Hitachi Deskstar 7K1000 1TB HDD Review
Advertisements
More storage in lesser space is what this hard disk drive will, and that too with good performance and at a great price. Look like a new era of a high-capacity drives is just round the corner
With Deskstar 7K1000, Hitachi offers a hard disk drive with a whopping storage capacity of 1TB. So now you can have higher capacity NAS boxes with sleek designs. New high capacity file servers could be built out of these. It could even be used in disk-based backup appliances. This drive supports SATA II specification, which enables it ti deliver 3 Gbit/sec. It has a buffer memory of 32 MB. Which reduces the number of accesses to the hard drive, thus improving performance? Hitachi 7K1000 uses Perpendicular Magnetic Recording (PMR) technique, where in the data bits are arranged perpendicular to the same form factor. Actually, it’s a 931.5 GB hard disk, as your OS will report this much only, because the system uses the binary approach where 1 KB equals 1024 Bytes and not 1000 Bytes, as used by vendors.
This drive gives silent acoustics performance and has 3 low power-idle modes to boost power efficiency. Hitachi has used five platters for the 7K1000, each having about 200 GB of storage capacity.
As for the performance, we tested it on a Athlon FX 55 based machine with 512 MB DDR RAM. We ran the business Disk and High-end Disk Winmark tests of the Win Bench 99 suite, which are used to check a drive’s throughput for business producativity and high-end applications, wherein it scored 18.2 MBps and 44.2 MBps, whichare far better than Seagate’s Barracuda ES 750 GB drive (reviewed in August 2006) that had scored 18.3 Mbps and 28 Mbps, in these two tests. Besides, this drive also gave a lower (better) access time of 11.4 ms as As this being the first 1 TB HDD, we ran other benchmark test also apart from WinBench 99 suite. This HDD gave an average transfer rate of 70MB/s, which is good. Quite impressively, the tests showed its burst rate speed to be at 200MB/s, thanks to the 32 MB buffer memory (see performance chart).
The usage of five platters affects the drive’s response time but, it increases the operating temperature. The drive temperature reached upto 59?C, when we were running thes tests.
PRICE:Rs18,500 (yrs warranty)
Key Specs;1TB, 7200 rpm, 32 MB buffer, SATA ll, PMR technology
It’s a good buy for anyone who is looking for one high capacity drive.

However, despite the test scores and the novelty of the drive’s size, everyone knows that Hitachi shouldn’t be making hard drives anymore, too many are DOA and don’t last quite as long as the rest.
