CD7-R Series
NVMe™ SSD 2.5-inch (U.2)

Data Center SSD


Data Center NVMe™ Read-Intensive SSD

 

The CD7-R 2.5-inch form factor Series is a read-intensive data center NVMe™ SSD that is optimized to support a broad range of scale-out and cloud applications, including big data/IoT, online transaction processing, and virtualization. Built with a PCIe® 4.0 (16 GT/s x4) interface, CD7-R 2.5-inch form factor Series SSDs deliver consistent performance up to 1,100K IOPS (random read) and 180K IOPS (random write), with active power consumption of 11-19 W.
Featuring KIOXIA 96-layer BiCS FLASH™ 3D TLC memory, CD7-R 2.5-inch form factor SSDs deliver 1 DWPD (Drive Writes Per Day) of endurance and storage capacities up to 15.36 TB in a 2.5-inch form factor, making them well-suited for hyperscale data center 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 = 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.
  • 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] The Sanitize Instant Erase (SIE) optional model is available.
  • [2] SIE option supports Crypto Erase, which is a standardized feature defined by NVM Express Inc.
  • [3] Optional security feature compliant drives are 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.
