WebThe sector size is a boat. You are just making it 4x the size at the cost of space available. For what you are doing, that's fine. Large file storage (filling up the 4096 byte space) works well. Spinning disks might be happier. For SSD's, it's a wash. Small files, random I/O, can hit 512 byte as fast as 4096 bytes, it isn't any kind of improvement. WebThe newfs utility will use a block size of 32768 bytes, a fragment size of 4096 bytes and the largest possible number of blocks per cylinders group. These values tend to produce …
