Why each option
For a 4TB LUN on a SAN for a Windows server, ReFS is the modern and recommended file system due to its advanced features, scalability, and integrity capabilities for large volumes.
ZFS is a file system primarily associated with Unix-like operating systems (e.g., FreeBSD, Linux, Solaris) and is not natively supported or recommended for Windows servers without third-party solutions.
FAT (File Allocation Table) is an older file system with significant limitations, including a maximum volume size of 2TB for FAT32 and lack of modern features like journaling or robust error checking, making it unsuitable for a 4TB LUN.
VMFS (Virtual Machine File System) is a clustered file system developed by VMware specifically for storing virtual machine files on ESXi hosts, not for direct use on a Windows server.
Resilient File System (ReFS) is Microsoft's latest file system designed for data integrity, maximum data availability, and scalability for large volumes. It supports very large volume sizes (up to 4.7 zettabytes) and is optimized for use with Storage Spaces and for high-data-integrity workloads, making it ideal for a 4TB LUN on a Windows server connected to a SAN.
