Hey mate, im in same boat, getting a Dell M90 Precision next week from the states (1/2 the price!) and i been looking into external storage. Bar if you got the money for SCSI i think the best bet is an external eSata RAID enclosure and buy 2/4 HDD's of your choice. This is very rapid and a relitively cheap solution compared to SCSI/Raptor. For example, Thecus make a good looking 2-bay eSata one
HERE but if your looking for a 4 bay or even a simple looking (probably cheaper) 2-bay one goto
VISUALUX
On the Thecus site it says upto 2x500GB(1TB) but i think this is due to time of print. Im sure 2x750 or even 2x1TB HDD's will be fine.
So 2x500GB HDD about £170/£180 (rip off britain) and the enclosure i think will be about £100ish. £270/£280 for 1TB of very fast external space compared to other solutions is very competitive and will shift your files faster than any laptop can handle them removing the bottleneck which is the HDD
'EDIT' - Found the thecus
Komplett HERE for £92.50, they sell worldwide as well
Also, the visualux as 4 (6 on 4-bay version) fans cooling whereas the thecus only as 1. In envirments i'd personally be playing at it will get VERY hot and i prefer have the piece of mind knowing theres sufficent cooling.
This is my solution and i think im correct on what i say. If im wrong anywhere, please anyone, correct me
