In 1990 I bought a 300MB SCSI drive for my 386 tower for $1000. Am a bit confused here. If Didgets uses a 64 byte metadata record and NTFS uses a 256k metadata record, wouldn't the read times be one quarter of the time?

On a modern hard drive with 4K (4096 bytes) physical sectors, NTFS uses the full 4096 bytes for each file record segment (FRS) which is 64x as big. Ext4, a popular Linux file system, has a default inode size of 256 bytes which is only 4x the Didget record size.

On my machine with a 250GB SSD, and on another with a RAID mirror 3TB spinner, it is showing 512 bytes per sector. On an external backup 3TB USB spinner it is showing 4096. FSUTIL won't show me what is is on a mapped drive to my NAS.
