The CD5 Series is a read-intensive data center NVMe SSD that is optimized to support a broad range of scale-out and cloud applications that include Big Data/IoT, Online Transaction Processing, and Virtualization. CD5 SSDs, with a PCIe® Gen3 x4 lane interface, deliver consistent performance up to 550K IOPS (random read) and 50K IOPS (random write), with active power consumption of 11-13W.

Featuring Toshiba Memory Corporation’s 64-layer BiCS FLASH 3D TLC memory, CD5 SSDs deliver <1 DWPD (Drive Writes Per Day) of endurance and storage capacities up to 7.68TB in a 2.5 inch form factor, making them suited for hyperscale data center applications.

  • Definition of capacity: Toshiba Memory 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.
  • GT/s:Giga Transfers per second
  • A kibibyte (KiB) means 210, 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 Write 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 five years, the stated product warranty period. Actual results may vary due to system configuration, usage and other factors.
  • Read and write speed, based on the sustained state of SSD, may vary depending on the host device, read and write conditions, and file size.
  • IOPS: Input Output Per Second (or the number of I/O operations per second)
