Disk vendors should invest in defrag tech
I am surprised that the existing hard disk manufacturers aren't investing in and giving out free disk optimisation software in an attempt to increase the longevity of "spinning platter" hard disks. Also they should be working with the AV vendors to stop them hammering the disks so much & ruining battery life on laptops.... and MS to stop XP et al pointlessly paging to disk on a machine with 2Gb _free_ RAM... thus making normal HDs look better & reducing power consumption.
SSDs will become mainstream (i.e. when my mum has one in her laptop) sooner or later but for now most people still have hard disks. OS performance (especially Windows) is crippled by hideously fragmented file systems... even on a basic computer an _intelligent_ optimise can make a huge difference to computer responsiveness. Move archiveable files towards the spindle, sort frequently used files, clump frequently modified files & leave some room for expansion... block placement of directories for DBs with expansion room after certain files... etc. etc.
I think users who consider disk optimisers resent the rip off prices some of the vendors charge (especially as some are very poor). Bearing in mind how much difference it can make to a machine & the perceived speed improvement of the hard disk, I am surprised that the disk vendors don't get involved here! Make your tech look better... sell more kit from your existing assembly lines.
