Data integrity is a hardware problem, not an OS problem.

The myth that Linux is stable enough that you don't need ECC unless you're running ZFS or a database is wrong. A flipped bit corrupts memory before the OS sees it.

-ECC protects the OS. The OS cannot protect itself.

Windows has the most aggressive consumer‑grade fault‑tolerance stack with WHEA, bad‑page retirement, PCIe AER recovery, GPU/driver subsystem restart, VBS integrity enforcement, core offlining, and memory poisoning.

-These features dramatically reduce crashes on unreliable hardware.

ECC is the only one to detect single‑bit errors, correct single‑bit errors, detect multi‑bit errors, and prevent silent corruption from propagating. It's not 'Linux stability' - it's literally ECC (which most consumer desktops and laptops don't have)!

-Servers need ECC because server workloads demand correctness (and Linux doesn't even try to deliver that because they don't have to).

Cosmic rays, electrical noise, and manufacturing defects literally hit hardware, not software. -That famous blue screen in front of an audience during a Windows presentation? -Nothing to be ashamed about (but they could've used ECC)!

If the hardware lies, the OS has no way to know. Even Windows Server requires ECC. Enterprise Linux distros recommend ECC. It's about physics: not the OS.
