This isn’t the most detailed or controlled test but on a whim I used InTech SpeedTools to benchmark two external drives attached to my MacBook Pro via FireWire 400: OWC/NewerTech Guardian Maximus (DIY kit) and the G-Tech G-RAID.

Guardian Maximus (DIY) with 1 TB storage:

• RAID-1
• Two 1 TB Western Digital drives
• 7200 RPM
• 32 MB cache each

G-RAID with 2 TB storage:

• RAID-0
• Two 1 TB drives
• Speed and cache unknown

GMax results using Extended Test (20-100 MB):
Read = 38 MB/sec, Write = 36 MB/sec

G-RAID results using Extended Test (20-100 MB):
Read = 39 MB/sec, Write = 36 MB/sec

I’ll whip up some FireWire 800 tests at a later date.
