This is great news. Let's push away from 3.5" drives and make 2.5" mainstream for the desktop environment. Not only do the 2.5" drives use less power, they also generate less heat and noise, not to mention they use less enclosure real estate. Plus, they’re normally manufactured as portable devices, which makes them more robust.

There has been a silent push to this very thing for a few years. Hard drive storage -- using 3.5-inch hard drives -- is probably the biggest sore point in evolving Small Form Factor desktops.
My thoughts on this have been that implementing RAID-1 with a pair of 60 GB, 80 GB, or (now) 120 GB 2.5-inch hard drives and incorporating advanced read-ahead performance features -- so that the user actually benefits from the RAID-1 with more than its resilient features -- would be the best way to approach using the 2.5-inch hard drive in a desktop.
Unfortunately, the MTBF rating is not quite there yet for the 2.5-inchers when comparing them to current 3.5-inch hard drives.

LunarMist said:Awesome - just what I really need!What do you all think about realistic availability? Will other HD manufacturers have 120GB notebook drives available for mortals by the end of Q2?
Maybe Seagate. There are several players in the 2.5" market now, and hopefully the competition will help spurn the advancement in technology and help all manufacturers to be relatively close with capacity points. I am interested in seeing how this market is in Q4.
I can't wait for Q4 2005, only July 31. The 100GB drives are too small for comfort since they hold less than 6000 frames in a PSD or around 5000 frames in a notebook with a few applications installed. In a PSD the 5400.2s have good battery life but poor performance for some reason.

Maybe you should get a laptop that can support two HDDs. For my Thinkpad T23, I can buy a "ThinkPad Second HDD Adapter for Ultrabay 2000" for $45. This is the bay that takes either a floppy or optical drive without an adapter.

1. If the notebook fails, install the drives in another or in a desktop. Now, if you're talking the notebook HD fails, well, that's what backups are for.
2. No mention of spindle speed in the Computerworld article. I'm too lazy to look it up so I'm assuming 5400 RPM.

Since Seagate is the current areal storage density darling, it will probably be them, and I believe it's their turn to announce something new for the 2.5-inch arena since Hitachi did it last.Buck said:
Maxtor and Toshiba could be thought of as the dark horses in the 120 GB race to announce next.

Perhaps an external FW and/or USB2 drive, then? I seem to be peculiarly keen on annoying you with ideas you've already thought of.LunarMist said:
Yup. Only Hitachi makes faster drives. I wish the other guys would too. Prices would come down then.Fushigi said:
Maxtor in a notebook? Gee, no thanks.Explorer said:

Get a notebook with a DVD burner, dual-layer if you can afford the media. Then carry a handful of blank disks. Not much added bulk that way. Or, as mubs says, an external drive. An 80+GB notebook drive in a USB2 enclosure shouldn't require a separate power adapter. Coupled with a short USB2 cable, bulk should be easy enough to manage. Speed shouldn't be much of a concern.
I assume your images don't compress well. If they did I'd say store them in a OS-compressed folder or a zip/rar file as well to maximize your storage.

I spent a fair amount of time on risk analysis when first switching to digital. The flow chart and risk matrix are misplaced somewhere. I should probably start a separate thread.
Anyway, I have two each of 60, 80, and 100GB 2.5" drives. One of the 100GB drives is in the notebook. It would be nice to replace the smaller drives with fewer 120GB drives for simplification.

Good news. Actually, my notebook is the only system I own where space is even an issue. In a desktop system, yuo just add extra drives as needed. In a notebook, it's difficult. Befre too long I'm going to be reduced to carrying an external drive.
BTW: which is better for this, USB2 or Firewire? The laptop has both. Also, both USB slots are used (external mouse and keyboard), so I'm hoping that the best answer is Firewire.

For notebooks this is good news, but I want more. Specificly, I want 2.5" drives to perform at the same or faster level as 3.5's so that they can be considered potential replacements for desktop systems. The current crop of 2.5's just are not satisfying the needs of the desktop market and that would be my goal.
I understand that a 2.5" drive will never produce an STR faster than a 3.5 at the same RPM speed and that total storage will never be as high because of the amount of surface area. However, why can't 2.5's have faster seeks and why can't 2.5's actually have faster RPM's. Smaller sized means that heads don't need to travel as far and the forces involved in high RPM's are signifigently diminished. Most consumers don't need the total capacity that 3.5" already supply so the shrink to 2.5" will not harm them and those that do can still use the 3.5's. My point is that the same type of benefits that resulted from the move between 5 1/2" to 3.5" can be gained through the move to 2.5" or even smaller.

Firewire it is then. I'll get one of those dual-mode enclosures so that I can plug the same drive into normal systems if I need to.
Can you get enclosures that run off built-in batteries? Or will I need to carry a mains power adaptor unit, and rely on my 12V car inverter?

It would need to be a very small bicycle.

The difference in performenace for notebook drives is not hat gerat. I perfer a self-poweered USB 2/FW 2.5" enclosure, using the USB 2for travel (notebooko) and firWire on eth desktop system. If you ned a bettery powedered enclosuer, then it makes much more sense to use a PSD. At lleast one PSD is needed to mitigate risk anyway, assuming thsi is a digital photo project.

I might conclude that for a *non-mainstream* Small Form Factor desktop, one would have to consider going with a 2.5-inch "enterprise" SAS hard drive -- preferably using a mobo with an embedded SAS controller or SAS RAID. A Small Form Factor desktop with a 2, 3, or 4-slot SCA drive bay for 2.5-inch SAS / SATA2 drives would be a killer.
