XD6 Series

Data Center SSD

The XD6 series is in the position of successor of the XD5 series and is under development for shipment after 2020 calendar year.  XD6 series supports PCIe® Gen4/Gen3 x4 interface, and a capacity line up is up to 3.84 TB with M.2 22110 form factor that utilizes KIOXIA Corporation’s BiCS FLASH™ 3D memory.
The XD6 Series offers 1 DWPD (Drive Writes Per Day) and plans to enhance performance up to 3,200 MB/s sequential read, 500 KIOPs random read, respectively. Optional self-encrypting drive (SED) models supporting TCG Opal will also be offered.

  • 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 = 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.
  • A kibibyte (KiB) means 210, or 1,024 bytes.
  • 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)
