It seems like this a big stretch of the truth on their part. If you have let say 30TB of data hosted in the cloud and wanted to use this. Not on would you need a RAID yourself so we're talking probably 4-6 high capacity drives at around $500 a piece, but additionally you'd need around triple that to match the redundancy of cloud storage. Additionally you'd need someone capable of setting up a shared file system and fiber between all the access points. We're talking probably around $12,000 upfront and monthly bandwidth costs of $750. That or you can get unlimited storage from Google for around $120/mo, maybe much less. Many people still only pay around $12/mo.
