The hard drive in my Sky HD box has been clicking when spinning up an down for about 6 months. Although it has been working okay I decided to replace it with a Samsung Spinpoint HD501HI (500Gb Green HD). I spent some time with the specs of the original Maxtor drive versus the Samsung drive and despite the Samsung being a 5,400 RPM performance is comparable; transfer speed, seek and latency Regarding the acoustic management features of the drive though. My understanding is that they effectively slow the drive down and I was wondering if this might affect the performance? Any pointers would be gratefully received.
