When copying large files or testing writespeed with dd
, the max writespeed I can get is about 12-15MB/s on drives using the NTFS filesystem. I tested multiple drives (all connected using SATA) which all got writespeeds of 100MB/s+ on Windows or when formatted with ext4, so it's not an alignment or drive issue.

AMD dual core processor (2.2 GHz)

(Ubuntu default version) and 2013.1.13AR.2
How can I fix the writespeed?
