Progress Finished Question

Since this is SSD you can increase the buffer size. For example 10M.
Also because of that buffer, you could know exactly how many bytes are copied. You can do some math instead calling os.stat in every iteration.

Or you can use tqdm.
Something like this:

import os
import tqdm

src = './source/big_file.big'
dest = './path/big_file.big'

f_size = os.stats('./source/big_file.big').st_size
buff = 10485760 # 1024**2 * 10 = 10M

num_chunks = f_size // buff + 1

with open(src, 'rb') as src_f, open(dest, 'wb') as dest_f:
    try:
        for _ in tqdm(range(num_chunks)):
            chunk = src_f.read(buff)
            dest_f.write(chunk)
    except IOError as e:
        print(e)
    finally:
        print(f'Done! Copied {f_size} bytes.')

It will give you nice progress bar.

I didn't tested the script.
