I have always used OWC SSD's because of the benefits of the SandForce controller: SandForce DuraClass technology with ultra-efficient block management & wear leveling offers highest endurance and performance in a SSD. According to the tests I have read, other SSD's slow down after considerable use. Here is why I am confused: - One post in this forum says the SandForce controller does not work well. A clear reason was not provided. - Others recommend the Samsung 830. Why? I understand that Apple uses that model, but what if I put it in an external enclosure to use a boot drive. I have done this with the Macsales SSD and it works well on a 2012 MacMini. And will adding a Samsung 830 have the same performance as buying one from Apple? - Others use Intel. Some Intel models use the SandForce controller, but are all versions of that controller the same? I would appreciate your thoughts on this. Have scoured the forum and I cannot find an answer. If one exists please direct me to it and accept my apologies for not finding it myself.
