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. In data centers capacity is king, but operating expenses do drive the bottom line. To that end Seagate´s Constellation ES.3 line have improved power management capabilities that allow it to consume only 11.27 watts under load using its proprietary PowerChoice™ technology to reduce power consumption by up to 54%. The lower power consumption and associated thermals allow a density of up to 152TB per square foot. The Constellation ES.3 drives are available either in a SAS or SATA 6Gbps interface to meet the storage requirements. There are a few key differences in the feature set when comparing the SAS and SATA interface drives. The SAS equipped drives support Self-Encryption with FIPS 140-2 and Seagate Instant Secure Erase whereas the SATA version does not. As you might expect an enterprise class drive such as Seagate´s Constellation ES.3 series is going to come with a higher price tag. That price tag reflects the enterprise class reliability of the drive that comes with a five-year warranty period. The SATA version of the Constellation ES.3 4TG drive is currently priced at $389 while the SAS drive is priced slightly higher at $426. If you do not need the enterprise class feature set or long term reliability that comes with it, Seagate does offer a consumer 4TB drive for about half the price at $189. It does, however, also have half the cache and lower MTBF coupled with a three year reduction in the warranty period to two years. As a consumer drive the Constellation ES.3 4TB would be a pricey option, but it backs that price up with enterprise class reliability and excellent disk drive performance. If you need massive amounts of storage the Seagate Constellation ES.3 4TB drive is up to the task.
