Ugh, Anandtech explains that their marketing is misleading, that drive

I've been trying to figure this out in part because I wondered what I
might use if I replaced my home server this year. After some further
looking the cheapest PCIe-attached SSD with real power loss protection
that I've found is this Intel model a little over $300:

Kinda ridiculous to buy a 450 gig drive mainly so I can put a half-gig
journal on it. It might turn out to be best for my case just to RAID a
couple of those SSDs and skip the conventional drives completely.
