Server-Ready 4TB SAS Drive Kit

The Epoch YXG4K kit supplies a 4TB 3.5" hard drive spinning at 7200 RPM with a SAS 12Gb/s interface. It is built for Dell PowerEdge 14 and 15 Generation rack and tower servers as well as Dell Tower 15 Generation systems. The drive arrives in retail or OEM packaging and is tested for full OEM compatibility.

Suited for Enterprise Storage Arrays

This drive fits administrators expanding capacity in compatible Dell PowerEdge R240 through R940xa servers and T150 through T550 towers. It is not a fit for systems that lack a SAS 12Gb/s backplane or controller, nor for laptops and small-form-factor desktops that cannot accommodate a 3.5" form factor.

SAS 12Gb/s Interface Decides Compatibility

The single specification that determines fit is the SAS 12Gb/s interface. The server or storage enclosure must provide a matching SAS 12Gb/s connection and a 3.5" drive bay; without that interface the drive cannot communicate with the system.

Questions about this item

Will the SAS 12Gb/s interface require any firmware updates or controller changes over time?

The drive uses a standard SAS 12Gb/s interface that works with existing controllers; no firmware updates are mandated by the drive itself.

What is the first limit reached during sustained 7200 RPM operation in a server chassis?

Sustained throughput is capped by the SAS 12Gb/s link and the mechanical 7200 RPM platters before thermal limits appear.

How much noise and heat does the 3.5" 7200 RPM drive produce when running all day in a PowerEdge rack?

The 3.5" 7200 RPM mechanism generates typical enterprise drive acoustics and heat; ensure standard server airflow for continuous operation.
