Well, unlike Shaun, I do work for Other World Computing (https://www.macsales.com) but on a personal level, I’ve been conducting the testing and using our memory personally for the last several years and really wouldn’t associate my name with a product I couldn’t personally endorse.
OWC memory upgrades are available from 16MB up to 32GB for nearly every current and past Apple notebook and desktop computer manufactured during the past twenty years, including Mac Pro Xeon, iMac, PowerMac, Xserve, iBook, and PowerBook computers. By maintaining an active state-of-the-art test lab, OWC can ensure its memory upgrades offer the highest product quality and reliability and backs them with a Lifetime Advance Replacement Warranty and Money Back Guarantee.
Our independent memory benchmarks testing on a wide variety of Mac computers consistently demonstrates having more memory provides higher real-world performance. OWC memory performance gains are even more apparent when using memory intensive applications, such as audio/video, photo, 3D modeling, gaming and other applications, where OWC memory upgrades offer the best performance for the investment.
