Hands-on with the OWC Mercury Elite-AL Pro Dual mini SSD

When I think of RAID, I usually envision a large box full of whirring drives installed in a rack, not a quiet little box that I can connect to a MacBook. Thanks to Other World Computing, the way I visualize RAID will have to change.

For those of you who might be unfamiliar with the term RAID, it stands for Redundant Array of Inexpensive Drives. In this review, I'll talk about RAID 0, which stores information on two or more drives that are linked together. RAID 0 is usually a much faster storage solution than just a single hard drive. RAID 1, on the other hand, just mirrors data written to one of the drives onto a second drive. It's great for creating a fairly bulletproof storage solution.

The Mercury Elite-AL Pro Dual mini (referred to as the Pro Dual mini from here on out) is a new product from OWC that is a fast, redundant quad-interface (USB/FW400/FW800/eSATA) dual SSD array (that's two solid state hard drives networked up together). When the Pro Dual mini is connected to a Mac through FireWire, no external AC adapter is required, making this drive an excellent portable RAID solution. The USB interface requires an optional AC adapter, adding both cost ($10) and weight to the equation. For use with eSATA, either a FW800 to 12-volt power cable (included) or the AC adapter is required to power the drive.

Physically, the Pro Dual mini fits two 2.5" SATA SSD drives into a tough 5.6 x 6.1 x 1.1 inch aluminum enclosure. The drives are OWC's Mercury Extreme Pro RE SSDs, which are rated at up to 263.6 MB/sec write speeds and 271.5 MB/sec reads. What would you use a small, fast RAID array for? A/V, digital photography, professional music or graphics are the use cases that come to mind.
