ECC RAM vs non-ECC RAM for N100 home server: Non-ECC is fine
Non-ECC RAM is fine for your N100 home server because the odds of a bit flip corrupting a file are astronomically low, and the N100 doesn’t support ECC anyway. ECC is for high-availability or data-critical environments like financial databases, not your occasional-use media server. Focus on backups and a UPS instead.
