Moreover, exFAT respects the physical reality of how Windows 10 manages removable drives. When you set the "Quick removal" policy (the default since Windows 10 version 1809), exFAT works harmoniously with write caching disabled, allowing the user to unplug the drive without explicit ejection in most scenarios—a massive usability win. NTFS, with its default "Better performance" policy, requires explicit ejection; ignoring this risks a corrupted $MFT (Master File Table).
NTFS, in contrast, is the industrial bulldozer. Designed for internal hard drives and SSDs under Windows NT, NTFS offers file permissions, encryption (EFS), disk quotas, journaling ($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." best format for usb drive windows 10
However, no format is absolute. There are two specific scenarios where exFAT is not the answer. Moreover, exFAT respects the physical reality of how
