Hi every one,
I have built a little NAS server and the performance is not as expected.
The components i have used are AsRock A75 motherboard, AMD A4 APU, 4Gb 1600MHz RAM, 4 Drive Back Plain, Intel Gigabyte Network Card and 4x 3TB Seagate Barracuda Hard Drives
I frist created the RAID using mdadm in RAID level 5, after doing some testing over the network and on the host I was only abel to achieve around 100MB per second read / wright.
That lead me to the conclusion that maybe RAID 5 was probably to much for the system.
So after backing up my data I deleted my RAID volume and set out to initialise raid 10.
After all the hard drives where ready I repeated the same tests, the read wright speed did increases form 100MB to 110MB per second.
I was expecting faster read speeds, I have tested all the drives individually all averaging 150MB/s +-10MB
is their some form of bottleneck in my configuration or some software issue preventing me form getting faster speeds?
Or will I have to buy a RAID card to get better performance?
