The SAT3520U3SR USB 3.0 RAID Enclosure turns two 3.5" SATA (SATA I, SATA II, SATA III) hard drives into an external RAID array through a USB 3.0 connection. Large capacity drives (tested with up to 4TB per bay) can be used to greatly enhance your computer storage/backup capabilities.
Whether it's greater capacity or data redundancy you're looking for, this USB 3.0 dual drive enclosure is the solution, with built-in support for multiple RAID modes (RAID 0, 1, JBOD) which enables the enclosure to fit the role you need. The drive enclosure also supports non-RAID operation, so both drives can be used independant.
Compliant with the SuperSpeed USB 3.0 specification, which can provide up to 5 Gbps of data bandwidth (10x more than USB 2.0), the SAT3520U3SR RAID enclosure makes it easier and faster to transfer or stream large amounts of data. Although the dual drive enclosure will perform at peak speeds when connected to a USB 3.0 host computer, it is also more than suitable for use with older systems, as it is backward compatible with USB 2.0 connections.
- Dual bay USB 3.0 enclosure supports the latest USB standard for up to 5 Gbps of data bandwidth for faster data transfers than USB 2.0.
- Built-in support for multiple RAID modes suit most personal/business needs for easier setup.
- USB 3.0 RAID enclosure with a 50mm cooling fan keeps the hard drives cool over extended periods of activity, for optimized performance.
