Kioxia Announces Delivery of PCIe 4.0 Solid State Drives

February 21, 2020

TOKYO, Feb. 21, 2020 — PCI Express 4.0 was designed to enable doubling the performance of client, server and storage systems, pushing speeds up to 16.0GT/s (gigatransfers per second throughput per lane), driving new performance levels for cloud and enterprise applications. Today, Kioxia Corporation, the world leader in memory solutions, has announced that its lineup of PCIe 4.0 NVMe enterprise and data center solid state drives (SSDs) are now shipping to customers[1].

Kioxia Corporation: PCIe 4.0 NVMe Enterprise and Data Center SSDs

An established leader in developing PCIe 4.0 NVMe SSDs, Kioxia continues to push the limits of flash storage performance. Kioxia was the first company to publicly demonstrate PCIe 4.0 SSDs[2], and is now the first to commence shipment of these next-generation drives.

CM6 Series Enterprise NVMe SSDs
Dual-ported for high-availability, Kioxia’s CM6 Series of PCIe 4.0, Gen4 4lane (or Dual-port, 2lane), and NVMe 1.4 Enterprise SSDs deliver best-in-class[3] sequential and random read/write performance of up to 6.9 GB/s and up to 1.4M IOPS. These represent improvements of up to 2x over its PCIe 3.0 predecessors and are 12x faster than typical SATA drives[4]. Designed for enterprise applications and use cases – including high-performance computing, artificial intelligence, caching layer, financial trading and data analytics – the CM6 Series are available in capacities of up to 30.72TB[5].

CD6 Series Data Center NVMe SSDs
Kioxia’s CD6 Series of PCIe 4.0, Gen4 4lane and NVMe 1.4 data center SSDs are single-ported for servers, and targeted to hyperscale data center and general purpose applications, such as database, cloud/container environments, web servers and media streaming. The CD6 Series will be available in capacities of up to 15.36TB, with up to 6.2GB/s throughput and 1.0 M IOPS random access performance.

Both the CM6 and CD6 Series have a lineup of 1 DWPD (Drive Write per Day) and 3 DWPD[6], and include a broad range of security/encryption options[7]. Also, the new SSDs have successfully passed PCI-SIG Workshop compliance and are on the UNH-IOL Integrator’s list for NVMe 1.4 device compatibility.

[1] Samples of 30.72TB products are scheduled to be available after June.

[4] Compared to existing SATA interface Kioxia products. Kioxia Corporation survey.
Performance estimates are preliminary and subject to change without notice.
[5] 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, 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, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
[6] 1DWPD models will be available in capacities of 960GB to 30.72TB, while the 3DWPD models will be available in capacities of 800GB to 12.8TB.
[7] Availability of security/encryption options may vary by region.
