The HOT SWAP SATA RAID-1 KIT is a high-performance and extremely flexible solution for RAID 1 disk mirroring. With a cost effective SATA approach, the ACS-75170 mirrors data to the other disk drive simultaneously, and delivers optimized performance. If one drive fails, data is secured by the other drive and alarm sounds to alert you.
 

Featuring intelligent online recovery, ACS-75170 let you hot swap a failed drive and it automatically rebuilds the data to the new drive without any system down time. The 75170 RAID box features a user-friendly rack design that lets you easily install a backup drive, or replace a drive that fails. Each hard drive carrier supports a one-inch high 3.5 inch for factor disk drive. Additional data security is provided by a key-locking system, that prevents unauthorized access to each disk drive.
