I used to think of storage as something that you don't really need to worry about firmware updates. Some companies don't even make software to update ssd firmware. I checked though and my 980 pro is the latest firmware. I remember updating it several months ago. Hope it holds up.
I have an old shuttle all in one touchscreen with atom cpu. I got it in a lot of electronics. No hdd, it powers on and shows text but gets some red lines across after a few seconds. Includes a 19v ac adapter for it. Think it has 2gb ram. Probably not a flat rate item so if you are interested pm...
