Dell 400-AUUY 1.2TB SAS drive

The Dell 400-AUUY is a 1.2TB internal hard drive built for 2.5-inch bays and SAS 12Gb/s interfaces. It spins at 10000 RPM and ships as a bare drive with hot-swap capability. The 512n sector format supports direct integration into compatible arrays.

Suits servers needing hot-plug 10K SAS storage

This drive fits administrators who need 1.2TB of 10000 RPM capacity on a 12Gb/s SAS link with hot-plug support. Buyers whose systems only accept 3.5-inch carriers or lack a SAS backplane cannot use this drive in its supplied form. Environments requiring larger capacities or different interfaces should consider other options.

12Gb/s SAS interface decides compatibility

The single specification that determines fit is the 12Gb/s SAS interface. The drive communicates exclusively over this protocol, so the host controller and backplane must support SAS 12Gb/s operation. Without a matching SAS connection the drive will not function.

Questions about this item

Does this 2.5" SAS drive need a 3.5" hybrid carrier to fit in my server bay?

Yes, the drive ships with a 3.5" hybrid carrier so the 2.5" unit mounts directly in a standard 3.5" hot-swap bay.

What is the correct way to hot-plug this 12Gb/s SAS drive without causing detection errors?

Insert the carrier firmly until the latch clicks while the backplane is powered; the SAS connector seats last, so do not force the drive past the first resistance point.

When should I expect to replace the 1.2TB 10000 RPM mechanism in a RAID array?

Monitor SMART reallocated-sector counts and schedule a swap once the counter begins to climb, typically after several years of continuous operation.
