Just like in previous designs, Apple runs its own custom firmware on its SSDs. I can only assume a TS prefix will stand for Toshiba once again. Just as before, the SM prefix stands for Samsung. I can now confirm that the PM830 is indeed what is used in Apple's SM512E SSD.
In my initial look at the Retina Display MacBook Pro's storage performance I hypothesized that the SM512E part number in my review system was a drive based on Samsung's PM830 controller (the OEM version of what's used in the Samsung SSD 830).
Apple is now using 6Gbps SSD controllers from both Toshiba and Samsung, allowing it to claim support for up to 500MB/s sequential read speed. Unlike previous Apple SSDs, the 2012 lineup sees a significant speed bump. We know at least one of those options is a Toshiba part, while another option is Samsung - similar to how things have worked in recent history. Despite the different, all three systems share the same selection of SSD controllers. The traditional MacBook Pro as well as the MacBook Air still refer to their storage as Solid State Drives. Apple is careful to refer to the SSD in the next-generation MacBook Pro as "all-flash storage" instead of a solid state drive. The 2012 MacBook Air, 2012 MacBook Pro and next-generation MacBook Pro all feature updated solid state storage. One of the top items on my to-do list was to hammer on Apple's new SSD. The SATA cable is the weak link, one of many reasons Apple went to the PCI-e and soldered-in storage.After a week in Taiwan, and a weekend in San Francisco, I'm finally back home and hard at work on the Retina Display MacBook Pro Review. They can be damaged quite easily if the unit is mishandled during assembly or re-assembly. This type of cable can experience cracks in traces due to aging, heat, vibration, impact and abrasion. Those SATA cables are actually not cables but flexible circuit boards, usually mylar, with printed circuit traces taking the place of wires.
As it cools down, electrical contact may once again be restored. As a unit heats up, it expands, and as it expands, the crack widens, eventually forcing a complete electrical separation to exist on both sides of the crack, hence a failure. In the case of an intermittent generic failure, the electrical continuity of a cracked trace on both sides of the crack is very often a function of the temperature of the unit at the point where the crack exists. It is however no mystery why old cables fail when switching from HDD to SSD. Agreed, a new SATA cable is a nominal expense and highly recommended.
