tucansam Posted March 7, 2017 Share Posted March 7, 2017 I am trying to plan some future upgrades, and have been reading some articles on hard disk roadmaps from various companies. HAMR technology seems to be something discussed often, but most of the comments on these articles are filled with folks hypothesizing that mechanical disks will be forever limited in capacity, while SSDs will continue to come down in price and also increase in size. I've seen 10TB spinners, but can't seem to find anything indicating larger mechanical disks are on the horizon (I am still searching so feel free to post links I've missed). Quote Link to comment

c3 Posted March 7, 2017 Share Posted March 7, 2017 (edited) There was a trick question last year, what's the largest disk you can buy? The answer is the Samsung 15.3TB SSD. This came as a surprise to many as they tried to defend their answer of 10TB, but the reality is the 15.3TB goes exactly where the 10TB answer was. This is the TB/unit question, which is really, not meaningful. So, the new questions are what is the best $/TB or $/iop? You need to understand what you are looking for, and ask the right question. As you mentioned HDDs have several technologies on the roadmap which will allow for increased capacity/density. These will continue the $/TB curve where HDDs have the lead. On the other side, SSDs are adding things like compression and duplication. It is quite the competition. The first to vanish is the SAS or high performance HDDs, 10k, 15k. HDDs are becoming purely a capacity play, $/GB. Next, desktops and laptops will contain SSDs. Frankly, I am surprised how many are still listed with HDDs. To answer your question, no HDDs are not going away. But you probably wont be seeing them. They are moving into the data center, which is where most >4TB HDDs are already. And in this space, the question becomes how many TB/U and $/TB. 4U for a PB? done Seagate, Hitachi, and WD are in the packaged HDD business. Once HDDs are out of the laptops and desktops, these packages will become of the focus of the $/GB and TB/U optimization. One of the first things to go will probably be the 3.5 inch z height. More platters per (spindle motor)+(head servo) is a great way to drive down $/TB. Edited March 25, 2017 by c3 typo Quote Link to comment
CyberSkulls Posted March 7, 2017 Share Posted March 7, 2017 As far as drives larger than 10TB, HGST announced last year 12TB and 14TB drives would be coming this year.I've said this many many times over the past five years. Spinners aren't going anywhere and will continue to get larger. SSD's will eventually outpace spinners in raw size but they won't replace spinners till their prices come down. When you can buy a 10TB SSD for $400, I'll be interested. Till then, spinners will stay in my chassis. That's not going to happen for many years.

TSM Posted March 16, 2017 Share Posted March 16, 2017 We're probably decades away from consumer devices that could use this technology, but still very interesting. http://www.zdnet.com/article/single-atom-magnet-to-pave-the-way-for-smaller-and-denser-storage-devices-ibm/ Quote Link to comment
garycase Posted March 16, 2017 Share Posted March 16, 2017 Certainly agree => spinners are going to be the choice for serious storage; but SSDs will rule desktops and storage where cost doesn't matter. But I doubt folks on this forum will be building 100TB arrays using SSDs anytime soon Quote Link to comment
garycase Posted March 16, 2017 Share Posted March 16, 2017 ... I suppose the answer to the question ["Are mechanical disks going to fade away?"], however, is, from a consumer's perspective, Yes. I think virtually all laptops and a very high percentage of desktops will ship with SSDs within a couple of years. But for applications with large TB capacities -- data centers, major corporations, etc. -- spinners will still be around for a good while -- at least until (as noted above) the cost/TB becomes much more competitive. Many of us would easily pay double the cost/TB for SSDs, but most won't pay ten times the cost. And even double the cost would require a bit of thought if the sole purpose was archival storage that's rarely accessed; or a media server that only needed enough speed to stream a movie or two.

kizer Posted March 23, 2017 Share Posted March 23, 2017 Wow all this Talk about 10TB drives. I better get that old 500GB Spinner out of my Array some day. Lol Quote Link to comment
