Speed of a 2TB 7200 drive on FW800 vs. RAID5400 on TB

Basically, I would like to find out, how the speed (read, write and transfer) compares between these two options:
1.) single 2TB 7200rpm desktop drive hooked up by FireWire 800
2.) dual 1TB 5400rpm laptop drives (2TB with RAID 0) hooked up by Thunderbolt.
Reason is, I had been using an external 2TB drive for media on my MacbookPro, connected by FW800.
I am currently using a MacBook Air, which obviously does not have a FW800 port, so the drive is hooked up by USB 2, which is extremely slow... specially when backing up the media drive to another 2TB disk.
I would like to purchase a LaCie Little Big Disk Thunderbolt drive to use as the media drive with the Air. The LaCie drive houses two 5400rpm laptop drives I believe, in either RAID 0 or RAID 1 configuration.
I need to make sure, that I get comparable, or hopefully faster disk access with the upgrade.
In my thinking - I might be wrong -, the RAID-0 would offset the speed decline of the slower rpm laptop drives, while the Thunderbolt connection would give quite a boost over the FireWire 800 connection used in the old setup.
Any ideas? How would these compare as far as data access, read, write and transfer when doing backup?
