> Broadly speaking it costs as much to look after 1TB of data as it does to look after 0.1TB of data.

That's broadly true, when 1 TB is approximately the standard size of a disk.

However if you want to store ten times that much it suddenly becomes a lot more difficult - getting 10 TB of server grade storage into an off-the-shelf server chassis is hard and expensive.

FWIW, HP's largest "standard" disk for a DL380 is 600 GB, and they're 400 quid a pop, not 40.  Hotplug and 10k RPM adds a _lot_ to the price.

However, achieving 50% compression and reducing storage to a mere 5 TB gets the price and complexity back down to a reasonable level.
