A: This model is 4Kn (4096-byte native) Advanced Format.

Q: Is a drive tray/caddy included?
A: In many deployments a UCS carrier is required; inclusion varies by listing. Confirm whether a caddy is included before purchase.

A: When installed in a compatible hot-swap SAS bay, yes; behavior depends on the server/controller.
