I would like to know difference between IDE and SATA hard disk drives.
Different interface. Same internal components. SATA has a brighter future, IDE will be phased out. SATA allows for higher data transfer rates. SATA has a thinner data cable than IDE.
The maximum transfer rate of PATA - aka IDE, ATA is 133
SATA starts at 150 and goes up from there.
SATA II is 300
The cables are smaller, and there is no "jumping" or slaving of drives.
