Hallo, Ricardo, Du meintest am 14.06.13: > I think that if you can use a good Disc controller (with 1G+ of > cache) and make: 1 Raid10 for the SO with 4 discs > 2 RAID10 for 2 disc_cache storages for squid with 4 discs each (or > even 2 RAID5 with 3 discs each) Sorry - RAID10 decreases the performance, and RAID5 too. A cache doesn't need the redundancy options of RAID. A simple "jbod" configuration (or 1 fast disk, especially an SSD) should do the job. By the way: the squid cache is a short time buffer, no archive. Viele Gruesse! Helmut
