Regarding vdevs and mixing WD Green drives with other drives, you might find it interesting that WD itself does not recommend them for 'business critical' RAID use - this quoted from the WD20EARS page here (http://www.wdc.com/en/products/Products.asp?DriveID=773):
<i> Desktop / Consumer RAID Environments - WD Caviar Green Hard Drives are tested and recommended for use in consumer-type RAID applications (i.e., Intel Matrix RAID technology).* *Business Critical RAID Environments – WD Caviar Green Hard Drives are not recommended for and are not warranted for use in RAID environments utilizing Enterprise HBAs and/or expanders and in multi-bay chassis, as they are not designed for, nor tested in, these specific types of RAID applications. For all Business Critical RAID applications, please consider WD’s Enterprise Hard Drives that are specifically designed with RAID-specific, time-limited error recovery (TLER), are tested extensively in 24x7 RAID applications, and include features like enhanced RAFF technology and thermal extended burn-in testing. </i> Further reading: http://breden.org.uk/2009/05/01/home-fileserver-a-year-in-zfs/#drives http://opensolaris.org/jive/thread.jspa?threadID=121871&tstart=0 http://jmlittle.blogspot.com/2010/03/wd-caviar-green-drives-and-zfs.html (mixing WD Green & Hitachi) -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
