Series
Client SSD
The KIOXIA BG5 Series is a line-up of compact form factor NVMe™ SSDs with capacities up
to 1,024 GB, and leverages a PCIe® 4.0, NVMe™ 1.4 specication compliant interface and
KIOXIA 112-layer BiCS FLASH™ 3D TLC (3-bit-per-cell) ash memory. With higher bandwidth,
improved ash management and Host Memory Buer (HMB) technology, BG5 Series SSDs
deliver best-in-class read performance for compact form factor SSDs of up to 3,500 MB/s
(sequential read) and up to 500K IOPS (random read), with active power consumption of up
to 4.3 W (Typ.)*

Specications (Continued)
• Denition of capacity: KIOXIA Corporation denes 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 denition of 1GB = 2^30 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including
examples of various media les) will vary based on le 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.
• Denition of performance: 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 Buer (HMB) = On”, may vary depending on the host D3:D27device, read and write conditions, and le size.
• Read and write performances may vary depending on the host device, read and write conditions, and le size.
• 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 reect actual
operation. Actual operating life of the product may be dierent from the MTTF.
