KIOXIA BG7 M.2 Client PCIe Gen4 NVMe SSD
KIOXIA BG7 Series is a line-up of compact form factor NVMe SSDs with capacities up to 2,048 GB, and leverages a PCIe 4.0, NVMe 2.0d specification compliant interface and KIOXIA BiCS FLASH generation 8 TLC flash memory. With higher bandwidth, improved flash management and Host Memory Buffer (HMB) technology, the BG7 Series SSDs deliver very high read performance for compact form factor SSDs of up to 7,000 MB/s (sequential read) and up to 1,000K IOPS (random read).
KIOXIA BG7 Series SSDs are available in capacities of 256 GB, 512 GB, 1,024 GB and 2,048 GB in M.2 Type 2230, Type 2242 and Type 2280 module form factors, making them suitable for thin and light system designs, such as ultra-thin PCs and AI PCs. The BG7 Series offers a Self-Encrypting Drive (SED) model option, supporting TCG Opal Version 2.01.
  Additional Features and Benefits Include:
- Capacities of 256GB, 512GB, 1,024GB and 2,048GB.
- PCIe 64 gigatransfers per second (GT/s) interface (Gen4 x4 lanes).
- Up to 7,000 megabytes per second (MB/s) sequential read and 6,000 MB/s sequential write.
- Up to 1,000,000K IOPS random read and 1.000,000K IOPS random write.
- Forward looking support for the NVMe 2.0d feature set and basic management command over System Management Bus (SMBus), enabling tighter thermal management.
- Support for the latest TCG Pyrite and Opal standards, as well as end-to-end data protection ensures data is secure whether at home or in the office.
- Power Loss Notification signal support to protect data against forced shut downs.
- Sideband signal (PERST#, CLKREQ# and PLN#) support for both 1.8V and 3.3V.
- Support platform firmeware recovery feature.
