Brand New MacBook Pro Retina Hard Disk Type;

I'm looking to buy a 15" Retina MacBook Pro, I'm looking at the website Models and they seem to be pretty inflexible (for instance the 2.3 GHz model you are locked into a 256 GB HD).

So I know this is a little preemptive, but I want to know how the hard drive is configured. For instance, on my current MacBook Pro I swapped out the standard hard drive for a 480 GB SSD. If the new thinner model has a standard SSD I will buy the 2.3 GHz model and add larger hard drive. My worry is it will use a proprietary hard drive like those found in the Air in which case I would be forced to buy the 2.6 GHz model just to get the larger storage I suppose.

Does anyone have any info on this?

Yes. Definitely. SSD is an important factor for determining the performance of your MacBook Pro. A traditional HDD is more like a record player and it has a spinning platter. The faster the platter spins the more the RPM for the HDD. The only advantage of HDD is that it’s very cheap for huge amounts of storage. SSD’s are not that cheap when compared to HDD. In the case of SSD, there is no spinning platter. It works like the RAM in your system but uses something known as NAND based memory. Here the data is written into electrical blocks. So whats the advantage of using SSD in MacBook Pro? In SSD you get speeds between 300 - 500 Mbps whereas in HDD the speed is only between 50 - 100 Mbps. So if you are using a SSD for your MacBook then the read speeds are increased by 5x - 10x times faster. This makes a huge difference when running your Mac: opening documents, starting programs and even booting up all happen much faster.

The flash modules and controller of the SSD are blades (think naked SSD). They are not up to 3rd party configuration (at this time), but according to bmike, they are not soldered onto the main board and are actually discrete components.

However, there is no information as to what kind of proprietary (if any) configuration the blades come in, or whether they require an additional proprietary onboard controller (this may be likely given Apple's tendency to create speciality hardware for their line-up). So it most likely isn't the case that one could just crack open an existing SSD and use the blades within. A manufacturer would have to specifically design a unit for the new notebook. This isn't unlikely, but price will be the determining factor as it will be a speciality component.

It is also not clear at this time if Apple will make the components upgradeable, which is also a distinct possibility given how quickly SSDs are saturating the market place.

At best, it's a tentative "maybe."
