Secure erase is useful when you need to restore factory performance to your SSD or when you want to make sure that there are no leftovers in case you want to sell it, my SSD is SLC based and I really don't worry about the wear and tear plus it doesn't support TRIM and therefore every time I want to reinstall Windows I secure erase it first and then proceed with the rest. FYI, formatting an SSD does not restore its performance, only TRIM can (for MLC based SSDs) and secure erase for both SLC and MLC. In your case, that you have an MLC based SSD, you can go ahead and format your drive without having to secure erase it, the performance difference does not justify the time you will spend doing it or the wear and tear to your NANDs. Once you have Windows installed and TRIM will kick in, you will get almost optimal performance.
