SSDs May Soon be Ready for Implementation into Datacenters

The most obvious and common reason to avoid any SSD solution presently is certainly price. Compared to rotational-magnetic state drives, solid states offer far better performance for most server environments, but prices were keeping them out of the server closet.
However, as datacenters continue to find the need to grow (due to the software-as-a-service movement, cloud server environments, etc) they are finding that the overall power consumption and thermal capabilities of SSDs may be worth the cost.
MySpace recently revamped their server outfit with SSD technology and managed to cut hardware costs by 60 percent simply by using SSDs. It was undoubtedly an expensive move, but what they spent in hardware they’ll make up for in infrastructure savings. The SSD units they used will save them 50 percent on power, and 80 percent in cooling.
Those are hard numbers to argue with. Check out the white paper at the fusionIO site (PDF).

But doesn't a SSD move also reduce capacity? (then again if the servers are old enough the HDD could have similar capacity)

It depends what size drive you're running. If you read the case study, MySpace made the change for their cacheing servers. Basically RAM on hard drives. So performance is everything, not capacity. They needed 12 magnetic drives using RAID to get the I/O that one of the SSDs can provide. I'm sure they have other storage arrays using 1TB or larger drives that provide long term storage for all the data.

and thus why I asked ;)
