Is there an optimal NTFS block size for Oracle 11G OLTP system on Windows?ideally FS block size should be equal to Oracle tablespace block size.
or at least be N times less than Oracle block size.
For example - if Oracle BS=8K then NTFS BS better to be 8K but also can be 4K or 2K.
Also both must be 1 to N times of Disk sector size. Older disks had sectors 512 bytes.
Contemporary HDDs have internal sector size 4K. Usually.
