Frequently Asked Questions
What is a RAID enclosure and how does it protect my data?
A RAID enclosure uses multiple drives working together to protect your data. RAID 1 mode mirrors your data across both drives, so if one fails, your data remains safe on the other. RAID 0 combines drives for maximum speed, while JBOD allows independent drive operation. The CRU RTX220-3QR supports all three modes for flexible data protection strategies.
Can I use this external storage enclosure for Mac and Windows?
Yes, the USB 3.0 external storage is compatible with both Mac and Windows systems. Simply connect via USB 3.0 and the drives will be recognized as external storage devices. No special drivers are required for most modern operating systems.
How do I install drives in the TrayFree bays?
The TrayFree design eliminates the need for tools or trays. Simply open the enclosure, slide your 3.5-inch or 2.5-inch drive into the bay, and secure it with the quick-release mechanism. Drives can be installed or removed in seconds without powering down the system.
Is this RAID storage system suitable for backup in a small business?
Absolutely. The two-bay RAID enclosure is purpose-built for SMB and workgroup backup scenarios. Its USB 3.0 connectivity, RAID redundancy, and compact design make it an affordable, reliable solution for protecting critical business data without requiring dedicated IT infrastructure.
