OWC has announced the expansion of their Data Doubler optical bay drive mounting kit. The kit now works in 2009-era Mac minis and 2009-2010 iMac models. It costs $79.99.

The Data Doubler replaces the “SuperDrives” present in these systems from the factory with a mount which can accommodate a hard disk drive or SSD – a second drive to accompany the internal drive already inside. That way, Mac minis and iMacs can be expanded with additional storage capacity, or through RAID 0 striping, a boost in hard disk drive performance.

OWC says the Mac mini kit is user-installable, but it recommends professional installation for the iMac kit.
