The XD5 Series is a Data Center NVMe SSD that  utilizes Toshiba Memory Corporation’s 64-layer BiCS FLASH™ 3D memory with a PCIe® Gen3 x4 interface. The XD5 Series is optimized for low latency and performance consistency under read-intensive workloads.

It includes power-loss protection and data path protection to safeguard data, in 2.5 inch form factor,7.0 mm Z - Height.

The XD5 Series offers 1 DWPD (Drive Writes Per Day) and is designed to deliver high performance (up to 2,700MB/s sequential read) with low power consumption (typically less than 7W)

Key Features
  • Up to 3.84TB capacity with a PCIeR Gen3 x4 lane Interface
  • Up to 250K IOPS random read (4KiB) performance
  • Low operating power
  • Optimized for low latency
  • 2.5 inch form factor
  • 1 DWPD under 100% random write workload
  • Power-loss-protection and end-to-end data protection

KEY Applications
  • Cloud-based applications
  • NoSQL databases
  • Big data analytics
  • Streaming media

  • 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 drive write per day means the drive can be written and re-written to full capacity once a day every day for five years, over the stated product warranty period. Actual results may vary due to system configuration, usage and other factors.
  • Read and write performances 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)
  • There are some models of Toshiba Memory Corporation SSD Products which deliver various security functions as optional feature. For more information of security options, please contact your Toshiba Memory Corporation sales representative.
