KIOXIA Announces Next-Generation EDSFF E1.S SSDs for Hyperscale Data Centers

New XD7P Series Data Center NVMe SSDs Deliver Enhanced Performance with PCIe 5.0 Augmentation in Process

SAN JOSE, Calif., October 18, 2022 – Furthering its mission to address future enterprise infrastructure requirements, KIOXIA America, Inc. today announced that it has expanded its broad portfolio of client, enterprise and data center SSDs with the addition of the XD7P Series. Designed for hyperscale and general server applications in the new Enterprise and Data Center Standard Form Factor (EDSFF) E1.S form factor, XD7P drives are the second generation of E1.S SSDs with Open Compute Project® (OCP®) Data Center NVMe® SSD 2.0 specification support from KIOXIA, following its XD6 series. KIOXIA XD7P drives are now sampling to select data center customers1.

“Hyperscale needs of density, power, performance and serviceability are driving PCIe® 5.0, E1.S, as a form factor, and the OCP Data Center NVMe SSD specification V2.0 for the data center,” said Ross Stenfort, hardware storage engineer, Meta.  “The KIOXIA XD7P Series SSD supports these storage technologies to enable the next generation of hyperscale needs.”

XD7P Series Data Center NVMe SSDs deliver overall improved performance, achieving nearly 1.5X to 2X the sequential write performance and random read/write performance, when compared to its predecessor2. XD7P drives are designed to the PCIe 4.0 and NVMe 2.0 specifications, and PCIe 5.0 with maximum interface speed of 32 GT/s (gigatransfers/second) per lane is under development. Hence, XD7P will be released initially as PCIe 4.0 SSDs. PCIe 5.0 SSDs will be released based on customer demand.  

KIOXIA XD7P Series highlights include:

  • EDSFF E1.S form factor with 9.5mm, 15mm and 25mm heat sink options
  • Designed to NVMe 2.0 and PCIe 4.0 specifications (PCIe 5.0 under development)
  • Supports the OCP Data Center NVMe SSD 2.0 r21 specification
  • Built on 5th generation BiCS FLASH™ 3D TLC flash memory and an improved proprietary controller
  • 1 DWPD endurance and supports up to 7.68 terabyte capacity
  • Non-SED and TCG Opal SSC SED options


“As hyperscale data centers get more sophisticated, the E1.S form factor is gaining in popularity over legacy form factors due to its break-through thermal and performance benefits,” said Maulik Sompura, senior director of product planning and management, KIOXIA America, Inc. “KIOXIA is pushing the envelope further with our next-gen XD7P E1.S NVMe and PCIe SSDs, which are equipped to support newly added, complex OCP features. With the XD7P, KIOXIA has made significant strides in capabilities compared to previous generation drives – which can lead to a substantial TCO advantage for customers.”

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 bytes = 1,073,741,824 bytes and 1TB = 2^40 bytes = 1,099,511,627,776 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.

DWPD: Drive Write(s) 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 may vary depending on the host device, read and write conditions, and file size.
