Just posted is my review of the OWC Mercury Elite On-The-Go solid state drive (SSD).
Taking a photography trip to Antarctica or Africa? Or have an important job in the field? A wedding shoot that requires travel?
Why risk things on a fragile hard drive— consider a solid state drive for both internal and external use with a MacBook Pro, and reduce the odds of failure.
Anyone whose work product is valuable should be thinking about a solid state drive for critical jobs when traveling, to reduce the risk of data loss from hard drive failure.
The On-The-Go comes pre-assembled, but I got mine as parts. While assembling it, I dropped the SSD two feet onto a hardwood floor. Would a hard drive have survived? I’m not sure, but dropping a drive is not a “black swan” even for me, that’s the second drive I’ve let slip in 3 months. The previous one (a hard drive) was DOI (dead on impact).
The OWC unit is available in 64GB, 128GB or 256GB capacities. My recommendation for reliability: install an SSD as the internal drive for your MacBook Pro and an external one for backup. If you need more space, then stick to a 500GB 7200 rpm laptop drive.
