Dell YMX9H 4TB SAS Drive

The Dell YMX9H is a new 4TB 3.5-inch internal hard drive built for nearline storage workloads. It uses a SAS 6Gb/s interface and spins at 7200 RPM to deliver consistent throughput for server and desktop arrays. The drive ships as a bare unit with the original Dell part number YMX9H for direct replacement or expansion.

Ideal for 13G PowerEdge Nearline Storage

This drive fits 13G PowerEdge servers and suits administrators adding bulk capacity to existing SAS backplanes. Buyers who need a different interface protocol or a form factor other than 3.5 inches cannot install this unit in their current chassis. Systems without SAS controller support will require alternative storage solutions.

SAS 6Gb/s Interface Decides Compatibility

The single specification that determines fit is the SAS 6Gb/s interface, which must match the host controller and backplane. A 7200 RPM spindle speed and 4TB capacity support the nearline performance profile. Verify that the target system accepts SAS drives before purchasing.

Questions about this item

How often will the 7200 RPM Nearline SAS drive need replacement in a 13G PowerEdge server?

Nearline drives are rated for continuous operation, but actual replacement timing depends on workload intensity and environmental conditions rather than a fixed schedule.

What limit appears first when the SAS 6Gb/s interface runs at sustained throughput?

The 6Gb/s SAS link sets the maximum data rate, so the interface bandwidth is the first ceiling reached during prolonged sequential transfers.

How much noise and heat does the 3.5 inch 7200 RPM drive produce when running all day?

A 7200 RPM 3.5 inch Nearline drive generates typical mechanical noise and heat for its class; ensure the server chassis airflow matches Dell's thermal design for 13G PowerEdge systems.
