» Toshiba Memory Corporation Unveils 2TB NVMe SSD TechNews


Toshiba Memory Corporation, the world leader in memory solutions, has enhanced its line-up of client SSDs with the launch of premium models in its XG5-P series. The new NVM Express (NVMe) client SSDs improve on the performance of the current XG5 series models and double the maximum capacity to 2TB[1]. Sample shipments to OEM customers start today in limited quantities, and Toshiba Memory Corporation will gradually increase shipments from the first calendar quarter of 2018.

The XG5-P series also utilizes a PCI Express(PCIe) Gen3 x 4 lane and NVM Express Revision 1.2.1 interface, and delivers performance of up to 3000 MB/s sequential read and 2200 MB/s sequential write[2], and up to 320,000 IOPS random read and 265,000 IOPS random write[3]. Its random read/write performance in full access range[4] is approximately 55% better than that of standard XG5 series[5] products. At the same time, low power consumption is maintained at less than 60mW during operation[6].

The new XG5-P series is housed in a standard M.2 2280 form factor and will be available in two capacities, 1TB and 2TB. By utilizing a 64-layer, 3D flash memory BiCS FLASH™ 1TB package developed in-house, the 2TB model offers twice the maximum storage capacity of the standard XG5 series on the same 2.23mm, lightweight single-sided M.2 2280 module. By maintaining a single form factor for all capacities across the XG5-P and XG5 product families, Toshiba Memory Corporation makes it easier to design platforms that need flexible storage.

The XG5-P SSDs will also be available in self-encrypting drive (SED) models[7] supporting TCG Opal Version 2.01, contributing to a wide range of applications including workstations, gaming PCs and read-intensive enterprise use.

Notes
[1] Definition of capacity: Toshiba Memory Corporation defines a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1TB=240bytes = 1,099,511,627,776 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 Memory Corporation survey based on sequential read and write speeds of 128KiB units on the state of “SLC cache=ON” 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 210bytes, or 1,024bytes.
