I've had a 4BDA and 4BDA2+. There are a few differences besides the RAID. Some differences may be just the two I got like the HS and mounting
The 2+ has RAID (can be regular IDE)
Diagnostic LED display on the 2+
Came with the rear panel for the extra 2 USB ports, regular one didn't
Has a HS/Fan on the NB. The regular one had just a HS. I prefer the passive model (I hate noise)
The 2+ had a nicer CPU mount with a back plate.
I think the 2+ is worth the extra $20.
