Hitachi Deskstar 7K1000
By VARINDIA - 2010-03-30
Hitachi Deskstar 7K1000 hard disk drive delivers up to one terabyte of storage capacity for demanding consumer and commercial computing products. It leverages the industry’s most reliable perpendicular magnetic recording techniques and the latest advancements in silent acoustics,shock protection and head technology to maximize capacity, performance and field reliability.
The Deskstar 7K1000’s has second-generation PMR head and media technology improves noise characteristics and thermal stability.
Hitachi achieves its huge capacity by packing 200GB onto each of the drive’s five platters; that’s up from 100GB per platter on Hitachi’s 500GB model. The Deskstar 7K1000 is Hitachi’s first 3.5-inch drive to use perpendicular magnetic recording to record data.
The drive is the fastest on our file search test. It required just 151 seconds to search for a text string in the 11.7GB of content we placed on the drive. The new Deskstar tied for top honours on our ACDSee test, taking 513 seconds to do perform our scripted tasks of searching and converting files from one format (say, .jpg) to another (say, .gif); and it sailed through our WinZip test, shaving two seconds. The drive’s performance was slightly less impressive on two other tests: copying files and folders, and copying very large files. Here, it took 144 seconds to write 3.06GB of files and folders), and 117 seconds to write a single large 3.06GB zip archive.Deskstar 7K1000 features three advanced low-power idle modes – active, unload and low-power. Together, they reduce power consumption at the drive level up to 20%, optimize non-operational latency and lower drive temperature for cooler system operation. In low RPM drives, this can reduce power by up to 50%. Ramp load/unload provides tangible benefits for the drive and host product. It greatly minimizes the risk of shock damage by eliminating direct contact between the heads and disks. In the event of power loss to the drive, heads are unloaded using energy extracted from the spinning disks. This patented power-saving feature helps to reduce overall maintenance costs and extends the drive service life.
Deskstar 7K1000 has an integrated thermal sensor monitors operating temperature, enabling the host processor to intelligently adjust airflow as needed for cooling. Sensor integration reduces component cost and increases reliability. Deskstar 7K1000’s iridium-manganese-chromium (IrMnCr) read head sensor technology offers better performance and reliability in harsh conditions.
