[QUOTE="moab, post: 502002, member: 73157"] How about upgrading your small OS drive for SSD? I use a patriot 32GB for OS and apps. Bullet proof and fast. Here is my 2c on RAID. I compared running the 500GB alone with 2x500GB RAID 0 using ICH on the mummy board. The performance improvement was linear. i.e. 2 drives ran twice as fast as 1 drive etc. Here are the stats for my system: [URL="https://forum.team-mediaportal.com/general-62/best-nas-solution-45568/"]https://forum.team-mediaportal.com/general-62/best-nas-solution-45568/[/URL] I have 1 x Seagate 1.5TB Drive and like it. It is quicker than my 3 x 500GB drives in RAID0. Out of interest could you run Roadkils Disk Speed and post the results. I would be interested on the stats. I have used a lot of RAID systems and here is my thinking. Commercial RAID has more fault tolerance/features than consumer RAID. e.g. commercial RAID card stores a copy of the RAID configuration on the drives as well in the RAID controllers NVRAM which is powered by battery on the RAID card. If either RAID config gets corrupted then you can recover from the NVRAM or the Drive copy depending which one went bad. RAID5 is commonly used in servers for economy and redundancy. RAID 10 (aka RAID 0 + 1) is optimal for performance and redundancy but is expensive requiring 1 redundant drive for each good one (minimum of 4 drives). With your 12 drives you might want to consider RAID 10 with a commercial grade RAID card. The issue with OS RAID is that your CPU bears 100% of the processing for the RAID. This CPU load increases with the number of disks. Using a RAID card offloads the processing burden from the CPU and gives you much better error recovery and fault tolerance. Personally I use ICH RAID 0 because it is bargain basement. I have not had any problems with it. [/QUOTE]
