BBAI64 eMMC write speed slow compared to datasheet for eMMC


I noticed that the eMMC write speed is quite low (<25MByte/s) on the BBAI64. From reading the datasheet for the Kingston eMMC used on the BBAI64 it seems that the HS200 interface should support up to 100MByte/s write speed.

Are there any hardware constraints that reduce the speed to only 25% or is it just linux filesystem overhead that limits the write speed?
