Toshiba is expanding its line-up of client SSDs with the launch of premium models in its XG5-P series - new NVM Express (NVMe) client SSDs improve on the performance of the current models and double the maximum capacity to 2TB.

Toshiba has started sampling the new XG5-P models in limited quantities and 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 (sequential read and write speeds of 128KiB units on the state of "SLC cache=ON"), and up to 320,000 IOPS random read and 265,000 IOPS random write (random read and write speeds of 4KiB units, "SLC cache=ON"). Its random read/write performance in full access range is approximately 55% better than that of standard XG5 series products. At the same time, low power consumption is maintained at less than 60mW during operation.

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.

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