backblaze doesn't support linux or any kind of unix at all, which makes that a non-starter. and i could not find which countries they can ship to, but i am pretty sure they won't be able to ship to china without me having to pay import tax on the disk and cost of shipping back. and i wonder if they can even ship worldwide. i also have to install their proprietary software on my computer which means that despite encryption i have to trust them with my data. i'd rather not.
so sure, there are ways to get around the limitations of a soldered SSD, but so far i have not seen any that are worth the benefit of a few grams saved in the weight of my laptop. because that is what we are arguing about here.
backups are good, and everyone should have one, and they are certainly covering several failure modes regardless of whether the SSD is soldered or not. but an unsoldered SSD also covers a few failure modes that a backup doesn't cover. at the cost of a few grams of extra weight. my goal is to maximize the recovery options. so i have backups and a replaceable SSD.
the ultimate solution would be a laptop that supports two SSDs so i can run a raid mirror like my desktop. one of those SSDs could even be soldered in that case.
