The issue is enclosures, and whether or how they contribute to product
unreliability. I have read a few reports, of certain external products
that come with their own enclosures, which fail soon after purchase.
Your choices are, to buy an enclosure yourself, and fit a drive to it.
Or buy a pre-built external. Reading the reviews on Newegg can provide
some feedback on the pre-built ones.
Things I want to see in an enclosure:
1) On/Off switch. The drive should run continuously, with no power save
mode while I'm using it. I should be able to switch it off when I'm
finished.
2) Ideally, the power supply should be inside the enclosure. But that is
not the way the industry is leaning. Many drives put the power outside,
which means it is easier to lose the adapter or cabling.
3) Cooling. I like an enclosure with a fan. And there is more to it than that.
Some have fans, but no intake vents! How stupid is that.
The fan in the bottom of this one, is one of those thin ones, and probably
won't last forever, but at least it is a fan. Many enclosures have no
cooling features, and those I'd stay away from. Especially when using very
large drives. This one uses external power, which I don't like. But since
it has a fan, I'd probably buy it.

Enclosures come in IDE and SATA models, so select the right type for the job.
