Hi, I am working with incompressible video/audio files and switched to OWC 115GB Mercury Pro for added speed using Adobe Lightroom and Final Cut Express. I am using a MBP 13" 2010(7,1) at 2.4ghz with 4gb RAM, SSD in the Optibay slot, and a 500gb 5400rpm Apple installed drive However, I discovered why the performance boost I expected from these programs never materialized: the SSD chokes when writing incompresible data(such as images/video) down to 70mb/second which is about the same as the 5400rpm 500gb on the Macbook Pro 2010. http://macperformanceguide.com/Reviews-SSD-OWC-Mercury_Extreme-115GB.html I paid $270 and want to find an SSD similarly priced but with something closer to advertised write speed. 70mb/second is a joke. I only got the OWC brand because people on this board praise the OWC name. Thanks.
