Windows only needs to be able to read/write data, period. It could careless whether that data is on a sata drive, an IDE drive, an optical drive, a striped array, ram,etc. On a striped array, the addresses are split to be physically alternating between the 2 drives (or more in a matrix) and is controlled by the Raid controller. Windows has no idea where the data is coming from and doesn't care. Look at pagefile, windows doesn't care if it's your hard drive or ram that holds the data, it just asks for data to be retrieved and for data to be written. If you defragmented your hard drive, it will attempt to defragment it the exact same way it attempted to write it initially...by sequential addressing.
