Mac OS X comes with an NTFS driver but it does not support writing to NTFS volumes out-of-the box. The fix is here. We are pleased to announce the immediate availability of Tuxera NTFS for Mac Trial. You can download it here. Please note that this is a release candidate version and the final one will be available before the 15-day trial period is over.

After installation, Tuxera NTFS becomes visible in your System Preferences.

There are many options you can play with. See the manual for explanations.
This is a release candidate version and a major upgrade from our previous open source NTFS-3G for Mac. Performance has been significantly improved along with other enhancements. We are pretty sure this is the fastest read/write NTFS driver you can have for Mac. We have successfully tested it on Tiger, Leopard and Snow Leopard. Please send us any issues you find and we will fix them before the final release is out and available for purchase.
What will be the cost for the final version?
Hi!
Then I tried Tuxera, and I can only say it rocks. I’ve tried an intensive overnight 4 BluRay x264 HD Movie .torrents from high-speed private trackers downloads with no problems and low CPU utilization.
I’ve been delaying the installation of NTFS support in Snow Leopard for sometime, although I used Paragorn in Leopard.
I couldn’t wait anymore, so I tried NTFS-3G.. high cpu consumption
I guess you wouldn’t find no one to give your 3 free accounts, because I didn’t find any bug with intensive use on a MacBook Air and an External Lacie Little Disk over USB. If that happens, give me one
I’ve twitted to the world! Tuxera rocks

Keep the good work!

Although, there’s some *some* CPU consumption if I have the Finder opened, in the List View, with “Calculate All Sizes” checked in View Options.
Is it a bug, or something inherent to the USB interface? Couldn’t test it with a SATA internal drive.
So .. how do I know that “”performance has been significantly improved” and that I want the “enhancements.”? Could you provide benchmarks and a comparison sheet of what benefits Tuxera NTFS has over the free NTFS-3G. Until you do I’ll keep using the free version.
Nuno Liça Pinto:
Hi,
You cannot expect 0% CPU consumption. With kernel drivers this is hidden inside the big kernel_task process, but of course any file system driver will have to do some CPU work when traversing directory hierarchies, as is the case when you check the ‘Calculate all sizes’ option.
Thanks for the feedback.

Hi,
You can of course try it out for free to determine if it fits your needs. The trial period is 15 days, and during this period it will work with all features enabled.
But you’re right of course, we should have some marketing material with benchmarks where we compare this product to other ‘competing’ solutions. It’s on my todo list.
