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 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.

Four words: Solid State Nano Memory
Hey...I got a terrabyte the other day for $100. Good enough for me! :)
Is Intel the only reliable SSD?
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 HD was 40 MB, lol.
My first machine had no hard drive.
Storage was on cassette audio tapes.
frisbee drive ?
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?
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.
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.
you had audio tape? we used teletype paper tape off a timeshare host...;)

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