Seagate announces "world's first" 16TB 3.5-inch hard drive

Seagate announced that is has achieved another milestone with its heat-assisted magnetic recording (HAMR) technology. It claims to have successfully tested the “world’s first formatted and fully functioning 16TB hard drive … in a standard 3.5-inch form factor.” The company predicts that it could exceed 20TB before year end 2020.

The new HAMR-based version of its Exos drive is aimed squarely at enterprise customers for now. Its tests have confirmed that it functions as any other plug-and-play enterprise drive on the market. Therefore, no changes to current data center architectures are required to integrate the new drives.

“Seagate has begun running early Exos HAMR units through the full set of standard benchmark tests used to prepare and optimize each new hard drive product for deployment,” said Seagate’s Senior Director of Enterprise Product Line Management Jason Feist. “Our testing has demonstrated the drives’ compatibility for enterprise systems that are being used today. No system level changes are needed to run the HAMR drives in these evaluations, or to deploy them in customer environments.”

Seagate’s HAMR technology uses a tiny laser diode on the recording heads to heat a spot on the disk. This technique allows the recording heads to flip the magnetic polarity of each bit written. The data bits, or “grains” as Seagate calls them, can then be packed more densely onto the magnetic media while remaining extremely stable.

The newest HAMR hard drive is still in early testing, but so far Feist says it is meeting all expected benchmarks including power efficiency, SCSI device command tests, and “several four-corners tests,” which focus on read, write, random, sequential, and mixed workloads.

Seagate does not yet have a launch window or price set for the 16TB drive. However, with its 14TB Exos drives having just released in September and its focus on a 20TB sometime in 2020, we can probably expect the enterprise device sometime next year at a fairly hefty sum.

There is no word on a consumer-level equivalent at this time, but as indicated by Senior Vice President of Global Sales and Sales Operations BS Teh in the above video, the consumer market is part of Seagate's vision for HAMR drives.

Will be great for RAID configurations .... assuming anyone will be able to afford them .....

Depends.

Massive arrays take forever to rebuild. If you're using something like Ceph instead of RAID, then it will probably work better.
 
This is a small, expected, incremental increase in capacity. Why is this news?

And by the time the hit the (yay?) 20TB mark SSDs will be the norm for enterprise.

The only way for them to die is for a hacker/exploiter/script kidde to steal some basic code from forensics and steal a single ssd. SSD's are hard to wipe (truly delete stuff) while hard drives are easier. Not to mention ssds are way to expensive. Why pay about 200 extra for a ssd just for speed.
https://amzn.to/2KQMg7O ssd vs https://amzn.to/2a7pFAV hdd. I just googled 1 tb hdd and 1 tb ssd

Your example is so wrong, as Evo 840 is EOL for years hence price is totally wrong. Latest EVO 860 for 1TB reached U$120 here in Australia after cash back promo from Samsung, with longer warranty and life expectancy than most consumer HDD.

And price is going down almost daily for SSD. Just 14 months ago I paid twice as much for EVO 860 1TB and 4+ years ago 4 times as much for EVO 850 1TB.

SSD's are the future.

HD manufacturers are finally getting their head in the game.

Seagate, can I have a hard drive with this size but with reliability of an SSD drive?
I know why you have 1-2 year warranties. Because these drives fail often.
My last hard disk was from premium WD series and came with 5 year warranty.
I am telling you, this will be my last hdd when it dies.

Makes me think, is there a technology like hdd but without moving heads? I think it would be more reliable if existed.
