Manufacturer's product description
The Ultrastar A7K1000 features a 3 Gb/s SATA interface supporting key features in the Serial-ATA specification including Native Command Queuing (NCQ), staggered spin-up and hot-swap capability. The Ultrastar A7K1000 allows for configuration scalability and with the same physical connector as Serial Attached SCSI (SAS) drives, it's ideal for use in mixed-drive environments. In multi-drive environments, rotational vibration, which results from the vibration of neighboring drives in a system, can degrade hard drive performance. To aid in maintaining high performance, the Ultrastar A7K1000 incorporates enhanced Rotational Vibration Safeguard (RVS) technology providing up to 50% improvement over the previous generation against performance degradation, leading the industry.

Although most people wont need a hardrive this size to do the basics of any office applications or internet use. This hard drive is for the people who run network drives and do alot of video editing and the like.

Advantages: Quite, low power consumption, high capacity Disadvantages: Expensive
...I have been using a Hitachi TravelStar for a long time now, I have had not problems with it and I have given it a good run for the price I paid for it.
I originally started out with the 80gb model of this hard disk. I had absolutely no problems with it. (I now have the 100gb model as the laptop it was in was broken in a car accident).
I had the 80gb model for a year and never gave me any trouble. It was:
· Fast
· Reliable
· Quite
· Super low power consumption
· Had a quick spin up time
· Very quick seek time
· Standard 5 year warranty
· Very helpful warranty/customer support
Hitachi's customer warranty claims support is like no other that I have come across before. You go onto there website, fill out a warrant claim form; package the device (hard disk in my case) in the way they require. Once you have sent it to them...
