pointertovoid Posted February 28, 2011 Share Posted February 28, 2011 Hello nice people!The second generation of WD's Velociraptors, with 450GB and 600GB capacity, have more agile arms - though it's not advertised everywhere, their track-to-track hop is 1/3 faster as are short strokes.Nevertheless, neither noise nor consumption have increased since the first generation with 300GB capacity. This is a hint to a lighter arm.I couldn't read an explanation for this improvement. Can you?I had suggested electroforming to produce lighter arms of nickel, some µm thin, there:http://saposjoint.net/Forum/viewtopic.php?f=66&t=2160and sent this idea to the manufacturers of hard disk drives, plus some more ideas, like the two-armed hard diskhttp://saposjoint.net/Forum/viewtopic.php?f=66&t=1793I'd be happy if at least WD has used this idea of electroforming.Thanks!
