Seagate 7200.11 1.5TB HDD  (Source: Seagate)
Seagate 1.5TB HDD uses four platters

It has only been about a year and a half since the first 1TB hard drives began to hit the market -- Hitachi was the first to unveil its 1TB HDD in January of 2007.

Just this week Hitachi unveiled its second generation 1TB HDD with a 43% power savings compared to the first generation. The Hitachi drive uses three platters to get the 1TB capacity and save energy. Today, Seagate announced the world’s first 1.5TB desktop hard drive called the Barracuda 7200.11 1.5TB.

As you can gather by the name, the drive spins at 7,200 RPM and uses four platters to reach the massive 1.5TB capacity. Seagate says that this is the largest increase in storage capacity in the last 50-years and the 500GB increase in capacity is thanks to improved perpendicular magnetic recording technology.

Along with the 1.5TB 3.5-inch desktop HDD, Seagate also announced new 500GB 2.5-inch HDDs for use in notebooks. The 500GB notebook drives will ship in 5,400 and 7,200 rpm varieties. The drives are known as the Momentus 5400.6 and Momentus 7200.4 HDDs. The 5,400 RPM drive uses an 8MB cache and the 7,200 drive has a 16MB cache.

Seagate executive VP and general manager of Personal Computer Business Michael Wingert said in a statement, “Organizations and consumers of all kinds worldwide continue to create, share and consume digital content at levels never before seen, giving rise to new markets, new applications and demand for desktop and notebook computers with unprecedented storage capacity, performance and reliability. Seagate is committed to powering the next generation of computing today with the planet’s fastest, highest-capacity and most reliable storage solutions.”

Seagate announced in 2006 that it expected capacity of HDDs to hit 2.5TB by 2009. The Seagate 1TB HDD was announced a bit over a year ago in June 2007.

Seagate says that this is the largest increase in storage capacity in the last 50-years...

*scratches head* What kind of hard drives were they making in 1958? Why not go ahead and claim it was the largest increase in storage capacity in the last 250 years?

They were extremely large physically and using drums instead of platters that I recall. As well as being very spendy and low capacity by current standards (as ours will be described in 50 years).

Indeed. You actually pulled the platters out and put them in a protective film and stored them. It was cheaper this way than getting entire drive units. LOL! My how the times have changed.

Some locations still use RAMACs, as it's been cheaper to continue using them, then replacing them. For the most part though, they are long gone. Last one I've seen still being used was in 2001. We bought the RAMAC to replace our really really old DASDs.

We actually had one of those old disk platters awhile ago, from the early 70's. It was about a yard across in diameter, and pretty heavy. When they said 'mount' the device, they meant the operator literally lifting a platter into the drive spindle unit to get it ready. This particular one had a bad head crash, with physical grooves worn into the metal surface. Pops had it stowed in the garage as a momento.

Anyway, we had thought about putting it onto a sturdy post and making it into a little coffee table or something.

Holy crap, I want one! I never realized how large the platters used to be.

The first HD-platter used in DK was made by IBM. Its ~2" thick(!) and a diameter of ~1 meter and a weight of ~200 Kg. The amount of storage - hold Your breath - 2 MB :)))

(It can be seen in the Tycho Brahe Planetarium in Copenhagen).

The US put a man on the moon, with a flight computer boasting 32K of ram... uber massive for the day.

And I think i read that the calculating capacity was approx. like a C64 :)) Yes, very great accomplishment indeed!

"Hey dude! How's your new HDD?"
"Pretty cool, now I got a ton of storage! *happy*"

- "Does it work?"
- "Yes!.....", *click - discs spins up*
- "And the noise from those 5 washingmachinesized motors, I tell You: Pure music :)"
- "What??"
- "TECH-WHAT???"

*minutes passed by and the whinning sound of the motors was getting pretty obvious now!*

10 minutes later the platters had stabilized, and I was dropped dead by the 130 dBs of the klacking heads.



It's amazing how technoligy has evolved. And then we whine over some 5% slower something ;)

Speaking of head crashes, my former computer teacher used to tell of one that resulted in a shard of a platter flying across the room and being lodged in a wall, where it was left for posterity. Data storage used to be dangerous business.

Me and a friend once did a roll on the floor for fun. I have never in my life seen anything dissapear that fast. seriously. And we are talking 4200RMPs. Imagine a VelociRaptor at 10.000...

Good question. It can't be percentage increase - the last 50% percentage increase was the 500GB to 750GB jump circa a few years ago. It could be overall capacity increase - a 500GB jump in one generation would obviously be the largest on record - but then what happened like that 50 years ago?

Does anybody know the *specific* platter density on these things? It may be that there's just enough actual percent difference because of an obscure platter density to market it as being slightly over a 50% increase...

It was just a bad way of saying it... He should have said "in the 50 year history of hard drives" or something similar.

Its probably the largest increase in recording density per square inch in a marketed device.

I examined patent applications drawn to magnetic media for the better part of 4 years, and am proud to say I issued many of the patents that are now the basis of Seagate's perpendiuclar hard drives.

Granted, this was several years ago, but the applications I examined were quoting storage densities of 20-50 GB per square inch. Those numbers seem in line with current products. E.g., one 3.5 inch platter has an area of ~9.6 square inches. If Seagate is using 4 platters to reach 1500 GB, then each platter stors 375 GB, or roughly 39 GB per square inch.

The first hard drive debuted in 1956 as the IBM 350. Additionally, the comment described STORAGE increases, which includes hard disks, as well as other formats. This IS the largest storage capacity increase for a single device ever, absolutely (500GB) and relatively (50%.)

That's a lot of data to lose when one of these crashes.

I think they were something like this one
