"Comparing the Constellation ES.3 to a pair of consumer mechanical drives shows the performance advantage of this drive in just about every test. RAID 0 performance scaled nicely, driving throughput of the Constellation drives to a level on par with some earlier solid state drives. Speed and capacity are what the Constellation drives bring to the table. Surely the 128MB of onboard cache helps the performance along with the 7200RPM spindle speed. As an enterprise class drive it is meant to spend its lifespan of 1.4 million hours dutifully answering data calls.
