The TR-004 RAID expansion box with a USB 3.0 interface allows you to expand the storage capacity of a QNAP NAS server or a computer. The TR-004 can also be used as a directly attached external storage (DAS) that only needs to be connected to a device’s USB port to access its drives. The TR-004 chassis includes four 3.5-inch bays for SATA drives and supports multiple RAID configuration options. Combined with a USB 3.0 Type-C connection, it provides a reliable and secure solution for expanding storage capacity.
