The 6Gbps speed is to the DRAM buffer on the drive, and the 263 MBS is the max speed to write to the physical platters on the drive. So what happens is you can have a burst of speed at the 6 gbps of anything less than the buffer size (256mb for this drive I think, or maybe half the buffer size depending on how they partition it for read/writes) then the drive writes from the buffer to the disk at the slower speed. So sporadic small files writes are fast, but if you are reading or writing large files it's going to go at that lower rate.
