So I have this old PC, that I'm trying to max out even at the cost of damaging parts. My HDD is Hitachi HGST Deskstar NAS 4TB, current allocation unit size is 4KB, question is, will raising it to 64KB improve performance? Will I get higher Read/Write speeds or it will be just a seeking time performance boost?
I use the PC for gaming and movies, and edit a video or two, every now and then.

HDD Specs : Hitachi HGST Deskstar NAS 4TB/7200rpm/128 MB Cache/SATA 6 Gb/s
PC Specs:
MB: Gigabyte EX58-extreme
CPU: i7-970
GPU: Asus TUF-GTX1660TI-O6G
RAM: GEIL 16 GB (2 x 8 GB) 1600 MHz CL9 Dual-Chanel
PSU: Enermax 500W or 550W ( Too lazy to open case, 80+ Bronze )

PS: Size is not an issue, I barely use 800GB out of 2TB
