WD_BLACK SN850X 4TB

Cat. no. storage-wd-black-sn850x-4tb

Curator note

The large-library pick: 4 TB keeps several big quantised models and their variants on disk at once, so switching models doesn't mean re-downloading. Gen4 speed is plenty for a drive whose job is loading a model once per session. Sandisk now sells it as the SANDISK Optimus GX PRO 850X, so listings may carry either name.
