Weird compression idea... Probably dumb but...

just post the source code.

I can write a program that writes 4 TB in a few lines of code, doesn't mean it produces anything useful.

 

$h = fopen('file.txt','w');

$buffer = str_pad(' ',1048576,' ');

for ($i=0;$i<4000;$i++) { fwrite($h,$buffer); }

fclose($h);

 

from random import seed
from random import randint
z = 0
srtstrlen = 10000000000000 # or 2500000000 for 1 GB
seed(int(z))
srtstr = ""
for num in range(int(srtstrlen)):
    value = randint(0, 9)
    srtstr = str(srtstr + str(value))
Filename = "4TB.txt"
OpenFile = open(Filename, "wb")
Data = int(srtstr).to_bytes((int(srtstr).bit_length() + 7) // 8, byteorder="big")
OpenFile.write(Data)
OpenFile.close()

Also this is not zero data as it has been calculated by the compressor.

This is a lot faster with 40KB parts, Also new progress percentage:

from random import seed
from random import randint
z = 0
srtstrlen = 100000
seed(int(z))
srtstr = ""
srtstrint = 0
for num in range(int(srtstrlen)):
    value = randint(0, 9)
    srtstr = str(srtstr + str(value))
    srtstrint += 1
    print(str(int(srtstrint / srtstrlen * 100)) + "% Complete.", end="\r")
Filename = "40KB.txt"
OpenFile = open(Filename, "wb")
Data = int(srtstr).to_bytes((int(srtstr).bit_length() + 7) // 8, byteorder="big")
OpenFile.write(Data)
OpenFile.close()

So you're just writing random data to a file.  What's the point of this?   It's not a compressor, it's not a decompressor, it's nothing useful. 

If you're aiming for highest speed, aim for multiples of 512 bytes and 4096 bytes ... common sector sizes, so go for 32768 bytes or 65536 bytes or 1024 x 512 bytes = 524288 bytes.

It was random in this case to show that it didn't create zero data.

Edit: randint when given a specific seed will always make the same number, similar to a minecraft seed always making the same world. Then I use the original string length of the bytes converted to numbers to know where to stop creating "Random" Data.
