CRU RTX220-3QR Portable two-drive USB 3.0 RAID storage enclosure with TrayFree™ bays


The RTX220-3QR hard drive enclosure and its two disk drives brings ease of use and flexibility to portable RAID storage. It is available without any drives (supply your own), or with 4TB or 8TB pre-configured for Mac or Windows.

The RTX220-3QR lets you choose between combining its two drives into a RAID 0 (stripe) for the utmost in speed or creating two copies of your data simultaneously with a RAID 1 (mirror) configuration. The rugged construction and deep-scoop handle is perfect when you need to bring TBs of data with you, whether on a photo shoot or in the back of a surveillance vehicle.

With four different connection options (USB 3.0/2.0, FireWire 800, and eSATA), the RTX220-3QR can transfer data at speeds of 150+ MB/s (depending on drives and connection type).

TrayFree bays make adding or swapping drives effortless. It’s as easy as opening the door, sliding the drive in, and closing the door. No screws, no trays. It just works.

Additional features:

  • Support for any capacity 3.5” SATA hard drive
  • 3-year limited warranty
