Toshiba Announces Third Generation of Enterprise SAS SSDs

Toshiba has announced its next generation of enterprise solid state drives designed for applications ranging from email servers, database servers, and virtualized enterprise file servers, to primary storage in read, write or mixed workload environments. The new line is called the PX04S and features high-endurance, mid-endurance, value endurance and read-intensive models optimized for different applications and workloads.

The PX04S line is equipped with dual-port 12Gbps SAS interfaces and it can achieve a sustained random 4K read performance up to 270K, the highest for a 2.5-inch form factor SAS SSD. The write performance has also been improved and the drive can now deliver 125K in that area. This is also Toshiba’s first 12Gbps SAS SSD series able to deliver 3.84TB of operating capacity.

The high-endurance PX04SHB models are targeted at write-intensive virtualized data centers, big data analytics, and high-performance computing that requires the highest levels of eSSD performance, reliability and endurance. The PX04SHB supports 25 complete drive writes per day (DWPD) with a one hundred percent random workload and is available in capacities from 200GB to 1.6TB.

The PX04SMB are the mid-endurance drives that have been optimized for mixed-use in mission-critical hyper-scale and virtualized environments. The drives provide very high levels of predictable performance for optimal system and application performance and support 10 DWPD with capacities of up to 3.2TB.

The PX04SVB value-endurance models are optimized for read-intensive server and storage applications that require a balance of reliability, capacity, and endurance. Capable of three DWPD and with capacities up to 3.84TB, the PX04SVB SSDs are suited for applications such as media streaming and web servers.

Finally, targeted at read-intensive applications requiring one DWPD or less, the PX04SRB delivers features and performance suitable for a range of enterprise and web-based workloads such as video on demand (VOD) and data warehousing. The PX04SRB models are available in capacities up to 3.84TB.

The new drives will, of course, be presented at next week’s Flash Memory Summit in San Jose, California.
