FreeNAS Speed Problems with WD Green

[Apollo686]

I have a FreeNAS (7.1.0) running with 3 WD Green EARS drives in RAID5. I switched over to these drives from 5 1tb drives (seagate and wd). I turned head parking to 300s (5min) and using raid5 have had no problem with the 4k blocks.

So heres the problem. My HTPC is attached over gigabit ethernet and speeds are awesome. I am getting 60-100 MB/s transfer speeds wired. When I try to copy files from my wireless system I am getting 1.75 MB/s. This seems like a network issue, except with the other drives I was using I was getting fine speeds (at least enough to stream smoothly) using the same network, no changes.

Is there anything I can do settings wise to increase my wireless transfer speeds or is this a network problem? Also, has anyone setup a SSD as a cache drive on FreeNAS and seen a good improvement? I have plenty of extra SSD's if this will help with speeds.

If you have 54Mbps wireless that means about 2 or 3 MB/s of real throughput in good conditions; so you would need wired networking for those 60-100MB/s speeds. Wireless-n is up to 600Mbps so 40MB/s would be possible under good conditions i think. But you see cable is faster and can maintain that speed over longer distances.
