... the review benchmarks I've seen don't show eSATA with much advantage over FW800.
That's been true in the past, but until very recently, high-capacity HDs
weren't fast enough to saturate a FW800 link on sustained transfers.
However, the latest big drives (e.g., Seagate's 7200.11 series) can
schlep >100 MB/s across the heads -- and they're only going to get
faster as perpendicular recording densities increase. The 7200.11's
are Seagate's second-generation P.R. drives, and they're
35%
faster than the first-generation 7200.10's (105 MB/s vs. 78 MB/s).
Also, a dedicated HD interface has huge performance advantages
over a shared firewire connection. Firewire disk performance takes
a big hit when you connect a camera, camcorder, or audio source
to the bus. The benchmarks never show that.
