Toshiba’s BG3 series leverages the Host Memory Buffer (HMB) feature in NVMe Revision 1.2.1 to maintain high performance without integrated DRAM by using host memory for flash management purposes. This powerful combination allows devices to harness the performance of NVMe storage while maximizing footprint and affordability to deliver a next-generation mobile experience to end users. Both fast and economical, these miniaturized SSDs also offer data center and enterprise applications an alternative solution for server boot storage.

By eliminating DRAM from its design, Toshiba’s BG3 series measure 1.3mm in height.

The SSDs have a PCIe  Gen3 x2 lane and NVMe Revision 1.2.1 architecture and deliver to up to 1520 MB/s sequential read, 2.7 times the theoretical maximum bandwidth of SATA 6Gbit/s and up to 840 MB/s sequential write..

Additionally, BG3 also features SLC cache  to accelerate burst type workloads.

The ultra-compact BG3 series is available in 128GB, 256GB, and 512GB capacities[. All three models are available in a surface-mount BGA (M.2 1620) or a removable module (M.2 2230) form factor for platform design flexibility.

BG3 has a Toshiba-developed controller and firmware  integrated with Toshiba Flash memory and is optimised for performance, low power, and reliability. To address modern security needs, self-encrypting drive options (SED) with TCG  Opal Version 2.01 are available.
