Windows File Systems

Описание: This technical analysis clarifies the critical distinctions between Windows file system architectures, addressing the common confusion regarding when to utilize NTFS, FAT32, exFAT, or the modern ReFS. Selecting the incorrect file system during drive initialization can lead to cross-platform incompatibility, file size limitations, or silent data corruption. We examine the engineering specifications of each standard to determine the optimal configuration for boot drives, external media, and long-term storage arrays.
Technical Details and Architecture
The discussion begins with NTFS (New Technology File System), the mandatory standard for Windows boot drives. We analyze its journaling capabilities, Access Control Lists (ACLs), and metadata management that ensure OS stability and security. The video then addresses the legacy constraints of FAT32, specifically its 32-bit addressing limit which caps file sizes at 4GB, and contrasts this with exFAT, the industry standard for flash storage that eliminates these overheads while maintaining compatibility across Windows, macOS, and Linux.
Finally, we explore ReFS (Resilient File System), a modern architecture designed for data integrity. We detail how ReFS utilizes integrity streams to proactively detect and repair "Bit Rot" (silent data corruption) on mirrored storage spaces. Additionally, we evaluate the role of ReFS in high-performance scenarios, including Dev Drives for faster code compilation and future integration with DirectStorage for gaming.
Key Technical Points
File System Hierarchy: Understanding how data is indexed and retrieved at the block level.
NTFS Specifications: Analysis of journaling, fault tolerance, and permission structures.
Legacy vs. Modern Transfer: The architectural limitations of FAT32 vs. the scalability of exFAT.
Data Integrity: How ReFS combats Bit Rot through automatic checksum verification.
Performance Tiers: Utilizing Dev Drives and ReFS for virtualization and compiled languages.
Deployment Guide: A definitive decision matrix for formatting system drives, USBs, and backup HDDs.
