factors: 2.5-type for hard disk drive (HDD) upgrades; and M.2 2280[4] type for mainstream mobile PCs. Security needs will be addressed by offering self-encrypting drive (SED) models supporting TCG Opal Version 2.01[5]

The SG6 SSD series also supports Toshiba’s proprietary QSBC™ (Quadruple Swing-By Code) error-correction technology, an efficient error correction code (ECC) that helps to protect customer data from corruption and improves reliability, realizing efficient and accurate data processing.

The SG6 series will be exhibited at the Flash Memory Summit 2017 in Santa Clara, California, USA from August 8 to 10, at Booth #407.

Notes:
[1] Toshiba Memory Corporation survey based on sequential read and write speeds of 128KiB units, using 1024GB models in the SG6 series under Toshiba Memory Corporation test conditions. Read and write speed may vary, depending on the host device, read and write conditions, and file size. Toshiba Memory Corporation defines a megabyte (MB) as 1,000,000 bytes and a kibibyte (KiB) as 210 bytes, or 1,024 bytes.
[2] SG5 series
[3] Definition of capacity: Toshiba Memory Corporation defines a gigabyte (GB) as 1,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 bytes = 1,073,741,824 bytes, and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
[4] The form factor of the 256GB and 512GB models is M.2 2280-S2 and for the 1024GB model it is M.2 2280-D2.
[5] Availability of the SED model line-up may vary by region.
