The TR-004 4-Bay USB 3.2 Gen 1 RAID Expansion Enclosure from QNAP is unique in that it allows you to expand the storage capacity of not only your QNAP NAS, but also your host Windows, Mac, or Linux system. Use it in this fashion as a DAS (Direct-attached Storage) and access its content simply by connecting it to your system using its integrated USB 3.2 Gen 1 Type-C port and the included USB Type-C to Type-A cable. The TR-004 features four hot-swappable 3.5" SATA drive bays that support 3.5" and 2.5" hard drives, as well as 2.5" solid-state drives. The drive bays can be configured hardware- or software-controlled RAID 0, 1, 5, and 10 modes, each of which offers performance, data redundancy, or a combination of both. For those who do not require a RAID, Individual and JBOD modes are also available. The brings you a reliable and secure storage capacity expansion solution that supports data transfer speeds up to 227 MB/s and keeps cool using a 120mm smart fan.
Individual Mode treats every disk as separate storage, allowing you to independently access each one. In JBOD mode, all disks are recognized as a single drive, which allows maximum storage utilization, but provides no data protection. RAID 0 splits data among the drives and provides the fastest performance, but does not protect data against drive failures. RAID 1/10 uses half the total storage capacity to store data and the other half for 1:1 data redundancy. This provides high data protection at the cost of only being able to use half the installed storage space. RAID 5 requires at least three drives to use and parity information is distributed among the drives, providing optimized storage capacity and protection against one disk failing. All of these RAID modes are hardware controlled, but there is also a Software Control mode to configure the RAID from your NAS or computer.
Use Storage & Snapshots Manager to configure the TR-004 as a storage expansion unit for your QNAP NAS. In addition to RAID configuration, the NAS expansion storage mode supports various NAS functions, including storage pools and snapshots. By choosing external storage mode, you can use the TR-004 as a DAS.
The QNAP External RAID Manager is a utility for Windows and Mac users to set up, monitor, and view the status of the TR-004. Users can easily configure RAID groups on the TR-004 and quickly obtain the status of RAID performance and health at a glance.
Note: When connecting the TR-004 to a NAS, users can choose to use either the NAS expansion storage mode or the external storage mode.
Note: To access devices that use the exFAT file system, users must purchase a separate exFAT driver license.
