14x 256gb MLC SSDs in a raidz2 array have worked fine for us. Performace seems to be mostly limited by the raid controller in operating in JBOD mode.
Raidz2 allows sufficient redundancy to replace any MLC drives that develop issues and when you have that many consumer level SSDs, some will develop issues until you get all the weak ones weeded out. If I had more space in the box or didn't need quite as much space I would have split the array into 2 or more striped raidz2 arrays. Your mileage may vary. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
