The uneducated buyer knows only "the more gigabytes the better" about hard drives, unfortunately there is a bit more to consider when selecting a excellent data storage for your needs.
Capacity. That's the gigabytes and normally "the more the better" rule works. Just keep in mind that movies take most of space, music and images take quite a bit too, but significantly less then movies. Think of how many of each are you going to keep on your laptop. If you are not going to store much media on your computer, then don't bother with capacity, for Internet and documents even the smallest hard drive would be enough. Speed. That's right, hard disc drives have speed too. normally speed is measured in revolutions per second, which basically means how fast magnet discs inside can rotate. Approved speed for laptop drives is 5400 rpm, gaming notebooks and desktops have 7200 rmp discs, fast server solutions have 10000 rmp and sometimes 15000 rpm. But this is pretty much the corporeal limit, they can not make it faster. Ssd (Solid State Disc). New technology is startling to solve the "can not make faster" question described above. These storage devices work somewhat similar to flash memory and don't have moving parts at all, which makes them about twice as fast as usual hdd and in most cases they also consume less energy. The only drawback is price per gigabyte, that's why usual capacity of such drives in laptops varies from 4 to 20 Gb. Life time. Hard drives have their life -- they born and they die some day. You can expect about 5 years of error free functioning from hard drive, after that back up becomes verily important as you can not be sure anymore how long will disc last. This does not apply to Ssd drives as they are too new and we don't know yet how long do they live. External Hard Drives. You can get a notebook computer with small hard drive (maybe Ssd drive) and get an external hard drive for your big files. External drives are pretty cheap these days, you can get a 1000 Gb for maybe 0 Canadian dollars.
