Before I start I just want to say that I've done a TON of research on this and have tried everything that I can find, short of getting a different controller, to resolve the write speed issues that I am seeing.
Current Rig:
OS: Windows 7 Professional 64-Bit
Case: Corsair Obsidian Series 800D
PSU: Corsair Professional Series Gold AX1200
Motherboard: GIGABYTE GA-Z97X-UD5H
CPU: Intel Core i7-4770K @4.3GHz - Cooled /w Corsair H60
RAM: Corsair Vengeance Pro 16GB
Video Card: PNY GeForce GTX 780 XLR8 OC
Primary HDDs: 2x - Samsung 840 Pro Series 512GB - Intel HardRAID 0
Secondary HDDs: 4x - WD Caviar Green 2TB
--Setup w/ Adaptec 6405 RAID Controller w/ Flash Module - Configured w/ RAID 5
So I have an Adaptec 6405 (yes I know, now, that they're immature and I SHOULD have gotten a 5 series) w/ 4 WD Green 2TB drives in a RAID 5 and the ZMM. I know a RAID 5 automatically means a performance drop, but the numbers that I'm seeing are WAY worse than I would expect.
First off, here's the controller config:
Yes, 3 of the drives are 3 Gb/s and one is 6Gb/s, but that should not be causing any major problems. You can also see that individual write cache is off for all 4 disks and enabled for the Controller itself, which is one of the first things I had found regarding performance for this kind of a setup.
Here are some results from CrystalDisk:
500MB (should be instant as it has the 512MB flash, and w/ Windows it usually is, but this is showing really bad results)
1000MB
2000MB
4000MB
Occasionally, I'll see bad performance in general in Windows when navigating through the folders etc. where Explorer has to stop and think for a bit before loading the next folder and, when copying data, the green progress bar will usually pause for a moment before continuing to copy. This problem seems to be more apparent with data amounting to 5GB or more. Anything less than that seems to do exactly as you'd expect.
Sorry for the massive 'Wall'O'Text', but I thought the code section I used for the controller config would have automatically configured a scrollbar after X lines.
Any insight, short of insults, etc., is very welcomed at this point as I'm nearly tearing my hair out. If you need any additional info let me know and I'll provide it as quickly as I can.
TIA
