Hmmmm. Downvotes without comments. Classy.
This is cheap and at qty 1.
A backblaze type box is ca 12K for 135TB of storage.
Assume an interest rate of 5% and 36 months worth of repayments and the server itself is worth $725/month
It's uses roughly 1kw of power and 4u of rack space, so say you have 6/rack with a 30A rack. You can get the rack for say 5k, giving us a total rack cost/server of $833/month
Total cost/server month is $1558/month.
Total cost/gb month is $0.011/gb month.
Add in parity replication (1 in 4, 25%), $0.014/gb month.
This doesn't include compression or dedup, both of which drops cost price dramatically.
Compare that to say S3's $0.14/gb and you can see why I'd say the margins are stupid, especially at the scale they're running at.
