1394 Trade Association Announces FireWire 3200 - Page 2

Wikipedia says the maximum cable length is 2m (a touch under 7').

eSATA is specified for a maximum cable length of 2 meters:

Serial ATA - Wikipedia, the free encyclopedia

Not sure if anyone offers repeaters, as they do for firewire, or if there are any technical limitations that would make it impractical to do so.

Well, with gbE you get ~125MB/sec, if you teamed two ports you'd hit 250MB/sec - I think that would be sufficient. You do have to keep it down to 100m runs though

Unacceptable!!!

Ok, go with fiber, you'd might need repeaters every 50 km or so (can't recall the actual numbers anymore). Better?

Getting there, at least.

This is something I thought of years ago. One HDD internal to a PC has the OS, then all your other HDD's are in eSATA enclosures that you swap into 2 or so slots on the tower with eSATA and power links. With AHCI you can hotplug them while keeping the xfer rates of SATA. If the slot design and form factor are standardized, you can take your drives to anyone else's PC and plug in.

Unfortunately, standardizing anything on PC seems to rub against just about everyone.
