The Effects on Read Performance from the Addition of a Long Term Read Buffer to YAFFS2
By Sam Neubardt
Hard drives have much smaller sectors than flash memory, which does give them a slight advantage in performance. While the data on a hard drive can be changed many times without causing physical wear on the drive, the data on a flash memory device can only be changed a certain amount of times (often over 500,000 times per page, but it still adds up) before the reliability of the drive starts to corrode.
