Toshiba Announces Third Generation of Enterprise SAS SSDs

Delivering the highest random read performance of 270,000 IOPS with 12Gbit/s SAS interface

IRVINE, Calif. — (BUSINESS WIRE) — August 3, 2015 — The Storage Products Business Unit of Toshiba America Electronic Components, Inc., a committed technology leader, today announced its next generation of enterprise solid state drives (eSSDs) for the PX Series. The new PX04S line features four serial-attached small computer system interface (SCSI) SAS eSSD models well-suited for enterprise applications including: mail servers; database servers; virtualized enterprise file servers; and primary storage in read, write or mixed workload environments. Continuing Toshiba’s legacy of quality and reliability, the dual-ported 12Gbit/s1 SAS PX04S Series offers impressive random 4K performance with read IOPS up to 270K and write IOPS up to 125K. This is Toshiba’s first 12Gbit/s SAS SSD to deliver 3.84TB2 of operating capacity.

The PX04S line features four eSSD models – PX04SHB, PX04SMB, PX04SVB and PX04SRB – each offering a range of capacities and optimized for different applications and workloads:

High-Endurance: Targeted at applications requiring the highest levels of eSSD performance, reliability and endurance, the PX04SHB supports 25 complete drive writes per day (DWPD3) with a one hundred percent random workload and is available in a range of capacities from 200GB to 1.6TB. Write-intensive virtualized data centers, big data analytics and high performance computing (HPC) workloads will benefit from the impressive performance and data integrity afforded by the PX04SHB.

Mid-Endurance: For mixed-use, mission-critical hyperscale and virtualized environments, Toshiba’s PX04SMB provides very high levels of predictable performance to optimize system and application performance. The PX04SMB offers 10 DWPD with capacities up to 3.2TB and is suitable for online transaction processing (OLTP) and e-commerce.

Value-Endurance: The PX04SVB is optimized for read-intensive server and storage applications, requiring a balance of reliability, capacity and endurance. Capable of three DWPD with capacities up to 3.84TB, PX04SVB SSDs are suited for read-intensive applications such as media streaming, data warehousing and web servers.

Read-Intensive: Targeted at read-intensive applications requiring one DWPD or less, the PX04SRB delivers features and performance suited for a range of enterprise and web-based workloads like video on demand (VOD) and data warehousing. The PX04SRB is available in capacities up to 3.84TB.

The PX04S Series is available in the 2.5-inch/15mm form factor for alignment with enterprise server and storage arrays. In addition to power-loss protection and full data path protection, each model is available as a self-encrypting drive (SED TCG compliance) with instant secure erase and supports pin-3 power disable for improved enclosure services control over storage media. The PX04S Series features customer-tunable power and performance allowing optimization for power efficiency or maximum performance. The PX04S Series SAS SSDs are backed by Toshiba’s limited five-year warranty4.

Toshiba’s integrated SSD design and manufacturing capability ensure that key components of the SSD, including NAND flash, are designed by Toshiba, leveraging Toshiba’s vertical integration and leadership strengths in the growing SSD market. Component and design commonality also potentially reduces qualification time for Toshiba customers and reflects Toshiba’s collaborative approach to SSD design and manufacturing.

“This is our third generation of SAS SSDs and our second with 12Gbit/s. The new PX04S Series leverages years of Toshiba innovation and vertical integration. The result is an SSD architecture designed and optimized for the next-generation of virtualized enterprise and hyperscale data centers,” said Cameron Brett, director of SSD product marketing at Toshiba Storage Products Business Unit.

"Enterprise customers need storage solutions that are optimized for different applications and workloads,” said Jeff Janukowicz, Research Director for Solid State Drives and Enabling Technologies at IDC. "SAS SSDs, such as Toshiba’s PX04S Series, that provide the ability to manage power and performance allow customers to better manage their storage environment and deliver the flexibility to meet ever changing service-level agreements."

“Supermicro offers a broad range of SAS3 12Gbit/s optimized server and storage platforms and combined with Toshiba’s new 2.5-inch PX04S Series eSSDs, our customers benefit from the latest innovations in high performance storage,” said Don Clegg, Vice President of Marketing and Business Development, Supermicro. “Our latest 4U 90x top-load, hot-swap JBOD solution ( SC946ED-R2KJBOD), when fully populated with Toshiba PX04S Series eSSDs, provides customers with high-performance, high-availability storage available for the most data-intensive, mission critical applications and workloads.“

Samples of the PX04S Series are available now and will be on display next week at Flash Memory Summit in San Jose, Calif. in Toshiba’s booth #407.
