I'm inclined to blame the 3ware. I never used one that impressed me in the slightest, though 5mbps certainly suggests a deeper issue.
In any case, I'd consider snagging a Dell PERC6 or PERC H700 off ebay. I just did a series of RAID5 and RAID6 tests on a bench PERC6 and a used PERC H700 I got off ebay for $100. Both of these cards are based on slightly altered LSI MegaRAID adapters and even support using LSI's management software, though note that the PERC6 does not support physical disks > 2TB. All tests performed using 8x2TB Toshiba HDDs. CrystalDiskMark sequential using a 4000MB test file: PERC6 RAID5: 791MB/s read, 485MB/s write PERC6 RAID6: 671MB/s read, 398MB/s write H700 RAID5: 1086MB/s read, 1015MB/s write *this is effectively the theoretical peak potential of the underlying HDDs* H700 RAID6: 937MB/s read, 704MB/s write Disks are also important. Either buy RAID-rated disks, or Toshiba's DT01ACA series. Expect everything else to cause problems.

I have been working on retiring an old freenas box so I built a nice server with spare parts running freenas 9.xxx x64. I have a hardware raid array (3x3TB raid 5) on a 3ware 12 port contoller. The interface is way different than what I'm used to but I can deal with that. The transfer speeds are horrible though and pause about every 20 seconds. I'm only averaging 5 mbps compared to 55 MB/s on my drobo5n. This is actually a backup for my drobo5n that will get powered on about 1x every 2 mos to update any new files, etc. I've heard nas4free is a little more solid compared to newer versions of freenas. Never tried it though. Suggestions? Write caching is turned on - still slow as hell lopaka
