eSATA has no need for any interposer chips between a modern SATA chipset on
the motherboard and a SATA hard drive. You can buy cables with appropriate
ends for this. There is no reason why the data side of an eSATA drive should
be any more likely to fail than SATA. (within bounds, for cable lengths,
etc) At least you can be assured that the drive will receive a flush request
at appropriate times.

I can't argue about the external power supplies, other than to say that many
external cases these days use a single +12V rail, and have a +5V regulator
on board. These are a lot better because they allow for easy replacement of
the power supply. External units which use a combined +12V/+5V power supply
are often rendered useless by a power supply failure.

Cheers,
