Dell 400-AJOS 300GB 10K SAS Drive

This new Dell 400-AJOS is a 2.5-inch internal hard drive with a 300GB capacity and a 10000 RPM spindle speed. It connects via a SAS interface and supports hot-swappable installation. The drive is designed for PC platforms requiring high-speed rotational storage in a small form factor.

Suits servers and arrays needing 10K SAS storage

This drive suits administrators upgrading or repairing Dell systems that accept 2.5-inch SAS drives with hot-swap capability. It fits workloads demanding 10000 RPM performance in a 300GB footprint. Builders whose chassis only accommodate 3.5-inch bays or lack a SAS backplane cannot use this unit.

SAS interface determines compatibility

The single specification that decides fitment is the SAS interface; the host must provide a SAS connection and a 2.5-inch hot-swap bay. Without a compatible SAS controller or backplane, the drive will not function. Verify the system supports this interface before purchase.

Questions about this item

How does the 10000 RPM spindle speed affect real-world responsiveness?

The higher spindle speed lowers average rotational latency, so small random reads and writes complete more quickly than on slower drives.

What does the SAS interface limit in actual use?

The SAS interface determines the maximum host-bus transfer rate and requires a compatible SAS controller or backplane to operate.

Will this 2.5 inch drive fit my server bay without an adapter?

The drive uses the standard 2.5 inch form factor and is hot-swappable, so it slides directly into any 2.5 inch hot-swap tray or bay.
