DailyTech reports eBay switched 100TB of HDD-based storage to SSD and saw impressive gains in performance and power efficiency:
EBay ended up replacing 100TB of HDD-based storage in a single year with the SSD-based storage and saw some impressive gains and improvements from the swap. The reduction in storage rack space between the old solution and the new SSD solution was 50%. The reduction on power use was 78% and in a large data center, the reduction in power use can mean huge savings on electric bills.

While a reduction in the number of storage racks and a big reduction in power consumption are both great things, the performance is what eBay was after. The time to roll out a new VM is now five minutes compared to 45 minutes on the old system according to eBay.
