If you want to create your very own SSD, you will require an SSD Enclosure such as the Asus TUF Gaming Enclosure and also a Solid State Drive such as the 2TB Hynix Platinum SSD. The enclosure should be of sufficient mass or thickness in order to dissipate the heat which is generated by the SSD and should be able to utilize the latest transfer protocols such as USB 3.2 Gen 2 for best performance. In addition, you will need a connecting cable which will attach the enclosure to the computer and a small assembly tool as well.
