Would having to perform a Secure Erase every hour, day, or even week really be the most cost effective use of an administrators time?
You're assuming that the "into an empty device" performance is required by their application. For many users, the worst-case steady-state of the device (6k IOPS on the Vertex2 EX, depending on workload, as per slide 48 in your presentation) is so much faster than a rotating drive (50x faster, assuming that cache disabled on a rotating drive is roughly 100 IOPS with queueing), that it'll still provide a huge performance boost when used as a ZIL in their system. For a huge ZFS box providing tens of ZFS filesystems in a pool all with huge user loads, sure, a RAM based device makes sense, but it's overkill for some large percentage of ZFS users, I imagine. -- Eric D.
