Positioning: workstation‑tier mass‑capacity drive—built to maximize reliable terabytes per bay rather than SSD‑like speed. It’s a solid fit as a large desktop game library and, more typically, for NAS/server mass storage where SATA compatibility matters. Notable: FastFormat lets you switch between 512e and 4Kn to match host requirements. ([seagate.com](https://www.seagate.com/www-content/datasheets/pdfs/exos-x16-DS2011-1-1904US-en_SG.pdf))
