New Storage Roadmap shows 100TB HDDs in 2025
A very interesting roadmap has surfaced. You guys know, we recently tested the really nice Seagate Barracuda Pro 14TB HDD (review), 14TB huge right? Well, a roadmap from Seagate has surfaced showing their plans and intentions as they are working on 48TB and if you follow that trendline on the roadmap, 100 TB HDDs in 2025.
For that to be able to work Seagate will apply heat-assisted magnetic recording which is also referred to was HAMR, a technology that has around since the late 1990s. HAMR is a way of shrinking a disk drive's magnetized bits beyond the limits of current PMR (Perpendicular Magnetic Recording) tech, in which progressively smaller bits become unstable with error-prone bit values. HAMR is a technology that over time will enable a big increase in the amount of data that can be stored on a disk. A small laser is attached to a recording head, designed to heat a tiny spot on the disk where the data will be written. This allows a smaller bit cell to be written as either a 0 or a 1. The smaller bit cell size enables more bits to be crammed into a given surface area — increasing the areal density of data, and increasing drive capacity.
Seagate wants to sample the first hamr samples to its partners before the end of 2018. Seagate foresees that within five years it reach capacities of the 50 terabytes. By further developing hamm to hdmr ( heated dot magnetic recording ) something 100 TB is in reach. Meanwhile Western Digital ops an alternative energy-assisted recording tech. MAMR, or Microwave-assisted magnetic recording. WD expects its first commercial MAMR drives to be released sometime in 2019.

In before people start bitching about hard drive crashes!
YAY! ACHIEVEMENT UNLOCKED!

those new tech mamr and hamr
wonder how it effect to reliability... before with pmr, platter wearing from magnetic seems close to none
i have to heard a hdd error because it lost its magnetic capability
but now with heated and microwave, by using heat, from it sounds it can permanently change the platter, so i wonder if the platter going to develop badsector more easily after many write compared to pmr tech or not ?
from the articles i read so far, the reliability are about same
especially for WD mamr, i think tech-wise is better that hamr

but we have yet to prove it ourself i guess

Kinda makes sense - as SSD prices continue to drop, there's becoming less and less of a reason to use HDDs. So, the only way forward is to increase their capacity in a way that SSDs can't keep up with, at least in an affordable manner. 100TB HDDs are the only logical way forward.
The interesting thing is with such high data density on the same size platters, this ought to make sequential read times fast enough to compete with SATA SSDs. I figure drives like this will be very appealing to people who edit videos in 4K+, 3D, or ultra-high framerate (for slow-mo). All these people need is a crapload of storage with high sequential read speeds, and that's exactly what these drives will offer.

I think this kind of density only makes sense for server and cloud usage.
The average user only needs 1 to 4 Tb of storage and the content creators would rather have more than one place where to store data.
I have all my data backed up in a 3Tb HDD that I turn on once a month to back up some stuff. I'd rather buy multiple drives over having everything on a single drive.

"Well a roadmap from Seagate has surfaced showing their plans and intentions and they are working on 48TB and of you follow the trendline on the roadmap, 100 TB HDDs in 2025."
So they will create a time machine and go back in time to deliver high capacity drives, that's amazing from seagate! The best company ever!
Ok, ok, you have a typo in there ;-)
