SSD Posted January 14, 2016 Share Posted January 14, 2016 http://www.seagate.com/about-seagate/news/seagate-unveils-10tb-helium-enterprise-drive-master-pr/ No mention of cost. This thing is going to be expensive! Seems to me that SSDs have gone from 64M to 2T with drastic reduction in $/G in the same time that spinners have gone from 4T to 8T with meager cost reductions. And SSDs have no practical upper limit on size. The HD guys had better start competing in the SSD market or hire some damn good engineers to figure out how to double and then double again the HD capacities, and continue to drive down cost, or the SSDs will be knocking on the door before you know it! With no mechanical wear and potentially a very long lifetime compared to spinners, SSD may turn into tremendous value play for unRAID servers over the next 5 years. Quote Link to comment
demonmaestro Posted January 14, 2016 Share Posted January 14, 2016 While SSDs are nice for R/W speeds the Regular HDs still have a long history of not failing for long term storage. The life span of a SSD is still too short against a regular HD. Just my 2¢ Quote Link to comment
CyberSkulls Posted January 14, 2016 Share Posted January 14, 2016 I would have to agree with demon. As an example the new Samsung 16TB SSD sounds good in principal but none of us can afford it so when you look at normal priced SSD's that are affordable to the general public, spinners will be around for a long time simply from a cost standpoint. Now when 10TB SSD's become viable for long term data storage at $300, wake me up. Till then I will continue to use spinners. I do have to wonder what we will see in terms of spinner price and density in the future. It seems unthinkable that WD or Seagate will release a 15TB or 20TB drive. But they will have to in order to remain relevant. It seems unthinkable but we all felt that way about the first 1TB drive all those years ago. Quote Link to comment
demonmaestro Posted January 14, 2016 Share Posted January 14, 2016 That is why I was talking about drive longevity. Although I do have to say that SSDs will pass HDs in price per TB but till they get the longevity thing figured out that is when things will get interesting. Although there are still BIG company's out there that is still using TAPE for there backups. Quote Link to comment
c3 Posted January 14, 2016 Author Share Posted January 14, 2016 I think bjp999 is correct in the longer term, spinning rust will vanish from the storage spectrum. Tape continues on the long end as the density continues to increase (quicker than HDD). Specialized optical is working to compete with tape. Quote Link to comment

Until Limetech can determine (or implement) background TRIM / Garbage Collection does or does not clobber Parity SSD's are not viable for unRAID arrays. Quote Link to comment
SSD Posted January 15, 2016 Share Posted January 15, 2016 SSDs can and do wear out with write cycles (much better than the used to be, but still happens), but the nature of unRAID is that the media drives are nearly WORM. So unRAID data disks wont have the kind of heavy write cycles that cause the wear. I would think that SSDs would have very long lifetimes if writes were scarce after the drive was filled. If an SSD cost twice as much but has a significantly longer, trouble free lifetime, maybe they will be worth the premium. Is there any reliability data on SSD lifetimes if writes are few? As for the TRIM function - necessity is the mother of invention. In other words, when it is needed it will come. Quote Link to comment

I believe the time is closer than most think. Wasn't someone experimenting with a SSD as an accelerator drive? Quote Link to comment
