Yeah, it is pretty good for a motherboard released in 2005 (AsRock 939Dual-Sata2). The other challenge was finding an AGP card which worked well in modern Linux. The winner was a GeForce 6800XT. The 6600GT was almost OK, but 1080p video playback was skipping frames, perhaps related to the bridge chip. HD4000 series all had issues with something in Linux, e.g. choppy scrolling though files in the file manager, or scrolling issues in a PDF viewer, etc.
I had also tried some LSI MegaRAID SATA 3.0 controller, particularly because it had XP drivers, but that card had all kinds of problems on this system.
You have quite the number of drives on your system. 306 MBytes/s in RAID5 with platters is pretty impressive, especially if you are at PCIe 1.0a. What motherboard is that in?
By way of comparison, on my screenshoot you can see 4.0 TB Drive called "Adaptec Storage". That contains two ST2000DX002-2DV164 drives in stripe. These are hybrid drives, 2 TB each, and I think with 8 GB of SSD cache. With the same 10 MB sample size, 100 samples, etc, they their average read rate is only 189 MBytes/s. So I am left wondering how you can pull off 306 MB/s.
