As many will know the latest version of the rasp pi supports SSD disk drives.
I have built almost every generation of rasp pi, and eventually had the SD card fail on me, becasue it was written to too many times. What happens is the failure occurs, it sits failed in the cupboard for months to a year, until I have time to re-build, then when I re-build I consider the newer version of the rasp pi. This is how I get the upgrades, at least thats way it's gone in the past.
The cost/ time involved in re-building is shattering and others like me will be relieved that decent storage is now supported.
I've lost a tonne of red node flows in the past through SD card crashes, with back ups lost in over needed data clear outs.
I am thinking a NAS using ZFS with 4 disks with some level of mirroring, ie pretty much unbreakable and SSD crash proof and definatley hot dockable; one disk fails simply push another in and it takes care of everything.
something like FreeNAS.
Prepared to spend a bit of money to get this re-building problem to go away.
Would consider 2 disks if mirroring robust enough.
Any ideas best way forward?
