I am currently using the free NTFS-3G to access my NTFS drive from the Mac. It seems pretty stable (except once in the very beginning, it locked up the Mac and corrupted my NTFS drive, which I then fixed with chkdsk from a PC).
However, speed is NOT one of its virtues. In fact, it's painfully slow
In addition, there is now an unsupported native solution with the snow leopard.
Can folks here share their experiences. Is the native solution stable enough to be used for daily work? Should I just go with Paragon?
