- 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.
- GT/s: Giga Transfers per second.
- A kibibyte (KiB) means 2^10, or 1,024 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.
- DWPD: Drive Writes Per Day. One full drive write per day means the drive can be written and re-written to full capacity once a day every day for the specified lifetime. Actual results may vary due to system configuration, usage and other factors.
- Read and write speed may vary depending on various factors such as host devices, software (drivers, OS etc.), and read/write conditions.
- IOPS: Input Output Per Second (or the number of I/O operations per second).
- [1] Sanitize Instant Erase (SIE) security optional model is available.
- [2] SIE optional model supports Crypto Erase, which is a standardized feature defined by the technical committees (SCSI) of INCITS (the InterNational Committee for Information Technology Standards).
- [3] Security optional model is not available in all countries due to export and local regulations.
- 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.
