Raid Backup for HTPC
Hello,
My father in law is concidering building a HTPC after seeing mine and is wondering if installing raid drives in a mirror configuration to back up movies, music and pictures would cause any kind of speed issue when using SageTV. I am not currently using raid so i can't answer the question for him. If anyone knows or has a HTPC with this confiuration could you please let me know. Thanks in advance. |

No, RAID is not backup, if it's important enough to backup, ie, unreplacable, precious, familly movie type stuff, you want it backed up onto something not connected to the computer.
Now that said, you were asking about performance. Don't do any form of RAID for a performance boost, that's basically a myth. RAID should only be used in specific circumstances: RAID-0 - For uses where high sequential transfer rate is crucial, and reduncancy isn't necessary, like for video editing. RAID-1 - For applications where 100% uptime is needed (not for "backup") RAID-5 - For applications where huge storage space is needed, redundancy is desired (to mitigate the increased risk of data loss from hardware failures), eg Media Servers |

More or less agree. Depending on controller mirrored drives can be faster on reads accessing both drives at once compared to standalone. On writes mirrored drives are basically the same speed as standalone, just writing to both simultaneously.

FWIW on the speed thing, my 8x250GB RAID-5 array does about 90MB/sec average read and somewhere about 40MB/sec average write.
