Dell Constellation ES.3 1TB SAS drive
The Dell Constellation ES.3 ST1000NM0023 is a 3.5-inch internal hard drive built for servers and workstations that need reliable bulk storage on a SAS backbone. It ships new with an R-series caddy for tool-less installation in compatible Dell bays.
1TB capacity with 128MB cache
One terabyte provides room for operating-system images, databases and archival workloads, while the 128MB buffer absorbs bursty write traffic. The 7200RPM spindle sustains sequential throughput for streaming reads, but random I/O will saturate the mechanical latency ceiling under heavy multi-user loads.
6Gb/s SAS interface ceiling
The 6Gb/s SAS link caps sustained transfer at the bus limit, so the drive cannot exceed that ceiling even during sequential operations. Dual-port SAS topology is not exposed on this model, so multipath redundancy and expander fan-out remain unavailable.

Questions about this item
Will the 3.5" SAS 6Gb/s interface on this ST1000NM0023 work with my existing 3Gb/s SAS backplane?
Yes, the 6Gb/s SAS interface is backward compatible with 3Gb/s SAS controllers and backplanes, so the drive will operate at the lower speed.
How can I verify the 128MB cache and 7200RPM speed are active after installing the drive?
Check the drive identification in your RAID controller BIOS or use a tool like smartctl to confirm the reported rotational speed and cache size match the specifications.
Does the included R Series caddy fit a standard Dell PowerEdge 2.5" drive bay, or do I need a different bracket?
The supplied caddy is designed for 3.5" R Series drive bays in compatible PowerEdge servers; it will not fit a 2.5" bay without an additional adapter.
