Or use: This is also why 4 KB cluster size is so important to SSD performance and, as you’ll see, NTFS has advantages over the other file systems. This was one of the shortcomings of FAT16, which could use 64k clusters to handle a 2 GiB disk, but when storing thousands of files, wasted an average of 32 KiB per file, which adds up to quite a bit. Click OK to close this format window, 1 - A lot of space is wasted by using NTFS with 64KB cluster size, specially if you have small files. If a 2kb file is written to this cluster, it only .

Microsoft recommend this for SQL server and virtual machines as well. The filesystem needs to keep track of which clusters are used for each files, so a 16GiB video file would have 4194304 cluster entries in the file table. It is optimal to match the block size to the allocation patterns of the workload that is using the disk. Using a smaller.
