MacPro 4,1
12 Gig memory
Rocket Raid 2722
4 drives in RAID5 setup - directly attached to the RocketRadi2722 card.
Tuxera Version 2014
(Paragon version whatever was latest on 2/23/15)

Aja Speed test:
Running Aja disk test - 2048x1556 10 bit, 16 gig file test

Windows 7: 320 MBs write / 350 MBs read
Mac with Raid5 formatted in HFS+: 200MBs write / 240 MBs read
Mac with Raid5 formatted in NTFS - Paragon 200MBs write / 238 MBs read
Mac with Raid5 formatted in NTFS - Tuxera: 85MBs write / 87 MBs read

Any ideas or suggestions how to fix? (I already purchases Tuxera) Paragon is running in 15 Day trial mode.

Thanks

PS. Tuxera was running without Paragon Installed. Also the system was newly installed with only Myricom 10 gig E drivers installed.
