DELL Constellation ES.3 55FX5 ST2000NM0033 2TB 7200RPM 128MB SATA internal hard drive

Dell Constellation ES.3 2TB Server Drive

The Dell Constellation ES.3 ST2000NM0033 is a 3.5 inch internal hard drive built for server and storage arrays. It targets system builders who need reliable bulk capacity in a standard LFF bay.

2TB capacity with 128MB cache

The 2TB capacity handles operating systems, applications and large data sets such as media libraries or backup images. The 128MB buffer smooths burst workloads, while the 7200RPM spindle sustains sequential throughput for streaming tasks. Random I/O heavy databases will hit latency limits before the cache fills.

6Gbps SATA with included R Series caddy

The drive connects through a standard SATA 6Gb/s interface and ships with a Dell R Series caddy for tool-less mounting in compatible chassis. The 3.5 inch form factor fits any LFF bay, and the 2.0 pound weight indicates a sturdy mechanical build suited to continuous operation.
