Does anyone know what the read write speed on the new MBPR 13" Late 2013 model is? I've search through most thread but cant find the speed for the 128GB model, most of them are 256gb. I am looking at buying a 128gb version and want to compare with my current air model (128gb also) which has 400MB/s Write 700MB/s read. Will I expect the same speed given they are both PCI-E and same size? Ive read that the new MBPR have different SSD (Sandisk potentially) and may be different speed, but I cant find exact data on this.
