1.well what exactly do the HARD's CACHE memory do??
i mean i do know a little about it but i want some xplantion
2.and if a hard disk has double cache than other one then does it means that the hard with double cache has double speed than other like...
wd 500 gb has 16 mb cache
seagate 500 gb has 32 mb cache
so will seagate perform @ double speed than WD
