If you are a gamer, developer or regular user who wants to upgrade their laptop’s or desktop’s HDD, then a SATA3 will be the perfect fit for you.
Users who own a laptop or an ultrabook with an mSATA or M.2 connector but don’t want to replace their current HDD can buy an mSATA or M.2 SSD respectively. The availability of mSATA SSDs is limited as 2 connectors have replaced mSATA connectors.
Enthusiasts and users who create and render videos in 4K resolution or perform other tasks with high disk-I/O requirement can consider an NVMe SSD provided their desktops or laptops support it.
