Computex: Toshiba XG5 Line-up NVMe SSDs Using 64-Layer 3D Flash Memory …

Toshiba Memory Corporation launched the XG5 series, a line of NVM Express (NVMe) SSDs integrating 64-layer, 3D flash memories, with a maximum capacity of 1,024GB ^[1] in a thin single-sided form factor.

Sample shipments to OEM customers start in limited quantities, and the company will gradually increase shipments from 3Q17.

These SSDs, equipped with firm’s latest 64-layer, 3-bit-per-cell TLC BiCS Flash, utilize the features of PCIe Gen3 x 4 lanes and SLC cache to deliver 3,000MB/s sequential read ^[2] and 2,100MB/s sequential write ^[2]. They are also more efficient than Toshiba existing products ^[3] and reduce standby mode power consumption by over 50%, to less than 3mW ^[4].

The SSDs will be available in three capacities, 256, 512 and 1024GB, in M.2 2280 ^[5] single-sided form factors. Self-encrypting drive (SED) models ^[6] supporting TCG Opal Version 2.01 will also be offered, making the XG5 series highly suited to a wide range of applications including ultra-mobile PCs that prioritize performance and business applications requiring security.

The XG5 series SSDs was exhibited at Computex in Taipei, Taiwan, from May 30 to June 3.

^[1] Definition of capacity: Toshiba defines a gigabyte (as 1,000,000,000 bytes. A computer OS, however, reports storage capacity using powers of two 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 OS, such as Microsoft OS and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
^[2] Toshiba survey based on sequential read and write speeds of 128KB units, using 1,024GB models in the XG5 series under Toshiba test conditions. Read and write speed may vary, depending on the host device, read and write conditions, and file size. Toshiba defines a megabyte as 1,000,000 bytes and a kilobyte means 210 bytes, or 1,024 bytes.
