"In RAID-5 you can tolerate one disk fault"

Well, that's begging the question; the claim of the linked article is that for a certain, currently realistic, size of RAID5 array the likelihood of an unrecoverable read error during rebuild is as good as certain making the redundancy useless and meaning that a RAID0 array of equal capacity is more reliable as it has fewer drives.

It's not dubious, it's a perfectly logical argument, although I can't vouch for the actual figures used in the calculation.

It's not a great argument for the use of RAID0 and doesn't seem to be intended to be but it is a strong warning against the use of RAID5 in large arrays.

I thought it was interesting.
