This is a crucial question. NAND flash memory (used in SSDs and USB drives) has a finite number of program/erase (P/E) cycles. A single low-level format uses up on every single cell. NAND flash memory (used in SSDs and USB

To understand low-level formatting, we need to go back to the era of magnetic hard drives (1980s–1990s). Originally, a low-level format (LLF) was the process of creating the physical structure on a bare hard disk. The drive controller would write servo patterns, sector markers, and track boundaries directly onto the magnetic platters. This was done at the factory. If an end-user attempted a low-level format on an old MFM or RLL drive, they would effectively destroy the drive's ability to function.
