I though both 128 and 256 read speed also same ?
only write speed different ?
anyone tested speed on 128gb?
My 128gb is on the way already lol
Your answer is corrected.
For most 128, 120gb was write speed lower than 240,250,256gb SSD.
Even my late 2012 retina MBP are the same.
To compare from my mid 2012 unibody non retina display upgrade to 250gb samsung 840 Evo much smooth than the retina MBP late 2012 speed for open program when boot up.
The big different you can test was in the About Apple and go to view your storage, these was take you some time to calculating on actual storage you has been usage.
If the faster speed just few second was appear already.
For example here and see how many sec will pop up.
