X1008 PCIe to 2 ports HDD expansion board, designed to provide a mass-capacity storage and high-speed storage solution for your 5. This board facilitates the simultaneous connection of a 3.5-inch HDD and a 2.5-inch HDD/SSD, unleashing the full potential of your storage capabilities, with 3.0 interface speeds reaching up to 5Gbps. With support for 12V input via a standard DC jack and equipped with high-efficiency DC/DC step-down converters, the X1008 efficiently powers both your Raspberry Pi5 and HDDs from a single power source, simplifying your setup. The X1008 serves as the perfect storage solution for establishing a home media center or constructing a network-attached storage (NAS) system. It empowers you to store and stream your personal collection of videos, music, and digital photos within the confines of your home or remotely from anywhere around the globe. Important Notes: The X1008 is designed for data storage purposes and does not currently support booting from HDD/SSD with the existing firmware. Don' the X1008 and the Raspberry Pi5 at the same time. Older drives with less efficient flash media may not perform as well as newer drives. New HDDs/SSDs are not partitioned and need to be both partitioned and formatted when first connected to the before they be accessed in the Explorer. Compatible With for 5B. Supports the connection of a 3.5-inch HDD and a 2.5-inch HDD/SSD to your 5 simultaneously Compliant with the Serial 3.0 specification, with backward compatibility to 2.0 and 1.0.
