There is a related question here.
I have a WD MyBook 1TB external disk, and I connect it to my computer using USB. Since I travel quite a lot, so I bring this MyBook with me, wherever I go.
The issue is that I don't know whether using USB ( the MyBook comes with external SATA connection, or something like that) is good for the external hard disk and my computer. I afraid that the USB may be prone to failure, and that somehow will kill my external hard disk performance or worse, make either the external hard disk or my computer die faster.
Is my fear warranted? My experience with external hard disk encased inside a simple casing is very bad; the external hard disk broke down very often. That's the reason that prompted me to buy MyBook. I don't wish to see the same thing happens to MyBook.
