My initial plan was to get two 256GB RealSSD C300s (after they fix the firmware) and run them in RAID 0 in the MacBook pro as I need more than 256GB of storage. But now that Apple is offering a 512GB SSD option, i'm considering that as well... What kind of SSD do you think is in there? I'd love to have a single SSD, instead of having to rip out the optical drive and RAID two smaller ones... but... I'm concerned that Apple isn't going to be using the highest performing SSDs, which they typically haven't.
