Mac OS X and Linux: Now that you’re dual booting Windows on your Mac, you want to save files to your Windows partition while you’re booted up in OS X.

You can also use the previously mentioned MacFUSE to write to NTFS disks, but while mounting disks over SSH went without a hitch with MacFUSE for me, I had trouble with NTFS disks (though NTFS-3G worked perfectly). The NTFS-3G driver is a free download for Mac and Linux.
