Just bought a Base 2012 13" from Best Buy (Only $999). Opened it up to find that I have a Samsung display and Toshiba SSD. From what I have read, Toshiba is slower when filevault is enable or used. However, from the write tests, lots of Samsungs go over 400 while the Toshiba range from 250-370. Mine is writing at around 360ish right now. Is it true that given time, Toshiba SSD's have a tendency of slowing down?
