The disadvantage with multiple consumer SSDs instead of a single enterprise SSD:
1. More SSDs = more RAID controllers, which can quickly add up in a server environment.
2. Consumer SSDs are usually not designed to have insane amount of writes to them.
3. Warranties aren't as sugary for the user, which can be a pain in the rear end for an IT department.
As a consumer, I don't see a need for such blazing fast SSD. But it's sure nice to look at.

Not unless if you somehow push a HDD to 30K RPM or higher, without shattering the platter due to centrifugal force...

HDD consume more power and throw out more heat than SSD. When you have hundreds or thousands of them running, that will quickly add up in the electricity bill because of fueling the HDDs and keeping the server room cool. And even then, HDDs tend to perform poorly in random read/write, and a huge cluster of them may actually increase data latency.Edited by A Bad Day - 2/10/13 at 6:32am
