Hello, I've been using freenas for sometime now and really love everything about it. Right now I have 4 2tb drives in a raidz configuration. I was using 8gb of ram and was getting 50-60mbs write speed. I figured I had about the minimum required amount of ram for the drives I had so I decided to upgrade to 16gb of ram. My write speeds are exactly the same more or less. This doesn't make any sense to me since everything I've read centers around ram being the single most important thing when it comes to performance with the configuration I have. My motherboard is an asus m35m1-i.
On the flip side, before settling in on freenas, I decided to try it on an older pc using a gigabyte 780g motherboard with an athlon 3 core cpu. I only had 2gb of ddr2 memory on that setup with the same 4 2tb drives. So in theory, the 2gb of ram should have been a huge bottleneck. But my write speeds were around the 120-130mbs range. So either everything I've read about the importance of ram is being exaggerated and the motherboard and cpu is far more important, or I have a serious underlying problem I don't know about. Any help would be greatly appreciated.
