June 18, 201016 yr I just setup a new unRAID server and I'm getting some odd performance degradation when using shares HW setup: AMD Athlon LE-1620 (2.4GHz) 2GB DDR2 Supermicro AOC-SASLP-MV8 Biostar A760 M2+ 2x icy dock 4 in 3 all connected to the supermicro card 3x Samsung F3 1TB 7200 (1x cache, 2x data) unRAID Basic Connected to 3com gigabit switch So, when writing to the unRAID server from my win7 machine using shares disk1 write speeds are ~9-10MBytes/s and disk2 write speeds ~27-35MB/sec If I write the unRAID server not using shares both drives perform at the expected speed of ~27-35MB/sec. Any idea what's going on when using shares?
June 18, 201016 yr Author sonofa!! It looks like my parity drive just died. Started w/ click o death for a few minutes and now it's not even recognized. Back to newegg it goes!
June 20, 201016 yr Author So I've been running now w/o the bad parity drive and transfer speeds yesterday were great (Was getting > 40MB/sec)... now tonight the server is slowing down to 5-10MB / sec.

June 25, 201016 yr Are you running the system as normal without a parity drive. I hate it when my wife states the obvious to me, but the Boy Scout in me feels the need to point out... You are at risk of losing data. If another drive fails, anything on the drive will be lost. Sorry
June 30, 201016 yr Author Hey guys, Yes I was running w/o a parity drive for a day or 2 before I could make a run down to microcenter to pick some more drives. My new configuration is 1.5TB parity, 2x 1TB data (btw, the replacement samsung drive from newegg came today, w00t! +1TB ). So besides the bad parity drive, I think my problem has to do with Windows7 64-bit and copying full directories of data. If I copy over a single 1GB VOB file the speeds are great, consistently. If I select to copy an entire directory, in my case a ripped DVD, everything slows to a crawl. My Windows 2003 server does not seem to have this problem copying data to the unRAID box. I'm currently using TeraCopy to copy files to the unRAID server from the Win7 machine now, and its been working great.
