RAID Time Warp
-
So I know that we have been talking about RAID here (and elsewhere) for quite some time. But I normally feel like this has just been about two to three years. It comes up nearly every day (not so much here) and the information has been the same since the infamous article written in 2009 showed why RAID 5 was already deprecated by that time.
But someone posted on a thread about write holes in RAID 5 today. I remember the thread. It does not feel all that old. But then I looked at the date and it is almost exactly five years old! A full half of a decade. And I can tell from the thread that the ongoing, almost daily RAID discussions helping people understand why some RAID is bad and why others is good, when to consider which type, etc.
It blew my mind to realize that the same ignoring of common knowledge, same lack of understanding the source material from the 1990s and more has been going on likely for six or more years now. How can no one have seen the thousands and thousands of discussions on this and keep asking?
What is astounding is how much so much of the information has aged. The old Microsoft recommendations that, when misunderstood, would kind of recommend RAID 5 (they never really did, people just read it wrong and repeated it for years and it became a game of Chinese telephone) were just over a decade old back then. Now they are rapidly coming up on two decades old! And nothing has changed, people are still repeating without questioning or understanding, the old 1990s' data.

Shoutout to @David.Scammell who made that thread long ago.

Learned a lot about RAID from you, it's been fun to learn! Now can you teach me how to get a job as a hardware monkey?
