It’s now more affordable than ever to purchase a large capacity solid state drive to upgrade an existing PC or to install a new one. Today, we are going to test the latest OCZ Vertex 4 256 GB SSD to see how it fares against the competition.

Large capacity SSDs such as the Vertex 4 256 GB are ideal for upgrading laptops, as they will provide enough storage space to fulfill the needs of most users. Desktop PC users can usually combine a smaller capacity SSD with a hard drive to provide extra storage space for media files if required. This option can often be cheaper, so it is worth looking into for desktop PC users.
