Is ECC memory any use?

[Timothy Murphy]

I'm getting memory for a very old (P2B-LS) Asus motherboard,
and I see I can get ECC memory for some 20% more.

Is there any point in getting this?
I see there is quite a lot of work
in getting ECC testing incorporated into the Linux kernel.
But even if it were there, would it be very valuable?

I have a feeling that disk errors are far more likely
than RAM errors.
Is that right?
