Be sure that you have a distro that uses Linux 2.6.x. Apparently this is where SATA support first came in. Some distros may have backported the drivers to 2.4; perhaps other people on the list may know which ones have support. > 3.

Just keep a spare drive handy for such an event though... Remember that a web cache contains essentially disposable information; stuff there is erased and rewritten on a nearly constant basis. Reliability is a secondary consideration for this application; speed is of the utmost importance, which is why people were using ReiserFS for web caches even before it was widely considered stable. Maybe RAID 0 (striping) would be a good idea, because the parallel reads it allows may significantly improve performance, but RAID 1 is a waste of resources. Your disk could die, true, but so what. Your only loss there is a very brief period of downtime, not data. -- dido Sans les mathematiques on ne penetre point au fond de la philosophie.
