This is the right R440 variant when 8 bays comfortably cover the storage tier, when 135 W or higher CPUs are part of the spec (which cap drive count at 8 anyway per Dell's thermal restriction matrix), or when fleet standardization on uniform 8-bay configs reduces operational complexity.\u003c\/p\u003e\u003cp\u003eThis is a companion to the canonical \u003ca href=\"\/products\/dell-poweredge-r440-4-bay-3-5-chassis\"\u003eR440 4-Bay 3.5\"\u003c\/a\u003e.

For most R440 deployments this is sufficient; the difference between 76.8 TB on the 10-Bay variant and 61.4 TB on the 8-Bay variant is rarely the binding storage constraint when SSD is the drive class.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e135 W+ CPU consideration is the load-bearing reason this chassis exists alongside the 10-Bay:\u003c\/strong\u003e Per Dell's R440 thermal restriction matrix, drive count caps at 8 on systems with a 135 W processor. Named CPUs that cross this boundary include Gold 6132, Gold 6140, Gold 6142, Gold 6240, Gold 6242, Gold 6248, and Gold 6252. If your spec is one of those, the 10-Bay chassis is constrained to 8 populated bays anyway - the 8-Bay configuration is the cleaner architectural answer because it matches bay count to thermal envelope at order time rather than running a 10-Bay chassis with 2 empty bays.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDrive options we recommend:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSAS SSD Read-Intensive:\u003c\/strong\u003e 960 GB, 1.92 TB, 3.84 TB.

There is no architectural disadvantage vs the 10-Bay other than 2 fewer bays and the absence of the optional expander backplane. For many R440 deployments, 8 bays is genuinely sufficient and the price savings flow directly to total cost of fleet rollout.
