SKU CH-9Z69-VBEZD MPN ST33000650NS

A 3 TB, 7200 RPM Sata hard drive with 64 MB cache in a 3.5 inch form factor

  • 3 TB capacity stores large data sets
  • 7200 RPM rotation speed delivers quick data access
  • 64 MB cache buffers bursts for smoother throughput
  • SATA 6.0 Gb/s interface enables fast host transfers
  • Constellation ES.2 series built for enterprise reliability

Capacity and interface

The Seagate Constellation ES.2 ST33000650NS is a 3TB internal hard drive built for 3.5-inch bays with a SATA 6.0Gb/s connection. It targets system integrators and server operators who need bulk storage in a standard enterprise form factor.

Upgrade path and fit

The drive replaces earlier Constellation ES models or similar 7200RPM enterprise SATA disks when capacity or cache must increase. The jump is worth it when workloads demand the larger 3TB platters and 64MB buffer without changing the 3.5-inch mounting or SATA cabling.

Sustained workload behaviour

Under continuous operation the 7200RPM spindle and 64MB cache deliver steady throughput for sequential archives, backup targets and video surveillance arrays. Firmware RA05 is tuned for 24/7 duty cycles rather than burst desktop use, so performance remains consistent across long write sessions.

  • 7200 RPM rotation speed delivers quick data access
