Disk capacity growth rate slowing
The Register ^ | 3rd February 2010 11:14 GMT | Chris Mellor

Hard disk drive capacity growth rates are slowing and two 2.5-inch drive capacity increases are in qualification with drive manufacturers, according to TDK.

The firm is a major hard disk drive head manufacturer and its read/write heads have to match the areal density capabilities of the media they are moving across. In its results presentation for its third fiscal 2010 quarter, it showed a chart (pdf) depicting areal density increases and timescales.

TDK 3Qfy2010 Areal Density chart

TDK product launch schedule

In the 3.5-inch drive class, 500GB/platter drives are shipping now and 640GB/platter (or thereabouts) read/write heads are in qualification with TDK's OEM customers, the drive manufacturers. It anticipates that qualification will finish in the March 2010 to October 2011 period as manufacturers start mass producing 640GB/platter drives, meaning up to 2.56TB 3.5-inch drive capacities.

Four platter 2TB SATA drives have already been announced by Hitachi Data Systems, Seagate and Western Digital. Having an extra 560GB, a 28 per cent increase will be nice, but doesn't look that dramatic when we see what TDK sees in the 2.5-inch drive area.

Here 250GB/platter drives are shipping and TDK has heads in qualification for both 320GB/platter and 375GB/platter. That would enable 640GB and 750GB twin platter 2.5-inch drives.

Got an industrial type computer at work last summer. Has an 8 GB solid state drive and a 500 GB frisbee drive. The OS (WinXP) is on the solid state drive and the apps and data live on the spinning media.

That thing is the fastest booting XP machine I’ve ever seen!

My first machine had no hard drive.

Storage was on cassette audio tapes.

Can someone explain why computers aren’t going away from sata (moving parts) hard drives and using instead RAM type (non moving part) Hard Drives?

They are.

In 2 years all high-end laptops will ship with solid state drives. Although my Windows 7 PC boots very fast I will be installing an 80Gig SSCD drive as my boot and reconfiguring the old drive as data-only.

I'll probably mess everything up first time out.

Solid state drives ARE replacing disk drives. HDDs are going the way of the CRT.

The interface for most solid state drives is still SATA.

I can't see this mattering too much, except for huge data centers. Is there anyone running out of disk space on home PCs, workstations or typical servers?

Are 1-2TB drives just too small?

I know that ours aren't anywhere near full, and 500MB+ drives (usually 2.5" in our rack-mounts) will easily keep us for a very long time.

Tandy Color Computer - 16K Extended Color Basic

Save your BASIC or Assembler program to cassette tape, again and again, just in case.

Oh, Gosh, I remember those. Code could be entered via keyboard or keypunch card decks. Storage on tapes.

My first one was actually mounted on an expansion card, in an IBM XT IIRC. Every slot had a card in it, and with the variation in the amount of space available in terms of length at each slot location, the cards could only be put in one way.

Now that was MY first hard drive. I worked in a business where the bookkeeper had the only machine that had a hard drive (there were several dual floppy machines for common use). The thing was 4MB and had it's own box and power cord!

I can remember paying $250 for a 500MB HardDrive at Frys back in the mid 90’s. Now they practically give away 4GB USB ThumbDrives.

For a long time $3-4/MB was about the going rate, so you were doing pretty good there.

Price. You can get a 1 TB spinning drive for $85, but the same thing in solid state will cost you almost $4,000. Give it time.

I upgraded from two 5.25" DSDD 360K drives, to a 10MB. Don't ask me how much that cost.

If I had only waited....

Depends on what you're storing. A/V is going to be the biggest consumers of disk space. Want to re-rip your CD collection in a lossless format? How about Hi-Def video and Dolby sound for your home theater. I can plug an external USB into a Dish ViP722 DVR and move recorded content over to it; 1~2TB will come in handy.

Any professional (or Prosumer) photogs out there shooting RAW at 15+MP are gonna eat up space real quick too.

People and technology will find a way to eat up the space.

It was the SYM-1. It had a Hex keypad and led display. 4K memory, 1Mhz 6502 cpu. It was the size of a sheet of notebook paper. It even had the holes for a 3ring binder. I hooked up a keyboard and VT100 monitor and used it to log in to the University mainframe at 300 baud. Man. I was state of the art! Or so I thought back when.

You had casettes?

We had paper tape and thought it was a huge improvement over the stone tablets we started with.

When I started coding, all we had was 0s and 1s, and sometimes we didn’t even have the 1s.

Yeah, unary with just zeros is hard. Hash marks are easier to read when you have ones.
