Download/write speed very slow

[Enigmach]

Update: Currently obtaining downloadspeeds of 1.1 MB/s (which is my max) with NZBGet, a class 10 SD-card and a 2TB NTFS disk. I'll check later how it runs if I add sickbeard and couchpotato, but it seem that the 300 KBytes you get with your NTFS disk is not necessarily a CPU limitation.

Edit: It seems that I had directed it to a wrong folder, so the 1.1 MB/s was on my SD-card. Currently getting ~375 - 435 KB/s, so I'll be looking for a solution as well
