I don't know if I would call it that extreme; even the slowest solid state drives are far quicker than the fastest enterprise grade hard disk drives. We have the original 64GB and then the 128GB SSDs used in the first gen air and they have had almost no size shrinkage, but they certainly are not as fast as they originally were. Even their original speeds couldn't hold a flame to the SF driven SSDs and the new MBA has a SandForce upgrade option from OWC which we will probably purchase (almost 500GB SSD!). Indeed the SSD prices from Apple are not worth it, as you pay more for less. Also, I would agree that the SandForce 1200/1500 controlled systems have the best wear leveling software today, but the C400 uses an updated Micron design, and Samsung has also changed their controller design. The C300, which IIRC is Micron controlled, does have good wear leveling as well, although my personal preference is SandForce all the way. Without a doubt, the SandForce driven solid state storage systems are among the, or are the, fastest of all data storage systems.
