Through the USB 3.0 Super-Speed transmission interface, the GR2660-B3 accommodates two 2.5" hard drives or solid state drives. With the built-in RAID mode switch, you can easily switch between RAID 1 (mirroring), RAID 0 (striping) or JBOD configurations, giving you both security and fast transmission. GR2660-B3 Screw-free hard drive installation, requires no fuss and no tools. Everything is that simple by installing the drive, choose RAID mode, format the disk, and you're ready to go!

Over 60% faster than the first generation, internal structure of GR2660-B3, you'll find a SATA III (6 Gbps) chipset and transform to a USB 3.0 (5G) interface which is the most convenient interface. That means you'll get transmission speeds over 60% faster than the previous generation R2420.
