Regardless of falling numbers within the mainstream arduous drive market, Seagate continues to push the envelope to succeed in its 20TB aim by 2020.
Throughout a convention name after Seagate launched its earnings report for the second fiscal quarter of 2017, Chairman and CEO Steve Luczo provided a roadmap of the corporate’s arduous drive rollout over the subsequent 18 months. Throughout this era, the corporate plans to broaden the capability restrict as much as sixteen terabytes (16TB), surpassing Seagate’s present onerous drive merchandise available on the market which might be maxed out at 10TB.
“Our eight terabyte product leads the market in value and efficiency and we’re happy with the ramp of our 10-terabyte product when it comes to high quality, efficiency, and buyer qualifications,” he stated.
Luczo additionally stated that Seagate clients are presently testing its 12TB helium-based mostly arduous drive and offering constructive suggestions. It is going to comply with the 10TB model launched a yr in the past for the enterprise sector, counting on helium to create a turbulence-free surroundings contained in the onerous drive shell for packing in additional spinning platters. These platters are what retailer knowledge, that are learn like a report participant by stationary learn/write heads.
Seagate’s present 10TB helium-based mostly drive consists of seven spinning platters and 14 heads crammed right into a three.5-inch type issue. Helium reduces the quantity of friction and resistance induced when spinning platters are shut collectively. That discount in flip lowers the quantity of energy the drive will pull, reduces the extent of cooling the drive wants, and allows Seagate to extend its capability by cramming in additional platters.
Drives pushing 10TB or extra are sometimes utilized by the enterprise sector or in community-hooked up storage units. Proper now, the most important mainstream-targeted desktop exhausting drive seems to be Seagate’s 8TB STBD8000400 mannequin for $330 whereas the most important enterprise-grade exhausting drive is Seagate’s helium-crammed ST10000NM0086 mannequin costing $466.
Within the mainstream market, mechanical arduous drives are being changed by NAND-based mostly strong state drives (SSDs) as the first storage system. SSDs haven’t any shifting elements and retailer knowledge in cells slightly than magnetically in tracks on a spinning platter. Meaning SSDs are quicker, and ultimate for housing the working system and put in packages, enabling extraordinarily quick system boot and program load occasions.
Within the preliminary days, SSDs have been somewhat costly. However as costs have come down and capacities have gone up, onerous drives have gotten the secondary answer in methods for storing information, music, video, and so forth. Nevertheless, the enterprise sector is a unique story, provided that knowledge facilities principally depend on mechanical drives, and shifting from HDDs to SDDs can be pricey.
Regardless of the declining onerous drive gross sales within the mainstream market, Seagate said in 2013 that it plans to supply a 20TB onerous drive by 2020 utilizing shingled magnetic recording. Seagate in contrast this technique to shingles on a roof, stating that the info tracks overlap one another, thus growing the density of every monitor and the platter’s general aerial density.
Luczo stated within the convention name that delivering exhausting drives as much as 20TB in capability “takes a number of funding, a number of know-how.”
