Just had a UT2 delivered and need some SSDs to go in it. Don't care about speed (its only Gen-3 capable and is mostly going to be used for backing up SD cards out of my cameras, so I/O benchmarks are all but irrelevant). However, while not the primary use case, I would like to have the option to do a backup on battery power, so I need power-efficient SSDs.

I found a few old-ish posts elsewhere suggesting the Hynix P31 Gold, but as that's a few years old and doesn't go above 2TB, I'm assuming there's probably something better by now. 2TB is probably fine, but I'd consider 4TB if it doesn't break the bank too hard.
 
Battery isn't great, maybe 20 minutes under load, but I can usually dump an SD in 5-10 minutes, so enough. I do usually carry a 100W-capable PD power brick with me, so most of the time it won't be on batteries anyway. They do warn that the battery can't reliably power some 8TB SSDs, but my wallet can't afford them either, so that's fine.

Hotel I stayed at last time didn't have enough bandwidth to dump everything to cloud before I came home. I did have a Crucial X9 with me so ended up copying everything to that, which worked but requires a laptop.

Thanks. Getting consistently good reports about the P31 and if it was available in 4TB it probably would have won already. As for the PM991/a, it looks like a 2242 part. I'm aware that adapters are available but the device only has mounting posts for 2280. Also couldn't find capacities above 1TB for that.
