All EzRaid-DD3 products are designed for use with IDE drives and are based on Data Protection Solutions by Arco’s patented DupliDisk IDE mirror technology. Our products come in a wide variety of sizes and shapes, including both internal and external Raid 1 IDE drive enclosures. Each EzRaid device is designated to ensure that your computer and your business stay up and running even if your hard drive fails.

How it Works

EzRaid dual caddy units include two removable hot swap drive caddies that connect to the computer via a single IDE cable. All EzRaid-DD3 Raid 1 controllers and enclosures utilizes only one IDE controller on the motherboard. Once the EzRaid device is installed, all data saves are sent to both drives simultaneously so the drives remain identical. If one of the drive fails, an alarm sounds and the remaining drives seamlessly takes over all operations keeping the system up and running.

All EzRaid Hard Drive mirroring products provide an audible failure alarm and optional remote monitoring capability. Some units provide front panel status information
