Question: I currently use ntfs-3g on my mac to be able to write to NTFS-formatted drives. I have seen two commercial alternatives that boast better performance and more advanced features - [Tuxera](http://www.tuxera.com/products/tuxera-ntfs-for-mac/) (a commercial version of ntfs-3g it seems) and [Paragon](http://www.paragon-software.com/home/ntfs-mac/). 

Are these products really better? Any experiences, hard facts, benchmarks from real-world use?

Answer: 
Mixed-mode WPA2-PSK is probably good enough, as long as your passphrase is well-chosen. If you don't really need TKIP (WPA "1") anymore, consider making it WPA2-only (that is, AES-CCMP only), because there have been some attacks against TKIP recently.

MAC address filtering is a waste of time. MAC addresses are easily discovered and spoofed. Using a "hidden" SSID (a.k.a. "non-broadcast" SSID, a.k.a. "Closed Network") is also a waste of time.
You could use a penetration testing system like [BackTrack](http://www.backtrack-linux.org/ "BackTrack").
