Storage is somewhere 'stuff' that was once useful goes before it goes to Recycling.
Are all 'self-storage' vendors the same? Pretty much so.
IMHO, the same goes for these 'data storage' vendors.
Wake me up when
1) It becomes affordable, and not just for the mega corps.
2) These companies are NOT hoping to get bought out so that the current owners can retire
3) What they are peddling means something to the average IT bod. Not some snake oil that promises lots but delivers nothing but an upset stomach when sampled in large doses.
