I've heard the OWC SSDs are better for people in production (graphic design/video) due to the fact that they don't degrade as quickly over time. How are the Apple SSDs in this respect? I'm trying to decide on whether to get an iMac with the built in 2TB and 256GB SSD option or just get it with a 2 TB drive and add an OWC SSD on my own. One deciding factor is whether or not this will void my warranty or prevent the use of Applecare on the machine. Any ideas? I can't find many reviews on the stability and degradation of the Apple SSDs. There seem to be a lot of good reviews on the OWC drives.
