Signaling that 6TB hard drives are no longer for the exclusive enjoyment of expensive enterprise-level setups, Backblaze has crammed 45 of the drives into a single enclosure to create what we believe to be the highest-density storage pod ever created -- 270 terabytes of spinning platter joy in a 4U rack-mount chassis. Better yet, if you have about $15,000 to hand and a penchant for computer building, you could even build your own 270TB storage pod -- Backblaze open-sources its hardware designs, so you can simply follow along.
