USB keys are the cheapest available storage. CF cards are much better quality, faster and more reliable if you get the good ones. I haven't had the misfortune of doing any serious testing of SD cards, but I have had one fail in a phone out of 4 phones running SD for a few years - a much worse failure rate than hard drives but a statisticly insignificant test sample. > The other problem I had was that stock installs will want to fsck > after an outage, and even with a journal that's suckily slow. > (Especially when you're talking over the phone to a non-technical user > who is reading boot output off a 19" monitor balanced in their lap or > whatever. You know -- the usual.) One thing to do when creating an ext3/4 filesystem is to use a much smaller number of Inodes than the default. Ext4 has significantly improved things over Ext3 because it won't needlessly check Inode block groups that are unchanged but I think that having fewer Inodes still helps. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
