Still a lot of time to recover it...

Right, but you are protected against a read failure during rebuild of a
single drive. I have 14 drives in Raid6, and keep meaning to drop a
15th drive in as a hot spare.
I worked in the enterprise storage array market, and know the issues
with raid technologies (in fact, the array I support uses a distributed
mirroring system, www.xivstorage.com)

This are the issues that keep me away from hardware raid adapters. I
use Linux software raid, and I can re-assemble almost anything with it,
and have even had to get a Raid6 up and running from a tripple drive
failure (Seagate firmware issue), and it was not too painful.
