Is it possible to minimize harddrive by using any option? I’d like to buffer at least 10 MB in memory before they are written to disk.
BitComet’s cache already uses the memory before writting to the HD and it works fine. BC does not put any more stress on your HD then any other normal program. So you don’t have to worry. 
The same goes for µTorrent, just in case you’ve been reading stuff floating around the net from tards.
Look in the settings and check the cache if you want, BC works best with auto where it will use around 50 megs. B)
