The Diamond Hard Drive Enclosure is probably the most versatile storage solution in the market. It allow any 3.5" IDE hard drive to be used as a drive cartridge and as an external high performance eSATA hard drive. Constructed in heavy gauge aluminum with precision finish for smooth operation, the Diamond drive enclosure is built to last while at the same time providing excellent heat dissipation for the hard drive. The Diamond drive enclosure allows the IDE hard drive to appear as a direct connection to the host in eSATA mode. When used as a drive cartridge, the hard drive can be swapped in and out of your computer without restarting your system. Instead of a slow tape cartridge, you enjoy the fast performance of the IDE hard drive. Once the OS detects the presence of the Diamond Drive enclosure (cartridge), it appears as an additional hard drive to the system.
