Yes, this mobile rack does support hot-swapping of SATA drives. To use this feature, it is required that the SATA port is set to Advanced Host Controller Interface (AHCI) mode and hot-swapping is enabled. On most motherboards, this is performed within the Basic Input/Output System (BIOS) or the Unified Extensible Firmware Interface (UEFI). If you are using a SATA controller card, consult the motherboard manufacturer's technical documentation for the correct steps to accomplish this.
