Dell 400-AJPI 1.2TB SAS drive

The Dell 400-AJPI is a 1.2TB internal hard drive with a SAS 12Gb/s interface and a 10000 RPM spindle speed. Its 2.5 inch form factor fits compatible drive bays in Dell servers and storage arrays. The drive is supplied new and adds high-speed capacity to supported systems.

Suits SAS-equipped servers needing 10K performance

This drive suits administrators expanding storage in systems that accept 2.5 inch SAS drives running at 12Gb/s. It is not for platforms that lack a SAS backplane or controller, or for builds requiring a 3.5 inch form factor. Buyers needing larger capacities or different interface protocols should consider other options.

SAS 12Gb/s interface decides compatibility

The single specification that determines fit is the SAS 12Gb/s interface. The drive must connect to a compatible SAS controller or backplane that supports 12Gb/s signalling. Without that connection the drive cannot operate, regardless of capacity or spindle speed.

Questions about this item

Will the 2.5" form factor fit my server's drive bay?

The drive uses a standard 2.5" form factor compatible with 2.5" SAS hot-swap bays or fixed cages.

What is the correct way to connect the SAS 12Gb/s interface during installation?

Attach the SAS data and power connectors firmly until they click; the common error is leaving the data cable partially seated, which causes link negotiation to fall back to 6 Gb/s.

How often should I plan to replace a 10000 RPM SAS drive like this 1.2TB model?

Enterprise 10K RPM drives are typically rated for five years of continuous operation; monitor SMART reallocated-sector counts and replace the unit once the count rises steadily.
