You may have heard that RAID is no longer applicable for enterprise storage: that it’s time had passed. RAID has dominated enterprise storage for decades and, while not a hot topic of conversation today, it remains a key strategic approach for businesses to consider. To some degree, it is true, RAID is no longer the singular answer to enterprise storage that it once was.  For decades it was unchallenged as a technology and as an approach, and so reigned alone – a foregone conclusion in a giant sea of storage.  Today, RAIN has joined the space and is a viable alternative to RAID in many scenarios.  But just because RAIN is newer and the darling of storage conversations does not mean that RAIN will simply displace RAID nor that RAID’s position of importance has been eliminated.  Not at all.
