As noted in a recent blog post, OWC was able to get their hands on Apple's latest 13-inch and 15-inch MacBook Pro with Retina display models, both entry-level versions with 128GB and 256GB flash drives, respectively.
In its initial test, the firm saw minimal difference between the two setups, though average random write speed on the 15-inch model was more than twice as fast as that of the smaller laptop. Random reads were also accomplished at a faster clip with the larger model, though not at speeds noticeable to the end user.
OWC's Retina MacBook Pro examples use Samsung SSD modules for the 15-inch (top) and SanDisk with Marvell controller for the 13-inch model.
Flash modules for the 13-inch model are sourced from SanDisk and controlled by a Marvell chip, while the 15-inch version uses Samsung's memory and controller set. The vendor choice mirrors Apple's last update from October 2013.
OWC also went through the unboxing ritual and continued by removing the bottom covers of each laptop, revealing a familiar symmetrical component layout. From the looks of things, Apple has apparently left internal design largely unchanged, meaning the refresh consists mainly of CPU speed boosts and a new standard 16GB of RAM for the low-end 15-inch variant.
