I have yet to see a drive that includes battery backup in it, and I work at a place that spends millions of dollars a year on enterprise grade storage
I think this is a myth like the drives that use platter energy to power themselves to write their buffer.
if you can point to a drive that includes a battery backup on the drive please post a link to it.

I suspect aliguori is referring to disk-array boxes, not drives.

Even then... it's just occurred to me that while I know my Areca RAID
controller has its own battery-backed cache, I have no idea whether it's asked the drives it controls to turn off *their* internal write cache... (Obviously we don't want that cache, as it's not battery-backed in any way.)
