Seagate Begins to Ship 2TB Hard Drives with 5900rpm Spindle Speed

Seagate Technology, the world’s largest maker of hard disk drives, this week started to ship its new Barracuda LP series of hard disk drives that feature up to 2TB capacity, non-standard 5900rpm spindle speed as well as low power consumption, something that becomes rather important nowadays.

“Growing demand for power-efficient computing systems is not just a data center phenomenon as more builders of external storage devices, desktop PCs and home networking systems work to provide customers with products that combine power-efficiency with rock-solid performance,” said Joan Motsinger, Seagate vice president of personals systems marketing and strategy.

Barracuda LP hard drives are just what the doctor ordered for those, who want low-power storage. For example, Barracuda LP 1TB consumes 5.7W in operating mode and 3.0W in idle mode; by contrast, Barracuda 7200.12 1TB consumes 9.4W and 5.0W in operating and idle modes, respectively. More capacious Barracuda LP 1.5TB and 2TB consume 6.8W in operating mode and 5.5W in idle mode.

“Seagate is pleased to deliver a new low-power product line in our Barracuda family that enables system builders and end users alike to attain a higher level of environmental friendliness while cutting costs,” Mr. Motsinger said.

But very large capacities along with trimmed power consumption come at a price: performance of the new Barracuda LP drives with 5900rpm spindle speed is well below that of hard drives with 7200rpm motor. Seagate declares 5.1ms average latency and random read/write seek time of 16ms for Barracuda LP, whereas the Barracuda 7200.12 can boast with 4.16ms average seek time as well as 8.5ms random read seek time and 9.5ms random write seek time.

Barracuda LP family of hard drives presently includes 1TB, 1.5TB and 2TB models with 32MB of cache and Serial ATA-300 interface. Manufacturer suggested retail price for 2TB model is $358, 1.5TB flavour should cost $156, whereas 1TB version is supposed to be priced at $118.
