QNAP TR-004 4-Bay USB 3.2 Gen 1 RAID Expansion Enclosure, with 4x 8TB NAS HDD

<b>Effective storage expansion with RAID Support</b>The TR-004 is an ideal storage expansion solution for PCs, especially for laptops which lack the ability to install larger, higher-capacity drives. Featuring four 3.5-inch SATA drive bays and supporting RAID configuration, the TR-004 provides the ability to store a vast number of files and data and to ensure protection against potential drive failure.<b>Supports various RAID levels</b>The TR-004 supports a variety of RAID configurations. Depending on your requirements, you can switch between hardware- or software-controlled RAID modes. Move the DIP switches to corresponding positions for your ideal RAID mode: Individual, JBOD, RAID 0, RAID 1/10 or RAID 5. You can also configure the RAID settings from your QNAP NAS, or by using the QNAP External RAID Manager utility on your computer.<b>Individual Mode</b>Treats every disk as separate storage space, allowing you to independently access each one.<b>JBOD Mode</b>All the disks are recognized as a single drive. This allows maximal storage utilization but provides no data protection.<b>RAID 0 Mode</b>Data is split amongst the drives. RAID 0 provides the fastest performance but does not protect data from drive failure.<b>RAID 1/10 Mode</b>Half of the total storage capacity is used to store data, and the other half keeps a copy of this data. This provides high data protection at the cost of only being able to use half the installed storage space.<b>RAID 5 Mode</b>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.<b>Software Ctrl Mode</b>Use this mode to control the RAID configuration from your NAS or computer.<b>Flexible storage configuration and management</b>Compared with other RAID enclosures, the TR-004 provides software-controlled configurations for greater management flexibility. Users can configure RAID and monitor disk health using Storage & Snapshots Manager on a QNAP NAS, or by using the QNAP External RAID Manager utility on their 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.<b>Versatile usage scenarios to meet storage expansion needs</b>The TR-004 meets many storage expansion requirements for home and work use, including:<b>Expand the capacity of your NAS</b>The TR-004 provides an alternative method for users to expand their NAS storage capacity.
