Originally published at Internet.comSeagate offers multiple drive lines targeted to both consumer and enterprise implementations. Among the drives aimed at enterprise uses (including NAS, SAN, nearline storage, etc., depending on model) are the Cheetah, Savvio, and Barracuda ES families (a separate branch of the Barracuda family, the Barracuda 7200s, is targeted to desktop implementations). All are available separately.
A sampling of high end drive offerings in each of the product families include:
- The new Cheetah 15K.6 drives boast a 15,000 RPM platter speed and are offered with SAS or Fibre Channel interfaces. Offered capacities are 146, 300, and 450 GB; and sustained transfer rates range up to 164 MB/sec.
- The Savvio 10K.2 drives are smaller (2.5 inch) drives targeted primarily to rack/blade server deployments. The 10,000 RPM drives are offered in 73 and 146 GB capacities (3 Gb/sec SAS) and feature an average read/write seek time of 3.8/4.4 milliseconds, and a sustained transfer rate of 55 to 89 MB/sec (inner to outer diameters).
- The Savvio 15K is a 2.5 inch 15K rpm SAS drive. The drive is offered in capacities of 36 & 73 GB and is listed with an average read/write time of 2.9/3.3 milliseconds and sustained transfer rate of 79 to 112 MB/sec (inner to outer diameter).
- The Barracuda ES and ES.2 drives are 7200 RPM drives that boast the vendor's perpendicular recording technology, boosting potential capacity to up to 1 TB. The Barracuda ES drives are offered with SATA interfaces, while the ES.2 offerings ship with either SAS or SATA interfaces. ES drives ship in multiple capacities of from 250 GB to 750 GB, while the ES.2 is offered in capacities of 500 GB, 750 GB, or 1 TB.
ES features include an average read/write seek time of 8.5/9.5 milliseconds, an 8 or 16 MB cache, and sustained transfer rates of 72 or 78 (SATA 750GB) MB/sec. The ES.2 delivers an identical read/write seek time, but increases the cache to 16 or 32 MB and the sustained maximum transfer rate to 105 MB/sec.
The drives are available now, with the exception of the new Cheetah 15K.6 which is expected to begin shipping this month.
