Before we get into the Deskstar 7K250's performance, let's have a look at the drive's spec sheet.
|Maximum internal transfer rate||757Mbits/sec|
|Maximum external transfer rate||150MB/sec|
|Average sustained transfer rate||61.4MB/s|
|Average seek time (read)||8.2ms|
|Average seek time (typical)||8.5ms|
|Average rotational latency||4.17ms|
|Available capacities||80, 120, 160, 250GB|
|Serial ATA interface||Marvell 88i8030 bridge|
|Warranty length||Three years|
The 7K250's specs are pretty much what one would expect from a modern 7,200-RPM Serial ATA hard drive. Notice that Hitachi covers the drive with a three-year warranty. That fact should offer at least some peace of mind to those who have fallen victim to the old Deskstar GXP-series' propensity for click-of-death failures. Of course, a warranty can't rescue data from a dead drive.
Like most hard drives, the 7K250 isn't anything special to look at. In fact, the drive has a striking resemblance to a couple of old Deskstar 60GXP drives I have kicking around the Benchmarking Sweatshop.
Unlike my old 60GXPs, the 7K250 is available with a Serial ATA interface. The drive also comes with standard Serial ATA and four-pin Molex power connectors, though Hitachi cautions against using both power connectors at the same time; doing so will apparently result in drive failure.
Flipping the 7K250 reveals a printed circuit board with a smattering of chips.
