Solid state drives are continuing to build momentum as a speedy and rugged replacement for traditional spinning drive. TDK's ongoing research into mechanical hard drives, however, suggests that we shouldn't give up on the legacy technology just yet. The company...

Mechanical hard drive's are going to be around for a long, long time and the bigger, the better. SSD's are great to host your OS and maybe a couple of commonly used programs. Because of the cost ratio though, everything else goes on a mechanical drive.

For example, I'm ripping all of my blu-rays right now. Well those .iso files take 40GB of room - completely stupid to consider putting those on an SSD. But a 6TB mechanical? Perfect. :)

What I do not understand is. 1.5 tera / inch square. How does that translate to 2 tera per plater. Last time I check a plater has 2 sides. So slam 5 platers like a normal hard drive and you got 10 sides. This translates to a 20 tera hard drive. Not 6. They let anyone write an article nowadays even some one with 3rd grade math.

Apparently they also let anyone post on the interwebs nowadays, even someone with third-grade grammar and syntax...

I completely agree. I love the speed of my SSD for boot time and a few everyday apps but I'll never give up my high density spindle drives until something far better comes along to replace it. I'm also in the middle of converting all my DVDs, Blu-Ray movies and TV series for a HTPC and I'm already scouting for more drive space. I'm drooling over the idea of one of those 48U racks filled with 6TB drives.*nerd*

Just as you think they reached the max storage density on a magnetic drive, news like this comes a long.
I think they had this had technology for a very long time now, but if this would have been released years ago, all the storage manufacturers would go bankrupt, because most people would have had enough storage for a decade.

Actually, this is a small error on the part of the poster. Hard drive platter areal density is measured in Tb not TB per square inch (that's giga BITS vs. giga BYTES). Also, they don't mention if the areal density is measured per side or per platter.

These would have been out years ago, but counting all of the 1,500,000,000,000 bytes took them a few tries. That one joker who calls out random numbers while they counted had to be sacked! :D

This moves with Hitachi's prediction of steadily increasing density to 25-TB 3.5" disks by sometime in 2016. It still baffles me how they can get that much information controlled in such a small area.

The grammar has to be third grade level so Terrorists like Rashan can understand it. So it has to be dumbed down.

Yes I was confused. Already 2.5" 1TB drives. There are also already 4TB 3.5" drives... I can buy the Hitachi 4TB from my local store. Article fact check fail!

Because its 1.5Tbits/sq in not Tbytes. But yes, the TS article failed to make the distinction and used the same TB in both cases, creating a confusing read.

Edit - oops, saw that was covered above. The linked to article has more details.

I'm thinking in terms of how much data I'm looking to lose once such HDD goes belly up.

One needs at least two of these in RAID1 at all times, to feel safe.

In 2014 we'll probably have 10, 15 and even 25tb HDDs.
And people said SDDs would replace them... Lame.

This article is old news. With HAMR we are talking 60 terabyte for 3.5 and 10 to 20 terabytes for 2.5. So this article is like old news. Oh by the way if you lazy to google HAMR = heat assisted magnetic recording. I want those drives now so I can download the internet before it becomes all to censored by all governments. Issues piracy and secrecy of the wrongs all governments are engaged in. Like poisoning the population as genetic research shifts into high gear. They are trying to make you more obedient to be able to convince you that bs is ok.

Actually mechanical hard drives will become obsolete when scientists figure out how to control electrons. My concept is that you could store a zero in an electrons normal excitement state and a 1 in excited state. So this could be atomic storage. The problem is holding electrons in the state. Also one day lasers are going to be so powerful that you could etch something in a protons surface. Same with neutrons. By powerful I mean narrow beam. When we can focus laser so precisely that it becomes a single neutrino wide.

There was someone who mention the time he remembers no hard drives existence and was working with floppies. That was very much a dream when there were only punch cards for computers. And even punch cards were the newest trends where there were only pluggable wires for programming. Some history. How about the time when computers just used gears? Like the anticateria computer for astronomers. It only used different sized gears. Same thing in the Mayan calendar computer. Gears to compute the days.

The reason is It is increasingly tough to stack platters in a drive that still fits the standard bay....

Dude, is it really that much trouble to get up and slap a disc in a DVD player?
