SSDs 'reduce power consumption'

02 Jan 2009

Solid-state disks (SSDs) are high-performing drives which contain their own central processing unit to manage data storage, meaning they produce the highest possible input/output (I/O) rates.

Such are the claims of Express Computers Online, which notes that SSDs are most suited for applications that have high transaction rates and which require the quickest possible storage of data and retrieval speeds.

Indeed, SSDs are faster than traditional hard disks because they have no moving or physical parts and are based entirely on flash or non-volatile memory, the resource continues.

The technology is most effective when I/O response time is crucial, especially in server applications and systems, while data placed on SSDs should include authorisation and login information, databases, swap files and index and library files that can create bottlenecks.

Commenting on the deployment of such drives to the IT forum, Robert Chu, vice-president of Asia Pacific Hitachi Global Storage Technologies, says: "SSDs can offer reasonable capacity levels at fixed price points. This is why lower capacity points are primarily served by SSD at relatively low prices now."

Meanwhile, Hitachi Data Systems (HDS) recently announced the general availability of its SSDs, adding that benefits included a reduction in power and cooling consumption.
