4 TB SAS 6Gb/s internal hard drive

This 3.5 inch drive adds four terabytes of storage to a Dell system through a SAS 6Gb/s interface. It spins at 7200 RPM to deliver consistent throughput for bulk data workloads. The unit arrives in retail or OEM packaging depending on supply.

SAS interface and 7200 RPM spindle

The SAS 6Gb/s connection provides a direct high-speed link to compatible controllers without extra adapters. A 7200 RPM spindle reduces latency compared with slower rotating drives. No additional software or mounting hardware is included in the package.

Four terabyte capacity for archival workloads

Four terabytes accommodates large media libraries, backup sets and database files in a single bay. Sequential throughput suits streaming reads and writes, while random IOPS remain limited by mechanical rotation. Buyers needing higher IOPS or greater density should consider solid-state alternatives.

Questions about this item

Does the 400-AUWY drive need any periodic maintenance or scheduled replacement parts?

No scheduled maintenance is required for this sealed 3.5" hard drive; it runs until the mechanism wears out, at which point the whole unit is replaced.

What limit appears first when the SAS 6Gb/s drive runs at 7200 RPM continuously?

The 6 Gb/s SAS interface ceiling is reached before the spindle speed can deliver more throughput during sustained transfers.

How much noise and heat does the 4 TB SAS drive produce during all-day operation?

Typical 7200 RPM 3.5" mechanics generate audible seek noise and measurable warmth, requiring standard case airflow to stay within operating temperature.
