According to 9to5Mac, Apple might have chosen Samsung and its SSD 830 for its next generation MacBook Pro. This is a good news as such recent models are about twice faster than those currently proposed by Toshiba. However, Samsung units are not the fastest SSD, the Vertex 4 and the forthcoming models to be released in a very near future will offer performance levels saturating the SATA III interface. 


The good news in this rumor is that beside getting slimmer, the future MCB and the SSD 830 will still feature a 2.5" enclosure, so we will not be depending on an exotic and proprietary solution from Apple for SSD.
