Gd morning all, I have noticed in some (at least one) recent postings with description of a system which included only one large disk media. Some time ago when I first explored the pleasures of building my own proxy I learnt that better performance could be obtained from the technology of the time by building the cache storage on a disk system seperate from the OS, and logs, and built with multiple small disks. With advances in disk technology does such a concept still apply ? Or do larger disk caches, higher access rates and other improvements mean that such tricks to reduce average seek times for cache reads are less important on busy machines. cheers Graham
