Inside the Plextor 128GB SSD:

While it is probably as true in the world of technology as it is when it comes to people, "beauty is only skin deep" and "It's what's inside that counts."  To this end we rarely leave hardware alone and often void warranty by pulling devices apart to see what is inside and what makes them tick.  We treated the $400 Plextor just the same as another other piece of hardware and proceeded to pull it apart and discovered that the drive is not in fact milled from a solid block of aluminum but is cast, then finished to appear super high-end.  That being said, it doesn't matter in overall quality or ruggedness.  SSDs are tougher than regular mechanical drives and as long as the parts are protected it should be good to go.

Plextor has used all of the available space inside this SSD and crammed both sides of the PCB with Samsung K9HCG08U1M-PCB0 51nm NAND flash chips.  The drive is buffered by a 64MB Hynix HY5DU121622DTP DDR400 module that provides more than enough buffer for a drive of this speed.  The flash is controlled by the Marvel 88SS8014-BHP2 controller that remains fairly mysteries at this point.  There really isn't a lot of information on this controller, but we've seen it used in other drives that aren't super high performance.  It seems to be a reliable part and is found in "Strong Page" drives that have continuous performance, high-reliability - albeit, mediocre performance.

Before we head on over to the next page and begin testing, we have a close-up of the Marvell controller.

The Marvell controller goes by the codename "Da-Vinci".  I'm not sure why this is the case as it certainly doesn't have the talent to paint like the master, but it sounds impressive - much more refined that the Indilinx "Barefoot" controller.
