New SSDs are optimized for mixed workloads, such as online transaction processing, database or Web indexing, and email.
Seagate started shipping its new Pulsar solid-state drives -- 2.5-inch SSDs the company claims are the fastest it has ever manufactured -- July 18 to its channel partners.
Seagate said that the 400GB Pulsar XT.2 uses SLC (single-level cell) flash with a native 6Gb/s SAS (serial-attached SCSI) interface. The XT.2 is optimized for mixed workloads typical of enterprise environments, such as OLTP (online transaction processing), database or Web indexing, and email.
A more capacious version, the 800GB Pulsar.2, is scheduled to become available July 29. Seagate claimed that this is the first MLC (multi-level cell) flash-enabled SSD made available by an enterprise hard-drive producer.
In a single storage device configuration, the XT.2 produced an SPC-1C result of 20,008.82 SPC-1 IOPS with an average response time of 2.05 milliseconds over a 10-minute duration, compared with an SPC-1C Sustainability Test result of 20,011.07 IOPS with an average response time of 2.08 milliseconds over four hours.
SPC (Storage Performance Council, an independent storage research firm) benchmark results on testing of the Pulsar can be found here.
The Pulsar.2 is aimed specifically for data centers, unlike typical MLC solid-state drives built for consumer applications. The Pulsar.2 holds up to 800GB and has built-in intelligence, in that it is able to automatically detect and correct data errors that could plague normal drive operations, Seagate said.
