Hay Guys,

I own a file hosting service and i am kind of not sure what to do with Raid.
My server Configuration is as follow:

HP DL180
Dual Xeon E5620
24 GB ECC DDR3 RAM
12 X 2 TB 7.2 Enterprise Drives
10Gbps Port Speed

No i have Raid Configured to RAID5, and it is a disaster.
I am serving about 30,000 Downloads per day from this server, about 15TB per day.

My current read speed is as follow:

Code:
:~# sudo hdparm -t /dev/sda

/dev/sda:
 Timing buffered disk reads: 232 MB in  3.18 seconds =  73.01 MB/sec
I don't know what Raid Configuration should i go with, keep in mind that i need as much space as i can.

Thanks in advance.
