Dell 4TB SAS 12Gb/s 3.5" Drive

This Dell 400-ALNY internal hard drive provides 4TB of storage in a standard 3.5-inch form factor. It operates at 7200 RPM with a SAS 12Gb/s interface for enterprise connectivity. The drive is supplied new and intended for desktop or server installations requiring nearline performance.

Suits Arrays Needing 12Gb/s SAS

This drive suits administrators expanding storage arrays that accept 3.5-inch SAS devices at 12Gb/s. It is not for systems limited to slower SAS speeds or smaller form factors. Buyers whose controllers only support 6Gb/s SAS should verify backward compatibility before purchase.

Interface Speed Is 12Gb/s SAS

The single specification that decides fit is the SAS 12Gb/s interface. Your host bus adapter or RAID controller must explicitly support 12Gb/s SAS to utilise the drive at its rated throughput. Without that interface support the drive will not function as intended.

Questions about this item

What throughput does the SAS 12Gb/s interface actually deliver?

The SAS 12Gb/s interface supports up to 12 Gbit/s per lane; sustained throughput depends on the 7200 RPM platters and the host controller.

Will this 3.5" drive fit my standard desktop bay?

Yes, the 3.5" form factor matches standard desktop drive bays and uses the industry-standard SAS connector layout.

How do I install this drive in a Dell server and what step is often missed?

Slide the drive into the hot-plug carrier until it clicks, then ensure the carrier handle locks fully; the SAS backplane handles power and data automatically.
