Answer 1

Something you put everything together and got a delicious porridge!
If the hammer is green, will it be good for hammering nails and showing the news at the same time?
In this issue, only hard drives are discussed, not 32GB memory.
You will have enough memory for your eyes only if you do not have a highly loaded cluster of 1 million sites!

Answer 2

ECC memory is a bit more reliable:
It costs more because it contains additional memory for storing ECC and error control and correction circuits.
Supported mainly by server hardware.
