- Dual fixed hard drive bays
- Supported RAID modes: 0, 1, JBOD
- SuperSpeed USB 3.0 compliant host interface with support for up to 5Gbps of bandwidth
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.
With a built-in cooling fan the SAT3520U3SR can help extend the life of your hard drives and is backed by a StarTech.com 2-year warranty, and free lifetime technical support.
Applications
- Scenarios requiring easy storage transferability between different computer systems and large volume external storage for backups/archiving
- Video editing or photography professional/enthusiasts working with very large file sizes
The StarTech.com Advantage
- 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

Troubleshooting
When you troubleshoot issues with a hard drive enclosure, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
- Cables
- Hard drives
- Hard drive enclosure
To test your setup components, try the following:
- Use the cables, hard drives, and hard drive enclosure in another setup to see if the problem is with the components or the setup.
- Use a different cable, hard drive, and hard drive enclosure in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test the hard drive and hard drive enclosure, it is recommended that you do the following:
- To check Disk Management, press the Windows key + R, type diskmgmt.msc, and press Enter. Check to see if your hard drive is listed.
- If the hard drive is listed with unallocated space, the hard drive needs to be reformatted. Right-click unallocated and click New Simple Volume. Follow the on-screen instructions to complete the reformatting.
Note: Formatting a hard drive erases all of the data on it. Make sure that you back up all of your data before you reformat the hard drive.
- If the hard drive is listed as healthy but does not have a drive letter, for example, C:, right-click healthy and click Change Drive Letter and Paths. Click Add, assign a drive letter, and click OK.
Note: A formatted hard drive will not show up in Computer or My Computer until it has a drive letter assigned to it.
