Two advantages come to mind, eogmp3
, In this way you can have more hard drive space in addition to the basic limit of 2 in your machine. Those IDE drives in the machine (simply the ones connected to the IDE ports on your motherboard) are quicker because they are closer to the processor, but any external units are not all that slow, especially using a firewire to your USB port the same way you'd plug in a keyboard. (some details differ, but in essence...) Typically I'd use an external for, in the case of a 120Gb unit, 30,000 songs. Data that wouldn't require a lot of processing power as say 3D animation construction, complex games or video editing. Those I'd use the IDE drives for.
Using an external case with a drive compatible with those in your machine provides you more benefits.
- they are cooled independent of the main machine
- they can be used in the main machine at a point in the future if you so desire
- to some extent, space utilization in your room is given options.
The Maxtor & Western Digital are industry standards and you get the same benefits you get when buying a Chevrolet or Ford instead of a Sterling or an Citroen.
You can also bear in mind setting up a new system as you intend to, just putting a pair of 250GB HDD's into it at $140.00 per. (Maxtor Diamond Plus 9's, current sale price at Office Depot)
