For the modern Windows 10 user:
NTFS is ideal if you only use Windows PCs. It offers advanced features like file encryption, permissions, and better reliability through journaling. best format for usb drive windows 10
NTFS, in contrast, is the industrial bulldozer. Designed for internal hard drives and SSDs under Windows NT, NTFS offers file permissions, encryption (EFS), disk quotas, journaling ($LogFile), and support for files larger than 4 PB. On the surface, this seems superior. Yet for a USB flash drive , NTFS is architectural overkill. The fatal flaw is : NTFS assumes a spinning disk or an SSD with advanced controllers. It frequently writes to its metadata and journal, even for small file changes. On a low-cost USB flash drive (which has limited write cycles and often lacks a DRAM cache), this causes sluggish performance, especially for small files, and accelerates wear. Worse, Windows 10 does not safely "optimize for removal" with NTFS by default; it often caches writes aggressively, increasing the risk of corruption if the user pulls the drive without using "Safely Remove Hardware."

It is "cleaner" for flash storage because it doesn't have the heavy "journaling" of NTFS that can wear out flash memory faster. Use NTFS if: The drive will only ever be used on Windows computers and you need advanced features like file encryption or compression. It is also the required format for creating a Windows 10 installation/recovery drive. Use FAT32 if: You are using a small drive (under 32GB) or need to plug it into older equipment like a car head unit, printer, or older digital cameras that may not recognize newer formats.
