Storage can be as reliable as you want, you only need to throw parity at the problem. Flash is one of the most unrealiable technology today, chips are ofter rat

Storage can be as reliable as you want, you only need to throw parity at the problem. Flash is one of the most unrealiable technology today, chips are ofter rated at only 10000 writes before bit-errors, flash is used as storage today thanks to advanced Error-correction (ECC) algorithms. BTW spinning hard-discs also use ECC since many years ago but it is much less powerful.
