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
