The Hitachi 7K3000 has a rather clean appearance with its silvery top panel and black on white drive sticker. Hitachi doesn’t put a huge emphasis on advertising their brand name on the drive itself, where others like Western Digital even color coordinate the drive with the brand logo displayed prominately.
The front of the 7K3000 includes the standard SATA power and data connection, with a single jumper section. No mention of the jumper pins are given on the drive cover, although one of the Hitachi service manuals make note that it is used to enable Power-up in Standby. This is primarily used to minimize startup power requirements of a computer as a whole, by allowing the controller to sequence how the drives connected to it are powered up. Instead of having a handful of drives all spinning up at the same time, the controller can stagger the spinup sequence.
The bottom of the drive is fairly basic, following the design of having the main circuit board components facing inwards. This allows certain parts to shed heat into the drive body for better cooling management as well as preventing components from being knocked off when roughly handled.
This test focuses largely on the read performance of a drive. The Hitachi 7K3000 beats both Western Digital drives in this test without question; its high platter density is definitely a factor though probably not the sole factor; the storage controller and the drive’s firmware also come into play.
- Very high capacity
- High platter density
- Excellent overall performance
- Slightly higher than normal power consumption
- Can’t match Western Digital’s warranty period (3 vs. 5 years)
