12TB Server HDD. WinSCP/CrushFTP copy over LAN (SFTP/AES). 15GB file to copy

Copying to SSD ~70MB/s

Copying to above HDD w/o encryption ~70MB/s

Copying to above HDD with Bitlocker ~70MB/s

Copying to above HDD with Veracrypt AES ~70MB/s ... but intil around 10GB file transfered. Then transfer drops to 7-20MB/s.

Lately I have same problem with different computer and HDD. Hard drive "hangs" and/or has transfer drop.
