  • 4 TB capacity stores large server datasets
  • 7200 RPM spindle speed delivers quick data access
  • SAS 6Gb/s interface supports compatible PowerEdge servers
  • 32 MB cache buffers bursts for smoother throughput
  • Includes 3.5" caddy tray for direct server installation

Dell 4TB SAS 6Gb/s drive

This Dell 202V7 drive provides four terabytes of storage on a 3.5 inch SAS interface running at six gigabits per second. It spins at 7200 RPM with a 32 MB buffer and ships with a PowerEdge server caddy. The unit is designed for compatible PowerEdge rack and tower servers only.

Thermals noise and power in normal use

The mechanical spindle and actuator produce typical enterprise hard-drive acoustics and heat during standard read and write activity. Power draw follows the SAS 6Gb/s specification for 3.5 inch 7200 RPM drives. Server chassis airflow is expected to maintain safe operating temperatures.

Sustained load behaviour

Under continuous workloads the drive maintains its rated spindle speed and buffer performance across the full four terabyte capacity. The SAS interface supports consistent throughput for multi-user server applications. The included caddy ensures secure mounting in the listed PowerEdge models during extended operation.

Questions about this item

How do I install the 202V7 drive into a PowerEdge R720 and what step is often missed?

Slide the drive into the supplied 3.5" caddy until the SAS connector seats firmly, then lock the caddy lever; the step often missed is fully engaging the lever so the drive does not lose contact under vibration.

What maintenance or replacement will the WD4001FYYG-18SL3W0 need over its service life?

No scheduled maintenance is required; if SMART attributes report reallocated sectors or the 7200RPM mechanism develops excessive noise, replace the drive and rebuild the array from parity or backup.

What limit appears first when the 4000GB SAS drive runs sustained write workloads?

The 6Gb/s SAS interface and 32MB cache cap sequential throughput, so sustained write speed plateaus at the interface ceiling before the 7200RPM platters become the bottleneck.
