If you need a solid amount of external storage space, value Thunderbolt, and want something with RAID capabilities, then check out OWC’s Mercury Elite Pro Dual ($430-$950). Coming in capacities ranging from 2TB to 10TB, it’s a smart and fast solution for backup, extra file storage, and anything else you might need an external drive for. It’s also going to bring back some memories of the big old silver Mac Pro—although this one’s black, the aesthetic is otherwise similar, and larger than the Mercury Elite Pro Dual Mini.
Most of the versions of Mercury Elite Pro Dual split their capacity between two 7200RPM hard drives, although there’s an option to get the 4TB edition with a hybrid of HDD and SSD. Each one comes with both Thunderbolt and USB 3.0 cables, ensuring you can connect no matter which Mac you’re using. And they each can handle RAID 0, 1, span, or independent configurations, depending on what you want.
