DELL ST500NM0011 500GB 7200RPM 64MB 3.5" SATA internal hard drive with tray

Dell Constellation ES 500 GB SATA drive

The Dell Constellation ES ST500NM0011 is a 3.5 inch internal hard drive with a 500 GB capacity. It spins at 7200 RPM and connects through a SATA 6 Gb/s interface with a 64 MB cache. The unit ships with an R Series tray for direct mounting in compatible Dell server or workstation bays.

Suited for storage expansion in Dell R Series

This drive fits administrators adding nearline capacity to Dell PowerEdge or Precision platforms that accept 3.5 inch SATA drives with the supplied caddy. It is not for builders who need a second drive bay but lack the proprietary tray, nor for users who require higher throughput than a single mechanical spindle can deliver.

Sustained workload behaviour

Under continuous read or write activity the 7200 RPM platters and 64 MB buffer maintain steady transfer rates within the SATA 6 Gb/s link limit. The enterprise-class Constellation ES firmware manages thermal output during extended operations, so performance remains consistent without the sharp throttling seen in consumer desktop drives under similar loads.
