HAMR HDDs To Debut At 4TB Capacity But Reach 100TB By 2025

Heat-assisted magnetic recording (HAMR) is a novel process in which a small laser is used to apply heat to a disk so more data can be written to a standard platter. Some thought this was implausible, but Seagate says they will be introducing them next year for testing. Do you think mechanical hard drives are going to stay relevant thanks to these advancements, or will improvements in SSD capacity make them obsolete?

It seems that shipments of HAMR-based hard drives will start in 2018 after the tests started in 2016 probably end in 2017 and demonstrate whether HAMR tech is ready for mass production or not. To beat the rapid advancement of SSDs driven forward by Samsung, Seagate plans to make the new drives available only to select cloud and hyperscale datacenter customers, and only after that, the technology will move to the wide spread consumer market.

what i am not sure is about HAMR performance. will it end up just being another shingle hdd with good reads but not good constant writes. basically just meant for archiving purposes (e.g. videos, music, documents etc etc...)rather than for running your applications directly from (especially if it's something that runs constantly while in use like torrent client for example).

but then again for high capacity, people don't really expect performance, which they already rely on ssds for OS, games, apps... so i think the status quo will stay the same.

and yes i do think that optane ssd has a good chance to trump nand ssd because of the endurance, performance, storage capacity, the process to make is not too expensive (according to sources they speculate pricing to be somewhere between ddr4 and nand pricing. though with scale it might get cheaper).

nand recent developments are increasing the capacity size via 3d-nand, and other methods to cram in more storage space. the only way nand ssd's will still be relevant once optane comes out, is if they can produce nand ssds with high capacities and cheaper. otherwise people will just pass that over and go with octane.

then again like how people would for sure buy 1 single ssd for the os rather than hdd, people may now do the same once octane comes out. so nand ssd will have to take the place of what mechanical hdd was in that sense.

mechanical hdds seems like hamr is the next new thing after helium hdds, and shingle drives to renew the mech hdd platform. they too will be very reliant on having more space on the cheap to stay in the game.

but if you ask me, i think once nand ssds get to around 4, 6 or even 8 tb each, and cheaply, people will just get those and pop them into a NAS and use for storage. but the only downside is, they need to keep the NAS 24/7 operational, or at least scheduled to be on once every week because it was found that nand ssds begin to lose data if left without power over a few months or so. also make sure you only use ssds with some form of protection from sudden power loss, otherwise you are screwed down the line.
anyway about HAMR

i use hd tune 

thank you very much for your reply...

as a normal user, i dont think i want to use the NAS technology and other advance technology...  i just love to read about technolgy but dont have enough money to try use it...... huhuhuhu..

some time if i use my friend powerfull computer that i help him to buy because of my little knowledge, also i dont know what to do to maximize it power... i dont play games, dont know much about video ,picture editing... so my ancient system is far enough for now, maybe in future i will upgrade...

wd 4tb black is for video processing, gamers...new price is about rm800...  normal external casing is rm100... maybe i want to sell it when i get it next week.. i won it from amanz.my website..

confuse..

Nope , I can't run HD tune , there's no smart test or heath tab is totally empty.Try other hard drive is still empty.
What could it be ?

Does doing a full disk scan check reduce the HD life time ?

my drive just arrived....

running the test to make sure it is brand new, also no errors
hdds usually like if says 1tb, you don't actually get 1tb usable space. probably slightly less.

for example my seagate 1tb is actually only 931gb usable space.
also 512 vs 4k sector drives, the later has more usable space on a 2tb+ hdd, because it's more efficient as it uses less space for stuff like error correction etc. so for 2tb+ hdds always get the 4k native models. you only use 512 when using an older OS, which i don't recommend doing
total read 770gb seems a bit low.... can u check whether part of your HDD is unallocated ? i suspect that is the problem for your particular case. to check, either use something like AOMEI's partition assistant app, or, go to computer management in windows and check if the drive in question has any partitions unallocated 
PS: i checked the same properties windows as you, and mine correctly states total capacity is 931gb. so yours is definitely weird 

can you try download aomei partition assistant and check if there is any partitions ?

also try use hd tunes and run a block scan, then view the smart info 

i'm an ameteur as well, but if i had to guess, either it's an unallocated partition, or .... it's bad blocks that have been reallocated which would make the usable space much smaller. The last is just my guess, cause i don't know if it would actually do that 

but what else could it be ?
