On paper, yes. But it really depends on the workload. At the end of the day, if you're architecting appropriately it's apple's and oranges. SATA/NL-SAS drives excel at large streaming workloads - think video rendering, storing large ISOs, video surveillance, database dumps.

SSDs are highly transactional workloads like databases or most back-end systems for applications or virtual machines.

You RARELY see the two used for the same type of workload unless someone has money to burn and wants to standardize on SSD and doesn't care about cost. SATA/NL-SAS being used for a workload that should be on SSD generally results in someone getting fired and the original system being forklift replaced.
