Seagate introduces 2.5-inch Pulsar XT.2 and Pulsar.2 SSDs

These enterprise-class hard drives will supposedly deliver the consistent performance and outstanding data integrity needed for the most demanding applications

The popular hard disk drive manufacturer Seagate has announced its latest solid state drives specifically for enterprise and data center use called the Pulsar XT.2 and Pulsar.2.

The 2.5-inch XT.2 drive natively supports SAS at 6Gb/sec and is “optimized for complex, mixed workloads typical of enterprise environments such as online transaction processing (OLTP), database or web indexing, and email.” Seagate is also promising “outstanding and consistent enterprise-class performance over time” as the XT.2 has been rigorously tested for I/O stability, data integrity and reliability under the stringent SPC-1C benchmark. With sustained and I/O data transfers rates at 360MB/sec and 600MB/sec, respectively, the XT.2 is certainly no slouch, either.

Meanwhile, Seagate is touting the Pulsar.2 as the first Multi-Level Cell (MLC) Flash-enabled SSD from an enterprise hard drive maker. This particular model has the ability to automatically detect and correct data errors that could otherwise damage or endanger the drive. The Pulsar.2 drive is compatible with both SAS and SATA interfaces at up to 6Gb/sec.

Most SSD suppliers aren’t fully aware of the needs of the enterprise,” said Jim Handy of Objective Analysis in the press release. “Without data integrity and reliability, an SSD is worthless to most enterprise users.

The hotpluggable Pulsar XT.2 is currently listed at 100GB, 200GB and 400GB capacities, while the Pulsar.2 is available only at the 800GB size as of this writing. Shipment of the Pulsar.2 SSD is expected to begin July 29th, although pricing for all models is still unknown. General availability of both models is expected sometime later this year.
