How Important is RPM for Hard Drives


Looking to purchase another 2tb SATA drive for music storage. I'm seeing 7200 rpm drives that are maybe a bit noisier and run a bit warmer than 5400 rpm drives that are cooler but slower. The 7200 drive (Hitachi) may be a tad more reliable than the 5400 Western Digital or Seagate - not sure. I do plenty of backup anyway.

Thing is, with over 1.5 Tb of music, I imagine seek times can be somewhat slow. Once a music file is found, there ae no skips or pauses with itunes. Does the rotation speed matter much for seek times on such a large music library, or is the rpm more an issue for writing/reading higher bandwidth information than music?

Thanks, Peter

I happen to think that speed and cache (and transfer interface) are the most important issues of a drive. I run 10,000 RPM drives, Western Digital Blacks, SATA (RAID). Don't skimp on Hard Drives. Few hundred bucks for hours upon hours of ripping.
