Launches XG5 line-up of client SSDs with capacities up to 1024GB[1] in thin single-sided form factor
May 29, 2017
TOKYO—Toshiba Memory Corporation (hereinafter Toshiba) today launched the XG5 series, a new line of NVM Express™ (NVMe™) SSDs integrating 64-layer, 3D flash memories, with a maximum capacity of 1024GB in a thin single-sided form factor. Sample shipments to OEM customers start today in limited quantities, and Toshiba will gradually increase shipments from the third calendar quarter of this year.
The new SSDs, equipped with Toshiba’s latest 64-layer, 3-bit-per-cell TLC (triple-level cell) BiCS FLASH™, utilize the features of PCI EXPRESS® (PCIe®) Gen3 x 4 lanes and SLC cache to deliver 3000 MB/s sequential read[2] and 2100 MB/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, 256GB, 512GB 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 will be exhibited at COMPUTEX TAIPEI in Taipei, Taiwan, from May 30 to June 3.
Toshiba will continue to strengthen its SSD storage solutions, utilizing cutting-edge flash memory technology to meet diverse market needs.

Notes
[1] Definition of capacity: Toshiba 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.
[2] Toshiba survey based on sequential read and write speeds of 128KiB units, using 1024GB 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 (MB) as 1,000,000 bytes and a kibibyte (KiB) means 210 bytes, or 1,024 bytes.
