Seagate Reinforces 3.5-Inch Drive Line

Arthur Cole

Seagate is bucking the trend away from large disk drives with a pair of 3.5-inch additions to its Cheetah line aimed at Tier 1 storage environments.


The new Cheetah 15K.7 and Cheetah NS.2 are aimed at performance and power consumption, with an eye toward driving down the cost per GB in the hopes that cash-strapped enterprises will hold off on SSDs and less-powerful 2.5-inch drives a little longer.


Both drives offer largely the same specs: capacities of 300, 450 and 600 GB with 16 MB caches, plus 6 Gbps SAS 2.0 and, except for the 300 GB NS.2, 4 Gb Fibre Channel interfaces. Seek times are as low as 3.4 ms for the 15K.7 and 3.8 ms for the NS.2, and both drives have MBTF ratings of 1.6 million hours.


Both drives also feature the company's PowerTrim energy optimization technology that lowers the draw some 20 percent over previous models. They are also available as Self-Encrypting Drives for OEMs dealing with high security requirements.


The NS.2 is available immediately, while the 15K.7 ships next quarter.
