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.

Toshiba will start sampling the new SSDs in "limited quantities" to its OEM customers, and plans to 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 and 2100 MB/s sequential write. They are also more efficient than Toshiba existing products and reduce standby mode power consumption by over 50%, to less than 3mW.

The SSDs will be available in three capacities, 256GB, 512GB and 1024GB, in M.2 2280 single-sided form factors. Self-encrypting drive (SED) models supporting TCG Opal Version 2.01 will also be offered.
