SATA or IDE (Hard Drive)

Which one is better?

Why is IDE costly, e.g.

320 GB WD or Seagate SATA is around 4300rs & IDE is around 5300rs

Dont know about the difrnce. do google, butim using sata one right now from like 3 years. still working :)

ide is old technology thats y it is costly...

like ddr rams are way more costly than ddr2

sata is way more faster than ide giving transfer speeds upto 3Gb/s...

soo go for sata........
