Topicbox-Message-UUID: cc853b2c-ead9-11e9-9d60-3106f5b1d025 Hey, thanks for explaining. this usage is surprisingly valid. I have some much much older kirkwoods for the same scenario. The benefit is: gigabit ethernet, higher stability, case included, power supply included (and no power problems as on rpi), lower price. I boot them all from USB HDDs, but I see how flash would save more power. Carry on! :) The main disagreement in this thread is calling all kinds of different flash storage "SSD". common usage reserves this name for the sata or more recent nvme disks that actually are much more stable, in my understanding due to better controllers and their better wear leveling algorithms. With sd cards and usb flash drives you are lucky if your 128GB stick is not really 1GB flash with %1GB "wear leveling algorithm" where after 1GB you rewrite your already saved data :D It's a low-end market with shitty margins, low quality controllers, and in general too many counterfeits, even from good shops and big retailers. so you can't even depend on the company/brand/product name. Privately I never had surprising problems with HDDs, I don't manage to fill enough to notice the small risk in practice. All my old HDDs still work. They are only unused cause they got too small to be worth spinning any more (waste of power). I project my SSDs will not fail before i get 10/40gbit connection to my NAS. Till then my write wear will be limited by my low bandwidth and high latency practical use cases. On 2/4/18, Digby R.S.
