  • 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 1 GB = 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, 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.
  • TBW: Terabytes Written. The number of terabytes that may be written to the SSD for the specified lifetime.
  • PCIe is a registered trademark of PCI-SIG.
  • NVMe is a registered or unregistered mark of NVM Express, Inc. in the United States and other countries.
