I am currently teaching myself the ins and outs of FreeNAS. What I have setup it not production yet.
It is mostly recycled hardware, so it is pretty wrong compared to what is a "good idea". Once I am comfortable with FreeNAS something with ECC memory is likely.
AMD Athlon X2 240 (dual core 2.8Ghz)
2x4GB 1600 DDR3 NON-ECC
MSI 890 GD 70 (7 onboard sata)
2x Realtek NIC's (awesome I know, Intel 4x on the way)
5x 1Tb WD Blues
My desktop:
AMD FX-8320
16GB DDR3
Samsung 840 EVO
WD Green 3TB
Realtek NIC
Network is Gigabit.
I first setup 4x drives in a RAIDZ2. CIFS share.
Transferring 8Gb of data from my desktop's SSD to the Freenas copied at a constant rate of ~56MB/s. (according to my desktop)
Copying from the WD Green on my desktop to the NAS also copied at the same rate.
I killed the RAID, added the fifth drive, rebuilt the same config but with 5 drives, and tried again. No change in transfer speed. Copying to the NAS was ~56MB/s.
Copying from the NAS to my desktop SSD was ~45MB/s.
Why would reading from the NAS be slower than writing?
Why would I see no change in speed with the extra drive? The performance monitor during transfers doesn't show the cpu getting pegged at all. Maybe the realtek NIC's?
