...helps this drive compeet with faster drives (WDraptor 10krpm) but for around £50-60 knock 2 of them in Raid-0 and you will most likely have a very large, very fast drive setup for £40-50 less than a faster drive!
I would suggest if you're in the market for a large, reliable, quitet drive you realy do need to look at Western Digital's 250GB SE16 Drive as this drive ranks at the top of the hard drive food chain, and is industry standard coming from WD who are renowned for their quality and the life span of their products.
Western digital SE (special edition) is another way of stating that this drive has 16mb of cache instead of the usual 8mb (overall faster performance for sustained use, ie network storage)
The drive spins at 7.200RPM (rotations per minute) which is usualy classed as the norm for higher end hard drives, where...

...If we look at the name of this device, 'Western Digital Caviar SE16 WD2500KS 250 GB', we can infer a great deal of information. 'Western Digital' is the manufacturer, 'Caviar' is the produce line, 'SE16' tells us that this is a special edition device with a 16Mb (1Mb = 1024Kb, 1Kb = 1024b) cache, 'WD2500KS' is the model number and 250Gb is the device size in raw data format.
Western Digital are a good company and in fact I buy all of my hard drives from them because they have never failed on me. The Caviar device line has been in operation for about six years and has included IDE devices as well as the newer SATA and SATAII devices.
The special edition bit of that means effectively nothing, it is simply a marketing thing, but the 16Mb cache is very important. Normally hard drives have an 8Mb cache and used to have a 2Mb cache...

...What is there to really say about hard disc drives? Well that depends on your audience I suspect.
Oh yes, yes it does.
If I were talking to a bunch of tech-heads (bless our geeky hearts), I would say this;
This is a standard SATAII device that displays speeds of;
23.7Mb/s = sequential read
56.8Mb/s = sequential write
And they would know just what I meant.
I think however that some people may want a little more as as such I'm going to explain a lot in the coming paragraphs about connectors and bits a pieces and installation etc.
So, this device is a SATAII hard disc drive. This means that it has a theoretical maximum transfer speed of 300Mb/s and is used for storing data, it also means that it is incompatible with IDE systems and will only work on newer SATA capable systems since it is SATAII. However fear...

The 'WD Passport' series of portable hard-drives are a solid option for anyone. They look good, they are small and robust, and have good capacities that read and write at an acceptable speed. Connecting via USB they should pose no problem for people... more
I really do love Western Digital hard drives as they deliver great performance and storage at very reasonable prices. This is no exception.
This is a very cool and compact metal-cased storage device that works as well as you would expect from Western... more
I am glad to see such a reliable brand name as Western Digital finally producing a USB Powered external hard drive - Thats right these drives require no power adapter they are powered directly through the USB cable (imagine them as very large USB memory... more
