4-Bay SATA Hard Drive Power Switch Selector Module, HDD/SSD Intelligent Power Manager for 2.5"/3.5" Drives, Full-Profile PCI Bracket Included

This SATA hard drive power switch module is a practical multi-disk management hardware designed for users with multiple storage drives. It can independently control the power on and off of four SATA hard drives or SSDs, supporting both 2.5-inch small SSDs and 3.5-inch large-capacity mechanical HDDs.

By manually cutting power to unused hard drives, it effectively lowers overall chassis power draw, lessens heat generation and mechanical wear of idle disks, extending the service life of storage hardware, especially suitable for multi-disk NAS, data backup workstations and surveillance storage hosts that do not need all drives running 24/7.

The whole unit adopts a full-height PCI metal baffle design, which can be fixed to any idle PCI slot on the chassis. All control switches are exposed outside the case, allowing users to quickly switch the power status of each hard drive without opening the chassis.

Built-in stable current protection circuit to avoid short-circuit damage to hard drives caused by frequent power switching. No extra software or driver installation required, plug-and-play for all mainstream Windows and Linux systems. It is an economical auxiliary management accessory for DIY multi-disk storage arrays, personal NAS, video editing workstations and archive data storage equipment.
