Common problem by the looks of it https://discussions.apple.com/thread/4052266?start=0&tstart=0
This sounds like the system some SSDs have that if you stress-test them for a "long" amount of time, it will throttle in an attempt to preserve the quality of the cells. That throttle is usually left active for a long while.
Hopefully it's something similar to that.
System Information says: APPLE SSD SM256E - so Samsung, I assume?
I am new to Mac, how do i navigate to the screen that shows this?![]()
I've been following this thread since its inception.
Maybe this is the obvious observation, but it does seem like all the MBA 2012 64/128 SSDs are Toshiba, and all the 256/512 SSDs are Samsung.
Has anyone found an exception to this case? Seems that they've stopped mixing in Samsung SSDs in the 64/128 SSDs like they did in the MBA 2011 models.
