20 TB SAS drive for Dell servers

This 20 TB 3.5 inch internal hard drive uses a 12 Gbps SAS interface and spins at 7.2K RPM. It is built for Dell PowerEdge servers and storage arrays that require high-capacity nearline storage. The 512e format helps compatibility with a wide range of controllers and operating systems.

Sustained throughput for nearline workloads

The 7.2K rotational speed delivers consistent sequential performance for bulk data, backup targets and archive volumes. A 12 Gbps SAS link keeps the pipe full during long write streams without the latency spikes seen on slower interconnects. Firmware is updated to the latest vendor release for stable operation under continuous duty cycles.

Verify controller and bay compatibility

Confirm your PowerEdge model appears in the supported list such as R740, R750, R760 or MD2460 before ordering. The server must provide a 12 Gbps SAS backplane or HBA and a 3.5 inch drive bay with the correct carrier. Systems limited to 6 Gbps SAS or 2.5 inch bays will not support this drive.

Questions sur cet article

How much heat does the 20 TB 7.2 K SAS drive add to a server running continuously?

The Ultrastar DC HC580 is a 3.5-inch nearline drive rated for 7.2 K RPM; its typical operating power falls within the standard range for 20 TB helium-filled SAS disks, so normal server airflow handles the heat.

What controller or backplane must I already have to use the 12 Gbit/s SAS interface?

A SAS HBA, RAID card or server backplane that supports 12 Gbit/s SAS wide ports is required; the drive uses the standard 3.5-inch SAS connector found in compatible Dell PowerEdge systems.

Will the 512e 20 TB drive work in my older Dell PowerEdge R740 that currently runs 4 TB 512n SAS disks?

Yes, the R740 is listed as compatible; the 512e format presents 512-byte logical sectors so the existing RAID controller and OS see the new drive the same way as the older 4 TB units.
