Hey Guys, A while ago when I did a Disk Speed Test, I was getting 260-270 MB/s. After recently realising that my DaVinci Resolve performance dropped slightly, I decided to do another Disk Speed Test of which I then found out disk performance dropped to 150-160 MB/s. I then decided to delete some unnecessary files from my RAID to increase available space, thinking performance could improve as a result. However, I was still getting 150-160MB/s.. I checked my RAID Utility and it still has a green light and says 'Good' on the two volumes I have. The last time the Battery conditioned itself was about two and a half months ago. What else can I do to get back to 260-270 MB/s again? Also... and whats strange... I did another test on my Mac HD volume at RAID5 and was getting almost 300mbs as opposed to my other volume (currently 150mbs. 260mbs before....). Im really confused... I have x4 WD black caviar HDs (1TB each) and Apple RAID card. Any help is appreciated Thanks. Alex.
