KIOXIA Launches Industry's First 24G SAS SSDs for Servers, Storage

The next generation of SAS has arrived, bringing improved performance, reliability and data protection along with it. Today, KIOXIA America, Inc. (formerly Toshiba Memory America, Inc.) became the first company to bring 24G SAS to server and storage applications with the introduction of its 6th generation enterprise SAS SSD family. First demonstrated at Flash Memory Summit 2019, KIOXIA's new PM6 Series of enterprise SAS SSDs is built on 24G SAS technology.

Designed for modern IT infrastructures, 24G SAS doubles the data throughput of its predecessor, while implementing new features and enhancements to reach new application performance levels. An established leader in developing SAS SSDs, KIOXIA delivers never-before-seen SAS SSD performance and is the only SSD supplier to offer protection and recovery from two simultaneous die failures in an SSD. The PM6 Series builds upon this history of best-in-class performance and reliability over six generations of SAS drives.

"SAS technology continues to be the interface of choice for many workloads for its reliability and 24x7 operation in the enterprise data center," noted Jeff Janukowicz, research vice president, IDC. "With the launch of the PM6 Series, KIOXIA should be well positioned to deliver on the higher performance and additional features that 24G SAS will provide to server and storage applications."

Featuring KIOXIA's 96-layer BiCS FLASH 3D TLC flash memory, the PM6 Series delivers industry-leading SAS SSD sequential read performance of up to 4,300 megabytes per second (MB/s) / 4,101 mebibytes per second (MiB/s), which is more than a 2x improvement over existing SAS drives. KIOXIA's new drives are available in capacities up to 30.72 terabytes (TB), making them the industry's highest capacity 2.5" SAS SSD.

Key features include:

  • Flexible configuration options: single and wide port, or dual-port for high availability
  • Full range of endurance options for a wide variety of workloads: read-intensive (1 DWPD), mixed-use (3 DWPD) and write-intensive (10 DWPD)
  • Multistream write support to reduce write amplification and extend endurance
  • Full suite of security options available: sanitize instant erase (SIE), TCG Enterprise self-encrypting drive (SED) and FIPS 140-2 certification

As with any new technology generation, a successful shift from 12G to 24G SAS relies on ecosystem enablement and readiness for end-customer deployment. "Broadcom is pleased to work with KIOXIA to bring 24G SAS to the market," said Rick Kutcipal, device ecosystem lead, Data Center Solution Group, Broadcom. "Our early compatibility and interoperability testing is vital to ensure a smooth transition to the next generation of any SSD technology. Successful early testing with the KIOXIA PM6 device, our 9600 series RAID, I/O Tri-Mode controllers, and 24G SAS expanders demonstrates that this solution will provide customers with the full SAS reliability and performance they have come to expect in their server business-critical applications."

"Microchip has worked closely with KIOXIA to complete the industry's first successful 24G SAS end-to-end storage interoperability testing," said Andrew Dieckmann, associate vice president of Microchip's Data Center Solutions business unit. "Testing was conducted using KIOXIA's PM6 Series and Microchip's suite of 24G capable SAS Expanders, SmartROC 3200 and SmartIOC 2200 controller products. The 24G SAS ecosystem is ready to deliver the needed performance, security, and reliability required for next-generation cloud hyperscale and traditional enterprise server storage solutions."

"KIOXIA has one of the broadest SSD portfolios in the industry, and we are proud to lead the transition to SAS-4," noted Alvaro Toledo, vice president of SSD marketing and product planning at KIOXIA America, Inc. "By building our PM6 Series around 24G SAS technology, we're once again raising the bar for enterprise storage performance, reliability and data protection."
