2.5" Drives On the Desktop 291
An anonymous reader points out an article on XYZ Computing exploring the use of a 2.5" notebook hard drive in a desktop computer. From the article: "The tradeoff for these qualities has always been limited capacities, high costs, and slow transfer rates, but a the recent progression in portable storage techology has changed the 2.5" drive greatly. We put the Seagate Momentus 5400.3 160GB SATA notebook drive in our test system and took it for a spin."

Many laptop manufacturers now give options for 7200 spin HDD's in laptops. I have one from Dell, it somehow runs as cool and quiet as a slower 5400

I'd say that's pretty telling.

The next generation of laptop hard disks have performance characteristics that are competitive with three generations old desktop hard disk drives. I fail to see a story. I'd be much more interested to see them compare these new 'hybrid' laptop hard drives with genuine top-of-the-line desktop drives.
And the newest hard disks aren't that loud. I just upgraded my iMac G5 with a WD Raptor (10kRPM SATA). You can definitely hear it more clearly when large files are being written or under swap conditions, but most of the time the difference in noise levels is indistinguishable -- meaning silent. And my subjective benchmarks reveal an almost 4x increase in the speed of common tasks.

"This high capacity is made possible by perpendicular recording, a technology which records data on the hard drive perpendicularly instead of longitudinally,"

Umm... Maybe you misread that. It's over an inch tall, and 4"x5.7", according to its spec sheet [hitachigst.com]. That would make it, by necessity, a 3.5" form-factor hard disk. It is nice, though. Now I just have to get a machine that can use SAS drives well, and save up a lot of money. I've got a 15kRPM Fujitsu hard disk around here somewhere that a customer gave me, but I never got around to shelling out the money for a Ultra320 controller so I could use it. C'est la vie.

I think the news here is about faster 2.5" drives, not the possibility to put a 2.5" drive in a desktop. As that has been done for decades.

There are two forms - Software and Hardware RAID. Software RAID is configured by the operating system, whereas Hardware RAID is a standalone piece of hardware that holds the discs and provides configuration utilities on the box itself.
You can read up on RAID (Software and Hardware) over at Wikipedia [wikipedia.org]

This case plus a 250GB 7200 3.5" PATA drive cost me $170, less than a 2.5" 120GB drive. And I got USB and Firewire hubs built in as well.

Of course now you don't have a 30 pound beast with a 5 inch screen. But it is the exact same concept.

Meanwhile, a desktop can be upgraded in $100 increments. None of these increments are particularly painful. No need to replace a display until it breaks (rare) or becomes obsolete (rare). Same for keyboard, mouse, and arguably HDD.

Seems to disagree with you. There are no 15,000 RPM 2.5" drives, and only a couple of 10K 2.5" drives on the market right now

This page charts the annual improvement of price per capacity of hard disks (amongst other things): http://www.mattscomputertrends.com/harddrives.htm
This page does the same thing for flash: http://www.mattscomputertrends.com/flashmemory.ht
Here is a key quote: "The improvement rate for flash for the last three years comes in at 109% a year whereas for hard disks over the same period the figure is only 35%."
