Performance of eSATA over PCIE vs. Firewire 800?

[timlevin]

Does anyone know how the performance compares between (1) an external hard disk connected with eSATA, through a PCIE card, and (2) the same disk connected directly to Firewire 800? Is there some data about this?

FW800 will be around 60 mb/s max while eSATA will be as fast as the harddrives allows it to (current 500 gb / 7200 rpm 2.5" drives reach around 110 mb/s max).

I usually get ~77MB/sec out of FW800. My disks max out before they can saturate eSATA, but it is theoretically capable of 250MB/sec on the expresscard bus (2.5 gigabit). I've seen over 130MB/sec sustained to my 1TB disks.

The Sonnet Tempo Edge eSATA card seems to be able 125MB/sec read and 110MB/sec write. The expensive Sonnet Tempo Pro is capable of up to 200MB/sec.

Are you gonna use one normal (not SSD or Raid) external HD?
In that case the speed differences won't be much.

I have two HDs, a 1TB "black caviar" western digital and a 1TB Seagate 7200.11 in a single external enclosure connected by a (eSATA/FW/USB) cable. Since there are two HDs driving the data, perhaps eSATA is a better choice?
