Therefore SSDs are not kept busy seeking to new drive locations and, in turn, introducing latency. As great as this sounds, SSDs are still more expensive than HDDs. HDD prices have settled to around $0.03/GB; SSD prices vary but sit at around $0.13-$0.15/GB. At scale, that price gap makes a world of difference.
