Dell 342-5572 4TB SAS drive

The Dell 342-5572 is a 4TB 3.5 inch internal hard drive using a SAS interface at 7.2K RPM. It ships as a bare drive with a hot-swap tray included for direct installation. The unit is designed for server workloads and arrives in new condition.

Verify SAS backplane and controller

Check that your chassis provides 3.5 inch hot-swap bays wired for SAS at 12Gb/s average latency. Ensure the RAID or HBA controller supports the drive’s 6Gb/s link speed and that firmware is current. Confirm the operating system includes the appropriate SAS drivers before deployment.

Thermals noise and power in normal use

In typical server operation the 7200 RPM spindle produces audible seek noise and measurable vibration. The drive draws steady power during sequential workloads and runs warmer under sustained writes. Adequate airflow across the 3.5 inch form factor is required to maintain reliable temperatures.

Questions about this item

Does the 342-5572 ship with a hot-swap tray or is it a bare drive?

The drive includes a hot-swap tray for direct installation in compatible PowerEdge or PowerVault bays; no separate caddy is required.

Should I choose the 4 TB 7.2K SAS model or a different capacity for my server?

Select this 4 TB 7200 RPM SAS drive when you need high-capacity nearline storage with 6 Gb/s throughput for Dell servers; other capacities change the raw space but keep the same interface and form factor.

What does the 12 Gb/s average latency figure mean once the drive is in a RAID array?

The 12 Gb/s rating reflects the SAS interface burst speed; sustained throughput in a RAID array will be limited by the 7200 RPM rotational speed and the 6 Gb/s link negotiation.
