Recording technology for the ST500DM009 is held, not stated: the document we cited (Seagate BarraCuda 3.5in data sheet DS2131) no longer resolves and we found no archived copy. The nearest model with a sourced answer is the ST2000VX015 (SMR).
We hold no vendor document that defines the segments of ST500DM009, so we do not decode it.
Nearest model with a sourced answer: ST2000VX015 (Seagate SkyHawk 2TB, SMR). Listed for comparison only - two part numbers can use different recording methods, so its answer is not ST500DM009'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 Seagate BarraCuda 3.5in data sheet DS2131 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 ST2000VX015, which is SMR.
The recording technology is unsourced, so we cannot clear it for arrays either way. What the spec table does say: a 55TB/year workload rating, which is desktop-class duty and a 2-year warranty. For an array, prefer a 500GB drive whose recording technology is sourced, such as the ST2000VX015 (SMR).
