After the OWC MacBook Air SSD debacle, I don't think I will ever purchase an OWC SSD again (even if they have stopped using antiquated SandForce controllers). I was disappointed by the lack of quality control, but I was even more taken back by OWC's response.
I was also really taken back by how they initially advised customers to not use TRIM by stating that TRIM could harm their Mac instead of stating that it was a firmware issue on their end that needed to be addressed...
The Transcend 820 will work with your computer, although it does entail some performance loss (for everyday usage, I doubt one will notice the differences.)
