So far that can only be said for reads, and then only for sequential requests we still have not seen any write access time reports, nor have we seen any random read/write access time reports to really compare. With that in mind the known quantity of a sas drive (15K 2.5") of 2.9ms read and 3.3ms write for access times (average) has the upper hand at least until someone can produce #'s for the SSD's.
