Some portable computers have the option of turning the screen to the angle of 180 degrees and close it with the keyboard – the result is a true tablet computer without a keyboard. These models are sometimes referred to as transformers or tablets - they can be used both as a standard portable computer and as a tablet computer. This option is very handy for reading or, for example, drawing when the keyboard is not required.

A bigger monitor is usually required for editing graphics or reviewing big-size tables, etc. However, it has to be considered that a bigger screen means a bigger size and usually also a bigger weight of the computer, besides it can be damaged more easily during opening and closing.

AnSSD, or Solid State Drive, is a modern storage device that, unlike hard disk drives (HDDs), has no moving parts and stores all information on NAND memory chips. This is why SSDs are much more reliable, as they can withstand shock, vibrations and temperature changes much better. The main advantage is the high data transfer speeds as well as the lowaccess time. Currently, SSDs equipped with a SATA 3 port deliver data transfer speeds of 500 MB/s on average. However, some drives using M.2 or PCI-Express ports have data throughputs

2000 MB/s.
