may try the multiple hard drives, but from all of what i heard doing a RAID stripe is not the way to go for my machine. i didnt buy the hardware RAID/SAS card (which was like a $1,000 option YIKES 8| ), and the software raid leaves alot to be desired when raid-ing for performance reasons.

the SSD drives are very appealing because there are no spinning platers, or moving read/write heads. they offer slightly better throughput in data transfer, but HUGE improvements in random access times. but again, the 64gig SSD drive option in the macbook air is a $1000 option also. for that kind of money i can buy 4 1tb drives, and each WoW can have its own drive to load from, and i can have 4.5tb of storage, LOL.

Hmmmm, i have a few bestbuy gift cards that i need to use up. argh..... choices, choices.
