Seagate offers three families of solid-state and hard disk drives with compact form factors and power-saving features.

Technology launched two new members of the Pulsar solid-state drive family, two
next-generation Savvio 15K and 10K hard disk drives, and the latest
Constellation ES.2 3TB HDD. The Pulsar.2 and Pulsar XT.2 automatically detect
and correct a multitude of data errors that can occur during normal drive
operations, while the Savvio and Constellation HDD offerings feature compact
The Pulsar XT.2 is a 2.5-inch, SLC-based, native 6G-bps SAS enterprise SSD with capacities of as much as 400GB. It is the fastest drive in the Seagate portfolio, with sustainable random reads at 48K and writes at 22K IOPS and sequential reads at 360MB/sec and writes at 300MB/sec. The Savvio 10K.5 is a 2.5-inch small-form-factor enterprise-class HDD with up to 900GB of storage, while the Savvio 15K.3 offers capacities of 300GB and 146GB.
"The surge in storage consumption is being driven not only by the growth of content and use within the enterprise, but also by new applications and devices that directly or indirectly consume enterprise storage," said Kurt Richarz, Seagate executive vice president of product line management. "Seagate's new family of enterprise storage solutions meets the diverse storage needs of these high-growth application environments, whether it's fast transactional database servers, bulk storage and archiving, or everything in between."
With 3TB capacities, the Constellation ES.2 HDD powers both server and bulk storage solutions, maximizing the storage footprint by supporting up to 114TB per square foot. The Constellation ES.2 also introduces a new Seagate RAID Rebuild feature for enterprise HDDs, which reduces the hours of lost productivity during RAID recoveries. And it features the SAS-based Protection Information feature for end-to-end data protection, Self-Encrypted Drive (SED) option for protecting data-at-rest, Rotational Vibration Feed Forward (RVFF) technology that sustains performance when placed in closely packed multidrive system environments, and PowerChoice on-demand low-power options.
"When we increase the possibility for storage at any point in the World Wide Web, we increase the possibility for storage at every point in the World Wide Web," said John Monroe, a research vice president in Gartner's Data Center Systems group. "Media tablets and other smart handheld devices will serve to generate an even greater need for enormous amounts of both high-capacity and high-speed storage in the cloud, which will in turn require diverse new breeds of storage building blocks to manage this explosive and complex data growth in more efficient, reliable and cost-effective ways."
