Talking about IT evolution!

If you are having problems with your memory storage space at home when it comes to your PC , you can always choose to get a portable hard disk!
Now..the advantages are that they are found in small sisez and don`t need much space. Of course if you are looking to save data over 1000 Gb you probably won`t find a small hdd, the portable version being only at a max of 100 Gb! If you have more than that...well..you can always get 2. Another advantage is that they last longer than any dvd or cd! Disavantages...well...like I said...they are only found at about a max of memory of 100 Gb!
Of course as Hard disks performance grows, so does the speed of the data transfered..and here we introduce USB 2.0, bluetooth, data cables and wireless! These may not be something new for most of you, but these methods are improved daily, in the try to get the perfect speed in data transfer..and they don`t even require electricity...working on the computers energy!
