XG5 Series

Client SSD

XG5 series SSDs feature KIOXIA’s latest 64-layer, 3D TLC (3-bit-per-cell) flash memory BiCS FLASH™. This new line of NVMe™ based client SSDs deliver high performance up to 3000 MB/s of sequential read and 2100 MB/s of sequential write with a maximum interface bandwidth of 32 GT/s. XG5 series SSDs also feature an SLC cache to accelerate burst type workloads, as well as improved power consumption comparing to prior generation XG3, making these SSDs an efficient option for high performance mobile computing.

XG5 Series SSDs are available in 256GB, 512GB and 1024GB capacities in compact single-sided M.2 2280 form factors.

Self-encrypting drive (SED) models supporting TCG Opal Version 2.01 are also offered, making the new series highly suited to address data security needs for commercial PCs or other business applications.

  • 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 = 230 = 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.
  • A kibibyte (KiB) means 210, or 1,024 bytes, a mebibyte (MiB) means 220, or 1,048,576 bytes, and a gibibyte (GiB) means 230, or 1,073,741,824 bytes.
  • 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.
  • Read and write speed may vary depending on the host device, read and write conditions, and file size.
