The Shuttle PHD2-N is an internal HDD/SSD bracket for Shuttle XS35 series systems. It allows an additional 2.5" SATA hard drive or SSD to be installed inside the chassis, using the position normally reserved for the optical slimline drive.

This makes the bracket a practical accessory when extra internal storage is required for local data, applications, logging or system files. It is suitable for professional Shuttle XS35 installations where internal storage expansion is preferred over external USB storage.

The bracket supports one 2.5" SATA HDD or SSD with a maximum height of 9.5 mm. Shuttle documentation may also reference this accessory as PHD2, PHD2N.
