Temperature variations between my server’s HDDs

In December 2009 I rebuilt my home file server to be a FreeBSD 8.x machine with six 1.5TByte Western Digital HDDs in a ZFS raidz2 configuration. From February 2nd 2010 I’ve been sampling the internal SMART temperature senors of each drive every 6 minutes. This post summarises some of what I’ve captured. Advertisements
