120GB-$150
60GB-$100
20GB-$60--->used and refurbished
If you ask me, these prices are outrageous. You can get a 500GB external hard drive for a PC for like $100! And the 60GB should be like $75 because the 60GB is half of the 120GB, so why isn't the price half!!! You can get them for a lot cheaper if they are used. I think the 120GB is $100 used. But anyway there's the prices that you asked for.
A XBOX360 costs about $190.00
$300
It $50 for a full year
Around $25.
30or20dollars
One can find cheap portable hard drives on online shops like Amazon or eBay. Just look for regular hard drives instead of flash drives, as these are more recent and cost much more then classic hard drives.
60.oo
This depends on how much money you are willing to spend on an external hard drive. Some external hard drives can have storage of 500 GB, or even up to 1 TB.
i would have to say around 300$ at gamestop.com or the store gamestop
Umm... You can't buy a gigabyte. You have to buy a extra hard drive
Laptop hard drives are very similar to desktop hard drives, indeed they work in exactly the same way and even use the same interfaces. However laptop hard drives are designed to be much smaller (2 inches as opposed to 3.5) and draw less power than desktop hard drives. As a result laptop hard drives are usually much slower in terms of data transfer and have much smaller storage capacity than a desktop hard drive of the same year manufacture. With an adapter it is possible to use a laptop hard drive in a desktop computer, and if mounted externally it is also possible to use a desktop hard drive on a laptop.
Yes. SSDs (Solid State Drives) are still much more expensive per gigabyte than magnetic hard drives, so they are still uncommon in desktops and mainstream laptops.
