What weird writing:

Blurr is four times less cheap than the comparable rotating disk appliance from Teradata. But then it is an astonishing eight times less slow.

Im going to have to say your quoting that line a little out of context.

When I first read the article, the time I got to "slow" I was wondering what I had just read. Yet the very next paragraph helps demystify the jargon.

At that point, I realised the writer was playing with the jargon and hype but in a satirical way.
