Mobile Rack II

The Addonics Mobile Rack II is a removable drive kit designed specially to turn any Serial ATA hard drive into a hot swap removable hard drive. Constructed with Aluminum for use in harsh and rough handling environment, the enclosure provides sturdy hard drive protection and efficient heat dissipation for the high RPM Serial ATA hard drive.

Turn SATA hard drive into SCSI
By attaching an optional SATA - SCSI converter onto the back of the drive cradle, you can instantly connect any SATA hard drive to a SCSI controller. You can now replace the expensive SCSI hard drive with a low cost, high performance and high capacity SATA hard drive. Since the SATA hard drive can easily be removed from the drive cradle, the same drive can be interchanged with other drive cradles connected in a SATA system.

You can install any hard drive in less than a minute, simply pull out the drive enclosure and follow the procedure below:

To build a hot swap removable Serial ATA hard drive system, install the drive cradle into a 5 1/4" drive bay as shown in the instructions below. You can now use the drive enclosure with the Serial ATA hard drive like a drive cartridge by sliding in and out of the drive cradle, without restarting* your computer. For using the same removable drive system as an external solution, please visit the Saphhire Mobile Rack II web page.

* Drive access signal is from Serial ATA controller. The primary drive (usually the drive C) cannot be removed from the system.
(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.
