Snap-In Disk Array

The Snap-In Disk Array is the latest Addonics removable drive system that enable installing as many as five 3.5" hard drives into three 5.25" drive bays on any Desktop PC, Tower or 4U Rack mount system. The hard drive can be added into the Snap-In Disk Array by simply sliding the hard drive into one of the drives slots and closing the drive door, just like using a VHS cassette. To remove the hard drive, simply open the drive door and the hard drive will automatically be ejected.

The Snap-In Disk Array also increases the number of hard drives that can be installed into systems or storage chassis such as the Addonics family of Storage Towers. Together, with Addonics Port Multipliers, you can create a powerful RAID storage with large storage capacity, drive redundancy for reliability and high performance in a compact 3-bay drive enclosure like the Addonics Storage Tower III.

*While the Snap-In Disk Array is capable of fitting into three 5 1/4" drive bay stack on a desktop tower, seating from the metal bracket may cause possible obstruction for ion of the Snap-In Disk Array. (1) Serial ATA hot swap feature works only with controllers basing on Silicon Image chip set from our inhouse testing. Other controllers that are not Silicon Image based may not support hot swap. You may consider adding one of the Addonics Serial ATA host controllers to your systems to ensure the hot swap capability. New controllers from Intel and other suppliers may finally support this feature. Please verify with your controller manufacturer if you need to have hot swap in your application. Hot swap is supported in Windows 2000 and XP only. On other OS, drive can be removed without crashing system. But replacing with a different drive can result in crashing the OS.
