Not the first time that has been suggested/mentioned in these forums. ;)

Unfortunately, the answer is always that a UPS is not an adequate replacement for a proper SLOG with PLP. Other factors can come into play that are outside of the UPS' Control like Power Cord(s) knocked out, PSU Fault, System Freeze, etc.

The only other *viable* suggestion I know of is using an actual Hardware Raid that has a BBU to attach a SLOG to. I first saw this mentioned by @jgreco as an "unorthodox alternative for SLOG" in this thread (which is a highly suggested read).

However, in the end I would still opt for having a SSD with PLP.

Okay, so better to use the UPs (as its better than no ups at all), until I get the Intel S3700.

Yeah, you should always have a UPS regardless. Just as important to have it properly configured too. :)
