A Linux technician needs to provision a new 4 TB internal drive on Ubuntu 22.04 used for video editing. The drive must store single files larger than 4 GB, reduce fragmentation through extent-based allocation, and be fully supported by the Linux kernel without extra drivers. Which filesystem should the technician choose?
ext4 is the default Linux filesystem and introduces extent-based allocation, which lowers fragmentation and improves performance. It supports volumes up to 1 exabyte and individual files well beyond 4 GB, making it suitable for large video files. FAT32 cannot hold files larger than 4 GB, NTFS requires third-party driver support for full read-write capability on Linux, and Microsoft ReFS is not supported by the Linux kernel at all. Therefore, ext4 best satisfies all stated requirements.
