Summary: With its 1-terabyte capacity Hitachi's Deskstar 7K1000 brings a new meaning to the term mass storage. But how does it perform? Time for Alexis to find out!
Today we’re taking a quick look at one of the biggest hard drives you can find on the market, the Hitachi Deskstar 7K1000 1 Terabyte drive. The spec sheets are pretty impressive:
The Deskstar 7K1000 is rated for 50,000 start and stop cycles, which is the same as drives rated for 1.2 MTBF, but they do not advertise a specific MTBF for this drive. This is on par with Western Digital’s RE2, RAID optimized, drives.
Hitachi claims that their five platter design used on the Deskstar 7K1000 improves reliability since it doesn’t push the bit densities. In contrast, Western Digital claims their four platter design improves reliability since it has fewer parts. Samsung says that they are even more reliable with three platters on their 1TB drive.
We tested the Hitachi drives in a Windows Vista x64 software striped RAID configuration using both HD Tach and SiSoft Sandra benchmarks. These tests were done on our 8-core Intel V8 reference system, using SAS/SATA onboard controllers.
We compared the 1TB Hitachi drive head-to-head with our Seagate 0.75 TB ST3750640AS-RK drives. Both are on the cutting edge of magnetic recording media, with perpendicular recording and SATA II. We did not have Seagate’s latest 1 TB 7200.11 drive for comparison, the Seagate 7200.11 came out about 6 months after the Hitachi Deskstar 7K1000, but does boast a 5-year warranty and a four platter design.
It is just a matter of time before you will need a 1TB hard drive. A few years ago, we wrote a huge article about our 1 TB storage server with four 250GB drives. Back then, 1 TB was a lot of storage. Today, when building your next mini-pc or HTPC, you can put 1TB of storage in the same form factor. With eSATA slowly gaining popularity, the days of needing dedicated storage servers may be passing, at least for the home or home office.
