Seagate Technology has refreshed three of its enterprise hard disk drives, the Savvio 10K.6 for enterprise-level performance, the Constellation ES.3 for bulk data storage and Constellation CS for replicated bulk storage in the cloud.

The company has split its Constellation 3.5-inch family of hard drives into capacity-optimized devices and cost-optimized hard disk drives. Seagate’s Constellation ES.3 drives, also called the Seagate Enterprise Capacity 3.5 HDD, are high-capacity drives for bulk data center applications. The ES.3 enterprise drives have an increased capacity of 4 TB in a 3.5-inch form factor for tier two storage.

The ES.3 HDDs run at 7200 RPMs and they are optimized for replicated storage in cloud systems, cloud storage servers, cloud storage arrays and cloud backup storage. They are available in 500 GB, 1 TB, 2 TB, 3 TB and 4 TB capacities and targeted for high-workload, multi-drive data centers with SAN, NAS and direct-attached storage arrays. The devices come with 64 MB or 1 28MB cache and feature 6 Gb per second SAS or SATA interfaces, while sustaining 1.4 million hours MTBF compared to the previous 1.2 million.

“The 7200 drives store lots of data that is not immediately available. It’s more of a workhorse of the storage system,” said Barbara Craig, Seagate’s senior product marketing manager.

Seagate’s low-powered, entry-level Constellation CS drives, also called the Seagate Enterprise Value HDD, are designed for high capacity, bulk storage needs specifically for cloud service providers who build replicated environments that handle replicated cloud storage, cloud storage servers, cloud storage arrays, cloud backup storage in DAS and NAS systems. The devices, which have an instant secure erase option, come in 1 TB, 2 TB and 3 TB capacities with 6 Gbps SAS interface. The 7200 RPM drives can handle 0.8 million MTBF.

Seagate’s third new drive is the Savvio 10K, 2.5-inch drive, also called the Seagate Enterprise Performance 10k hard drive. It comes in a smaller form factor and it has a faster performance compared to the previous Savvio 10K.5 version. The new 10.6K drives come in a 2.5 inch form factor and are available in 300 GB, 450 GB, 600 GB and 900 GB capacities. The drives are designed with 6 Gbps SAS or 4 Gbps Fibre Channel interfaces, and the 900 GB capacity drive has a self-encryption Drive (SED) feature. The Savvio 10K.6 also has a sustained data rate of 204 MB per second.

“It has up to 50 percent more capacity and it’s in a smaller form factor,” said Craig. “It is 21 percent faster to the prior generation and it is equal to a 3.5 inch, 15K-RPM sequential performance. We also added a RAID rebuild feature. We do more of a copy function. The good data is copied to reduce the time to rebuild by 80 percent.”
