Cost for cheap SAN storage where I work is £3,000 per TB ($4,500 USD) and £10,000 per TB ($16,000 USD) for the 5 year TCO. As you can imagine every request is heavily scrutinised, tape backups have to be justified etc.

If we had SSD's it would be £50,000 per TB. This is in a EMC SAN array. All production disks are mirrored locally and remotely to the other data centre. So if you ask for 1TB in production storage needs to supply 4TB. So the price jumps to £40,000 per TB.

How many time have I heard but I can go to the local PC shop and buy a TB for £100.

I agree, but numbers that David quotes are at least 10 times higher than what I hear from our ops.

There was a case in the news a while back where a doctor was charged with misuse of prescriptions. However since he had fled the country and was not expected back, the prosecutor actually dropped charges so that the large amount of storage in his case could be deleted because it was becoming to expensive to keep it. I found that a bit astonishing.

Our ops guys flex the quote depending on the IO/throughput/access profile.

Storage volume is cheap, storage performance/concurrency isn't.
I'm waiting to see what happens to those people with 4TB drives in their Hadoop clusters once they start getting a few people battering them via HIVE or comparable technology.
