Using the -noatime mount option will extend the lifetime of the SSD. The final lifetime depends on how heavily the servers are used. If they're used 24x7 and the cache is always changing, you might get a year or two out of the SSD. RAM is fairly cheap these days. Instead, if you can, increase RAM by 16GiB, leave the cache on rotating media, and let Linux cache the files in RAM. After that, performance improvements will come from fixing inefficient code. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
