How are files stored in NTFS?

Each file is stored on the HDD in one or more clusters or disk spaces of a predefined uniform size. Using NTFS, the sizes of the clusters range from 512 bytes to 64 KB. Windows NT provides a recommended default cluster size for each drive size. For example, a 4 gigabyte (GB) drive has a default cluster size of 4 KB.

Does NTFS have a File Allocation Table?

Windows-supported operating systems rely on one of two different types of file systems: File Allocation Table (FAT) or New Technology File System (NTFS). The file systems use a set of rules to control how data is stored and retrieved on a storage device.

Which filesystem is fastest?

Under Compile Bench, EXT4 was the fastest on all three drives followed by a mix of XFS and F2FS. The PostgreSQL database server ran well particularly on EXT4 and XFS while F2FS on the USB 3.0 SSD testing ran into a strange performance drop while Btrfs was still problematic from the USB storage.
