Networking Two Computers One Raid Drive

I've got a Lacie 4big Quadra Raid Drive which I want to access from two lap top computers. One computer is a Dell E4200 and the other is a Dell D800. Both computers are running Windows XP Pro. There will be no internet connection and the entire set up will be on one desk. Minimum power consumption is essential.
If you need more information that would be helpful I will be happy to supply it.

Thank you.

 

Connect the Lacie via esata to the e4200, once it is recognized, explicity share it and give access to EVERYONE account. Set up an adhoc wireless network between the two laptops by assigning ip addresses in the same range and in the same workgroup. Map the Lacie on the D800.

Note: that is the cheapest, most energy efficient, but the connection between the two will be slow--assuming you are using the only available wireless option on the D800, the max bandwidth would be 56mbps, but you are more likely to see much slower speeds. Personally, I'd opt for a small switch

 

The Lacie is recording video files, wouldn't a wired connection between the computers be faster and more power efficient?

 

much faster....but not more power efficient since you need to power a switch

OR you could use a crossover cable and eliminate the switch, which I suppose would be a good alternative.
