How to use
Power off the enclosure if required by the model instructions, open the tool-accessible bays and insert compatible SATA or NVMe SSDs into the drive slots, securing them according to the enclosure's mounting method. Connect the enclosure to a host computer using a USB4-capable port and the provided cable. The host operating system should detect the attached drives; initialize, format, or configure them as needed for your backup, editing, or storage workflow. For hot-swap operations, follow the host OS guidelines for safely removing storage before physically swapping drives to avoid data loss.
