How to improve NTFS read/write speed on Ubuntu 22.04 by adjusting mount options.

Fix NTFS Read/Write Cache and Throughput on Ubuntu 22.04

On a WD HC550 drive, write speed under Windows was around 250 MB/s. On Ubuntu, read speed was acceptable (200 MB/s+), but write speed dropped to around 80 MB/s.

The fix was to adjust mount options in /etc/fstab.

After this change, read/write speed returned to around 250 MB/s+.
