No spin: Ars reviews the MacBook Air with solid state drive

A lot of reviews of the MacBook Air are starting to trickle in and I think one of the most obvious gripes with this machine is the lackadaisical disk performance. Due to the space constraints associated with the Air form factor, it seems obvious to leverage chip set functionality to improve I/O performance. The Santa Rosa chipset already supports "Robson"; external flash based caches for hard drive operations. If this technology were leveraged to cache writes to the disk, you could have the best of both worlds. Random access speed would be matched by sequential write performance.

Of course, this will probably be mitigated by second generation consumer level solid state drives. But until this inevitability materializes and the cost of SSDs descend from the stratosphere, this seems like a reasonable compromise.
