Well, to answer my own question ... none of the above; it's RAID 4, which I haven't run into for a while. So, the question then becomes whether one can truly trust the NVRAM cache. What they say sounds good, but then vendors have been telling us for years that their write caches were completely safe and it was a lie. Given the sophistication of the rest of the product, I will assume for the present that it is safe and that this masks the potential performance penalty for writes, but were I buying one, it is something I would want to look into more deeply unless I found a source I could believe.

So, let's turn this upside down and say that it seems to be a potential advantage of NTAP that it seems to provide RAID 4 protection, but unlike virtually every server-attached RAID controller, it can be safely used with the cache enabled in a RAID 4 or 5 mode.
