A portable M.2 SSD is generally better than a USB stick for several reasons. M.2 SSDs are faster and have higher storage capacities compared to USB sticks. They also have better durability and reliability, making them more suitable for frequent use and data transfer. Additionally, M.2 SSDs are designed for more intensive tasks such as gaming, video editing, and running large applications, making them a better choice for users who require high performance and storage capacity. **

Formatting is better than quick formatting for a USB stick because it thoroughly erases all the data on the drive and checks for any errors, ensuring a clean slate for new data. Quick formatting, on the other hand, simply deletes the file allocation table and marks the space as available for new data, which can lead to potential data recovery issues and errors in the future. Therefore, for a more reliable and secure process, it is recommended to perform a full formatting of the USB stick. **
