Those are VAT-inclusive prices, of course. I presume the storage array price
previously mentioned is ex VAT.

Fast 300GB disks are readily available, and not much more expensive than the
147GB units. For example, a 300GB 15,000RPM Fujitsu drive is £192.48, or if
you prefer Seagate, that's £245.30. So that's "only" £12k for 15TB of the
fastest hard drives that money can buy.

So yes, there's still going to be a fair bit of room to negotiate on the
price of the drive array.

Incidentally, if you built this 15TB array out of 160GB Intel SSDs - £442.17
each - then the 15TB array would set you back £41k.

(All prices pulled from scan.co.uk, so are retail prices for one-offs.)
