Dell Constellation ES 1TB SAS drive

The Dell Constellation ES ST31000424SS is a 1000GB 3.5 inch internal hard drive spinning at 7200RPM with a SAS 6Gb/s interface and 16MB cache. It ships new with zero hours and includes an R Series caddy tray for direct installation in compatible Dell bays.

Suited for SAS bays only

This drive fits servers or workstations that accept 3.5 inch SAS drives at 6Gb/s and can use the supplied R Series tray. It is not for systems limited to 2.5 inch bays or those requiring larger capacity or higher cache.

6Gb/s SAS interface is decisive

The single specification that decides fitment is the 3.5 inch SAS 6Gb/s interface; the host must provide a matching SAS backplane or controller and physical space for a 3.5 inch drive with the Dell R Series tray.

Highlights

  • 1 TB capacity stores large datasets
  • 7200 RPM spindle delivers responsive throughput
  • SAS 6Gb/s interface connects to compatible controllers
  • 16 MB cache buffers frequent read and write operations
  • Includes R Series caddy for secure 3.5 inch bay mounting

Questions about this item

What real-world throughput does the 6 Gb/s SAS interface allow for the ST31000424SS?

The 6 Gb/s SAS interface sets a maximum theoretical bandwidth of 6 Gb/s; actual sustained transfer rates will be lower and depend on the drive's mechanical performance.

Which drive bay and mounting hardware does the 3.5" ST31000424SS require?

The drive fits a standard 3.5-inch internal bay and ships with a Dell R Series caddy/tray for tool-less mounting in compatible Dell chassis.

How is the ST31000424SS installed, and what step is often missed?

Slide the drive into the included R Series caddy, secure it with the caddy screws, insert the assembly into a 3.5-inch bay, then attach both the SAS data cable and the 15-pin SAS power connector; the power connector is the step most often forgotten.
