If transfer speeds for sequential large files are slower for the RAID 0 SSD when compared to 3.5" plates-based HDs RAID 0, performance for random read/write of small size files are much faster with the solid state unit than the Raptor. Such feature would be very interesting as a system disk, as OS X spends its time to write and read small files. This explains why the Japanese website reports that the system was much more reactive with a RAID 0 SSD than with a RAID 0 Raptor. Ideally, one would need a computer using SSD as a system disk and one or several plate-based HDs as a storage volume for data.
For notebooks, it will be different as performance level of SSD is almost identical to the ones obtained from 2.5" HD. This is really the main market targeted by SSD manufacturers, as SSD will also extend battery lifetime and provide higher reliability and silence.
