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:
- Two 1 TB Western Digital drives
- 7200 RPM
- 32 MB cache each
G-RAID with 2 TB storage:
- 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.
