[kwlug-disc] Synology, and proprietary disk formats ...

[L.D. Paniak]

It brings the same kind of grief that it would for ZFS.  These storage
systems depend on the CPU/RAM subsystem for error-free calculation of
checksums for data and, more importantly, metadata.  Flipped bits in
data will ruin a file.  Flipped bits in metadata can ruin the whole
storage system (pool, volume).

In the modern world, there is no good reason for server/workstation
hardware to not have ECC memory.  CPUs, motherboards and RAM that
support ECC operation can be had for minimal premium over "regular"
hardware.  Even the low-cost options like a $60 Pentium:

or low-power Atom Avoton board:

are ECC-capable.
