The OCZ Agility 4 is a relatively old SSD and has been included in the group test as a reference. In terms of overall speed the Agility 4 lags the current ten market leaders by an average of around 30%, considering that the Agility 4 is only 16 months old this highlights just how quickly the SSD market has evolved over the last two years. It's probably not worth upgrading for the sake of more speed unless you have a specific use case that demands it but if you are looking for a speed upgrade, you will gain up to around 50% by going for the Samsung 840 Pro or the OCZ Vector. [Sep '13 SSDrivePro]
