Client SSD
NVMe™ SSD M.2

The BG4 series is a line-up of compact single package NVMe™ SSDs with capacities up to 1,024GB, and leverages a PCIe® Gen3 x4 interface and KIOXIA's 96-layer TLC BiCS FLASH™. With higher bandwidth and improved flash management and Host Memory Buffer (HMB) technology, BG4 SSDs deliver best-in-class read performance in single package SSDs, of up to 2,300MB/s (sequential read) and up to 390K IOPS (random read), with active power consumption of up to 3.7W (Typ.).

The BG4 series is available in four capacities of 128GB, 256GB, 512GB and 1,024GB in surface-mount M.2 1620 single package or removable M.2 2230 module form factor options, making them suitable for thin and light system designs for ultra-thin PCs, as well as embedded devices and server boot in data centers.
The BG4 series is with the option of a Self-Encrypting Drive (SED) model supporting TCG Opal Version 2.01.

  • Product image may represent a design model.
  • Availability of the SED model line-up may vary by region.
  • Definition of capacity: KIOXIA Corporation defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 2^30 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
  • 1 MB (megabyte) = 1,000,000 bytes.
  • IOPS: Input Output Per Second (or the number of I/O operations per second).
  • Read and write speed, tested on the state of "Host Memory Buffer (HMB) = On", may vary depending on the host device, read and write conditions, and file size.
  • Read and write speed may vary depending on various factors such as host devices, software (drivers, OS etc.), and read/write conditions.
  • MTTF (Mean Time to Failure) is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation. Actual operating life of the product may be different from the MTTF.
