The only reason for extend is more capacity . Currently there is no problem with current setup except capacity . I can replace each SSD with new 500GB which doubles the capacity and it is not enough . and old SSDs will be unusable . So i prefer a long term solution like NAS . Current spec of squid boxes are core i3 (with current 3.1.20 version one core utilizes) and 16GB of ram . so far so good . -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Hypothetically-comparing-SATA-SAS-to-NAS-SAN-for-squid-tp4664350p4669531.html Sent from the Squid - Users mailing list archive at Nabble.com. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
