I'm looking for advice from the I/O gurus who have been in the SSD game
for a while now.

I understand that the majority of consumer grade SSD drives lack the
required capacitor to complete a write on a sudden power loss.  But,
what about pairing up with a hardware controller with BBU write cache?
Can the write cache be disabled at the drive and result in a safe setup?

I'm exploring the combination of an Areca 1880ix-12 controller with 6x
OCZ Vertex 3 V3LT-25SAT3 2.5" 240GB SATA III drives in RAID-10.  Has
anyone tried this combination?  What nasty surprise am I overlooking here?

Thanks
-Dan
