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.

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 2-year warranty. For an array, prefer a 3TB drive whose recording technology is sourced, such as the DT02ABA400 (SMR).
