Below is my first draft of a change to fix these problems. I would appreciate it […]

Based on my investigation of RAID reliability [1] I have determined that BTRFS [2] is the Linux storage technology that has the best potential to increase data integrity without costing a lot of money. Basically a BTRFS internal RAID-1 should offer equal or greater data protection than RAID-6. As BTRFS is so important and so […] ZDNet has an insightful article by Robin Harris predicting the demise of RAID-6 due to the probability of read errors [1]. Basically as drives get larger the probability of hitting a read error during reconstruction increases and therefore you need to have more redundancy to deal with this. He suggests that as of 2009 drives […] |
