Enterprise nearline drive

This Seagate Constellation ES model is a 500GB SAS hard drive built for 24×7 operation in enterprise storage arrays. It spins at 7200 RPM with a 64MB cache and includes self-encrypting drive technology. The 3.5-inch form factor fits standard server bays and it ships as a bare drive without accessories.

Suited for array rebuilds and cold tiers

The drive serves administrators who need a replacement SAS disk for existing nearline enclosures or a cost-effective tier for infrequently accessed data. Buyers who require larger capacities or faster interfaces for active workloads should evaluate other options. The bare-drive packaging also means no cables or mounting hardware are included in the box.

SAS 6Gb/s interface

The single specification that determines compatibility is the 6Gb/s SAS interface. Your backplane, HBA or RAID controller must support this exact protocol and speed for the drive to function. A system equipped only with different interfaces will not recognise the device.

أسئلة حول هذا المنتج

How often should the 64MB cache drive be replaced in a 24×7 server?

The Constellation ES series is designed for continuous 24×7 operation with a 5-year limited warranty; replacement timing depends on workload and SMART monitoring.

What throughput limit appears first when the SAS 6Gb/s interface runs sustained writes?

The 7200 RPM mechanical speed and 64MB cache determine the sustained write ceiling before the 6Gb/s SAS link saturates.

How much heat and noise does the 3.5" 7200 RPM drive produce during all-day operation?

Enterprise nearline 7200 RPM drives run warmer and louder than desktop models; ensure adequate chassis airflow for 24×7 use.
