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.

...I have previously purchased a Freecom 500 GB external drive drive and have been very happy with it's performance and reliability. So when the drive started to become 80% full it was time to look for some additional storage. I saw the new Freecom 1TB drive on Amazon and given my previous good experiences purchased one straight away. It arrived this morning (Tuesday) having ordered in the previous Friday, and all of this post free.
For anyone that hasn't bought a Freecom external hard drive before, you get a very stylish drive unit, power adapter, leads and installation disk. Installing (in my case) took less than 5 minutes, most of the time was spent unpacking the pieces.
Simply attached the usb lead, power pack and switched on. Instantly recognised by the Windows XP operating system as the next drive letter.
The unit is virtually...

Advantages: 1 Terrabyte Disadvantages: not portable - but who cares
...This is a bargain that i couldn't pass up without buying. 1TB should keep me going for several years and more.
I bought this hard drive for £101 and it has been a pleasure to use. It's a doddle to set up and install and the fast rate of transfer makes file sharing very efficient and easy.
Design
The portable hard drive comes in an attractive silver case that has USB2 and FireWire 400 ports. It is a desktop drive and cant really be moved around due to its size.
Installation
The instructions were easy to follow and it installed by windows wizard as soon as i plugged it in, so within 20 minutes i was backing up my files.
Performance
Performance is good for a portable hard disk, and there was no real difference in speed between the two interfaces. T
Features
It doesn't ship with backup software, just file...

Advantages: Very fast, high capacity. Disadvantages: Pricey, may be outlived by long-life Blu-ray discs.
...megabit compatible), an on/off switch (which also has an auto setting) and a rather curious, possibly James Brown inspired "Func" button. There's also a ghettoblaster style mains socket and a 40-50mm fan grill. The fan is a little bit noisy but you wouldn't notice it in our server room. It's also drowned out by the sound of the drives when their in operation. There's also a wonderful silver panel on the front of the unit with ultra-low profile status indicators for power and network.
A quick look under the hood reveals two Hitachi deskstar 1TB drives which are mounted at the front of the case. This is a joy to see as Hitachi drives are my personal favourites after a review I saw showed they were almost on a par with Western Digitals Raptors in terms of speed, but with decent capacity and a lower price tag. The drives are linked by a single...

There is only so much I can say about the hard drive in terms of use. Basically, a hard drive is a hard drive and this functions as well as any other. However, I have had no problems with use of the drive or loudness. The hard drive excels in it's... more
