2017 MacBook Pro 13' TB. 1TB SSD. APPLE SSD AP1024J I did some reading and it looks like the first two characters determine the manufacturer - http://osxdaily.com/2012/06/21/determine-manufacturer-of-mac-ssd/ -- TS = Toshiba. SM = Samsung. I guess AP = Apple? So Apple makes its own 1TB SSDs? Does anyone know if Apple hires a company or did they really make their own 1TB SSD? Thanks!
