Recording technology for the WD4005FZBX is held, not stated: the document we cited (WD Black performance desktop hard drive product page) no longer resolves and we found no archived copy. The nearest model with a sourced answer is the WD44PURZ (CMR).
We hold no vendor document that defines the segments of WD4005FZBX, so we do not decode it.
Nearest model with a sourced answer: WD44PURZ (WD Purple 4TB, CMR). Listed for comparison only - two part numbers can use different recording methods, so its answer is not WD4005FZBX's.

Without a manufacturer document we can cite, we cannot tell you whether this drive shingles its tracks, and that is the field that decides whether it belongs in an array. Treat it as unverified rather than as probably fine: if the drive is going into a NAS or anything that rebuilds, buy a model whose recording technology is sourced. If it is a single drive holding replaceable data, the recording technology is largely academic and this is a reasonable purchase either way.

A dash means we have not found a manufacturer document stating that field for this exact model. We leave it blank rather than filling it from a retailer listing.
We checked WD Black performance desktop hard drive product page and it does not state this part number's recording technology, so we do not state one. The nearest model with a sourced answer is the WD44PURZ, which is CMR.
The recording technology is unsourced, so we cannot clear it for arrays either way. What the spec table does say: no stated workload rating and a 5-year warranty. For an array, prefer a 4TB drive whose recording technology is sourced, such as the WD44PURZ (CMR).
