Seagate, second largest manufacturer of hard drives
The latest constellation ES.3 includes the sixth generation of Seagate's 7200rpm, 3.5-in enterprise-class HDD that adds another terabyte of capacity at the high end of 4 TB versus 3TB in the predecessor model. This constellation ES.3 uses almost 9 % less power during idle times than the ES.2.
The constellation CS is what which call its enterprise value HDD which is a brand new 7200 rpm. A 3.5- in form factor drives that provide from 1 TB to 3TB of storage. Several low power device operates at under 6.4 watts. The new Constellation CS provides upto 14% faster data tranfer rated than other Seagate's 3.5-in 6Gpbs SATA drive. Sustaining data transfer that ranges from 150 Mb per second to 180 MB per second and compared with the Barracuda's 155 MB per second rate.
The latest new model provides a MTBF of 800,000 hrs versus 600,000 hrs in the Barracuda which has enterprise-class error connection firmware. This drive comes up with a 3-year warranty and enterprise-class support versus 2-year warranty with the standard support for the Barracuda.

Two new versions 2.5-in version provides the same capacities as the previous iteration that is from 146GB to 900GB with lower power use and faster performance. Savvio 10K.6 delivers upto 21% high performance than the other prior generation which matches the older drives that are sustained data transfer rates.
This drive offers up to 900GB storage in a small form factor which is 50% more capacity by using 70% less space than the highest capacity 3.5-in 15K drive. Delivers a staggering power consumption reduction of upto 71% which is compared to 15K-RPM with 3.5-inch drives and up to14% compared to the prior generation. The Savvio 10K.6 also offers AES 128-bit and 256-bit encryption. This drive is currently being reviewed by the U.S. National Institute of Standards and Technology (NIST) to determine whether it meets FIPS 140-2 Level-2 certification. Users are expected to be available by mid of 2013.
