Enterprise bulk storage

This refurbished Seagate Constellation ES.2 drive delivers 3TB of capacity over a SAS 6Gb/s interface, spinning at 7200 RPM with 64MB cache. It is built for 24x7 operation in enterprise storage arrays and servers that demand sustained throughput and end-to-end data integrity.

SAS backplane integration

The 3.5-inch form factor fits standard enterprise drive bays and hot-swap trays, requiring a SAS host bus adapter or RAID controller with 6Gb/s links. Dual-processor firmware and enhanced rotational-vibration tolerance keep performance consistent when many drives share a chassis, while PowerChoice technology reduces idle power draw.

Sustained workload behaviour

Average seek time is 8.5ms and average write time is 9.5ms, with 4.16ms average latency under continuous load. End-to-end SAS error correction and optional AES-256 self-encryption protect data integrity during long-running jobs, making the drive suited for high-capacity bulk storage rather than low-latency transactional workloads.

Questions about this item

Will the 7200 RPM spindle speed cause the drive to hit thermal limits during 24×7 operation?

The Constellation ES.2 is engineered for 24×7 reliability with improved power and cooling efficiencies plus low power consumption and enhanced PowerChoice technology to manage heat under sustained enterprise workloads.

How much acoustic noise and power draw should I expect when this 3.5" SAS drive runs continuously?

Enhanced PowerChoice technology and improved power and cooling efficiencies keep both noise and power draw low during all-day operation, while best-in-class rotational vibration tolerance maintains consistent performance.

Does my server need a SAS 6Gb/s backplane or HBA to use this ST33000650SS-RF drive?

Yes, the drive uses a SAS 6Gb/s interface and requires a compatible SAS backplane, HBA or RAID controller with a 3.5" drive bay that accepts the 26.10 mm height form factor.
