pros: low power, runs very cool. Quite fast for a 5400rpm drive. Long warranty. I think this drive, being so cool, will last many years. Samsung e-mail support is quite good.
cons: silent, but clearly more noisy (idle) than the Barracuda ata IV. (Ball bearings produce a high pitched sound. not very loud, but noticeable anyway). Also, the motor produces a
low frequency vibration that resonates with the chassis. So, this hard disk is not as silent as I would like. Also, I think noise increases as months pass. I think Samsung needs URGENTLY to get fluid bearing motors!!
Nowadays the Samsung is more expensive than the Barracuda ata IV.
Conclusion: if you need a cool, relatively fast, and reliable drive, this drive could be your choice. But it should be 15% cheaper.
