Documented selection limits

Match the exact host interface, peripheral/device protocol, connector, firmware, OS/driver and power requirements before ordering. Published maximum rates are interface limits, not guaranteed application throughput. No universal device or current/future OS compatibility is implied. Storage drive(s) are not included unless this exact SKU explicitly says so. Match 2.5/3.5 inch dimensions or M.2 key/length and SATA versus PCIe/NVMe protocol. USB-C connector shape does not guarantee Thunderbolt or USB4 compatibility. Check supplied adapter and host power requirements; UASP needs host/OS support.
