i have a wd green 500gb hdd ,64m cache and i noticed that its slow from downloading using steam, disk usage was only 1 or 2 mb so i did a search for it and results with the same hdd was very good with most people at the same ( exact same) hdd but when i did a benchmark 4 times using diskmark it wasnt good enough and i think its my sata cable its an old sata 1 cable and i think that is the problem i did optimize the hdd using windows tool with no effect my hdd is brand new and i dont know what to do
