As a home user, here are my thoughts. WD = ignore (TLER issues, parking issues, etc)
I recently built up a server on Osol running Samsung 1.5TB drives. They are "green", but don't seem to have the irritating "features" found on the WD "green" drives. They are 5400RPM, but seem to transfer data plenty fast for a home setup. Current setup is 2x6-disk raidz2. Seek times obviously hurt, and ZIL caused so many issues that I turned it off. Yes, I know I might lose some data doing that, yes, I'm OK with the tradeoff. The ZFS devs say I won't lose filesystem consistency, just that the write cache could be lost, about 30sec of data in most cases. As it's on a UPS and the rest of the network isn't, or is on small UPSes, it will be the last box online, so any clients will probably have their data saved before the server goes down. The next upgrade is a UPS that can tell the server power is out so it can shut down gracefully. I'll probably get an SSD for slog/l2arc at some point and re-enable ZIL, but for now, this does the job as SSDs that don't have similar issues when used as slog devices are rare and expensive. If the X25e won't do... This setup with the 5400 RPM drives is significantly faster than the same box with 7200RPM Seagate 400G drives was. Of course, those 400G drives are a few years old now, but I was pleasantly surprised by the speed I get out of the Samsungs. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
