What I'd like to see is:
1) Data on which SSDs have supercap
Every SSD review I've read at Anandtech.com or StorageReview.com has mentioned the presence of a supercap on drives that have them.
When they review consumer-oriented drives without the supercap, they typically don't say "there's no supercap" but 1) there are usually physical teardown pics so you can fairly easily check for yourself 2) be pretty sure there isn't one if they don't mention it, because they always talk about it if there is one.
This doesn't help with this, of course:
2) Data on which SSDs actually honour cache flush request (then a UPS + forcing a cache flush request upon power failure + redundant power supplies/multiple replicas in a distributed system) would suffice.
Would love to see reviewers test that as well. For now it seems like there's no way to know unless you're willing to do your own power-cycle torture testing.
