2.5" Drives On the Desktop

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."

      There is no need. You can find 7200 RPM laptop drives. Just be prepared to pay even more then the 5400 drives and wait for a bit more heat. Desktop drives in laptops makes no sense. The goal has always been to improve power consumption, size/space, and heat. This is something that desktop drives don't necessarily have to strive for as they have nearly "limitless" power available, much more space available, and better heat dissipation, largely because of the extra space, but also the availability of coolers.

      Actually, that's not as true as we would like it to be. I have an acquaintance who recently has been considering replacing his file server with a standalone, single-drive NAS. In order to justify the expense to his wife, he bought a Kill-A-Watt and measured the power his current file server was using. It was using 100W, vs. the 12W of the NAS. That's a difference of 88W. However, at our current electricity rates, that amounts to a whopping $8/month savings.

      Considering that your hard drive is only consuming a few (as in, 10) watts, replacing it with a notebook drive won't save you any significant amount of money, even over the VERY long term. The advantages for notebook drives come, as others have said, in their small size and lower power consumption for notebooks.

      SRAID is the abbreviation for Software Rapid Array of Inexpensive Discs. It's the ability to use several discs to define a filesystem. There are numerous levels to RAID, some of which increase disc performance, while others increase the chance of keeping data if something bad were to happen to the disc(s).
      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.

      Heat (and relatedly, the somewhat lower power consumption) counts as the only advantage to using 2.5" drives. They cost more, hold less, and have shorter lifespans (They also make a more... "annoying" noise, IMO, though I don't know if I can fairly call them "louder"). Except for the niche markets of laptops and SFF/embedded, no one should ever even consider a 2.5" drive unless some design contstraint absolutely precludes the use of a 3.5".

I have seen many desktops and alot of servers use a laptop CD/DVD drive in them. Eventually, they will make a desktop with a motherboard similar in size to a notebook motherboard, but it will have PCI Express or some other new connector for adding peripherals. You can already purchase PC card sound cards. It's a logical progression. On Dell's site, they have a new XPS machine in the notebook section and it's really just a very small and very powerful desktop. I have also seen the Pentium M being used in desktops now. The age of tall towers is going to start to wane. There will always be a need for larger cases, but those cases will now hold much more in storage and other hardware.

    I have found notebook harddisks run hotter, they are slower, more expensive and because they are not meant for use within a tower will require some creative mounting. If you need to mount a large amount of drive space in a MicroATX, use one 600+GB drive instead of 10x60GB.

    The only conclusion they came to is that it was quieter and that there were other ways of silencing your desktop. I have a pocket 2.5" in a travel case, and it isn't very quiet. One day in the future we may see this HDD form-factor taking over the desktop market as we move towards miniturization, but IMHO the technology just doesn't seem mature enough.

And for a desktop having a 5400 rpm harddrive (as a new project) is pretty slow. 7200 rpm harddrives are very cheap now.
