Sorry I have only seen the 4TBs. Seagate did announce in August that they are expecting to launch a 4 platter 5TB drive in 2014, but as to when next year is anybody's guess. Here is the press release from Seagate http://www.seagate.com/au/en/tech-insights/breaking-areal-density-barriers-w ith-seagate-smr-master-ti/
That's an interesting article. A capacity improvement of 4TB to 5TB is rather disappointing though, I would have hoped for something more with such a change in technology. Also from the rough description given it seems that the probability of a write going wrong and corrupting unrelated data is going to increase a lot. ZFS with regular scrubbing should be able to deal with such things but it's still a concern. It makes me wonder whether I should move to RAID-Z2 on more systems, in which case 5*5TB would give 15TB of usable capacity in RAID-Z2 as opposed to 5*4TB in RAIZ-Z1 giving 16TB usable capacity. It would be nice if someone started manufacturing 5.25" hard drives again. With such a size it should be possible to get 10TB or more on a drive. It would be slow but I've got clients who need such mass storage and don't really care about performance. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
