Toshiba Unveils the XG 5 M.2 Performance NVMe SSD

btarunr · May 29, 2017

Toshiba today unveiled the XG 5 series performance-segment SSDs in the M.2-2280 form-factor. These drives take advantage of the PCI-Express 3.0 x4 interface, and the NVMe 1.2 protocol. At the heart of these drives is Toshiba's 64-layer BiCS Flash (3D TLC NAND flash) memory. Available in capacities of 256 GB, 512 GB, and 1 TB, the drive offers sequential transfer speeds of up to 3,000 MB/s reads, with up to 2,100 MB/s writes. The drive features an SLC-cache feature, in which the drive treats a small portion of the TLC NAND flash as SLC NAND, by storing just 1 bit per cell, hot data is juggled in and out of this portion. The drives will go on sale in the first week of June.

Loved the XG3 and it's nice to see Toshiba continue to provide options for fast SSDs.

Any benchmark worth it's salt will detect this. Caching on the other hand is a legit way to deal with standard workloads.

It works good on larger drives, on 256gb models its too small, a few 250gb 960 evo reviews show this, and it drops to really low speeds, while others show it fast as hell throughout

either way i would still rather avoid tlc until the native speed of the stuff comes up a bit
