external SSD reformat

How often is often and why as often as you are thinking? Every write action contributes to shortening an SSDs life. However, they last a lot longer than most people seem to think.

What's more important is not that you're doing it but why. Once formatted, it should not need reformatting unless something is wrong, you change to a Windows system, or you repurpose the drive.

I’m glad I asked

thank you

I have a SanDisk 2TB EXTREME PRO and I use it for editing video with my MacBook Pro . A project consumes 1.5 TB when I complete the project I thought it would be okay to reformat the SSD

I guess this is not a good idea. Thank you

If you no longer need the data on the drive just delete the data. Or, move the data to another drive. No need to reformat.
