We run all NTFS drives here, for a number of reasons.

• On the fly encryption
• Superior error recovery
• Flexible partition options (striping, software raid, on the dynamic linking)
• Superior security, the access bits and information is inherent in the NFTS format

There is no way I would run a mission critical system (and I consider my personal box mission critical) under FAT32... I use the security procedures to much to take the chance.

BTW - I haven't noticed a speed difference.
