With the release of ntfs-3g v1.328 (March 28, 2007) Linux finally has stable read/write support for the Windows native NTFS filesystem. ntfs-3g has been extensively tested and there was no file corruption or inconsistencies. Most POSIX file system operations are supported, with the exception of full file ownership and access right support.
ntfs-3g is 20-50x faster than the commercial Paragon NTFS driver. Curiously, Captive NTFS, which uses the native Windows NTFS drivers, fails all benchmarks with file loss.
ntfs-3g is still unoptimised and further speed increases are likely. It does not yet support compressed or encrypted files, but that is on the way.
Binary builds are available for most ofthe mainline distros or you can build it yourself.
