Launching the STH RAID Calculator v1


A few weeks ago I decided that I was going to put a renewed effort into building useful tools for The first tool is relatively simple, it’s a RAID calculator that allows you to pick RAID levels then computes the resulting array capacity. Feel free to check out ServeTheHome’s RAID Calculator and give some feedback on the future direction of the tool. I do plan to have the simple Poisson distribution based MTTDL (mean time to data loss) calculations found in the MTTDL primer added shortly to the RAID Calculator, as well as explicitly add ZFS RAID levels such as RAID-Z, RAID-Z2, RAID-Z3 (for now one can use RAID 5 and RAID 6 to approximate.) One other item for the RAID Calculator is to add redundancy options such as support for Windows Home Server V1’s drive extender and Windows 8’s storage spaces in the near future. Another item we will be adding shortly to the RAID calculator is the ability for the tool to accept any drive size for all of the RAID levels.

Just disclaiming up-front, I know the RAID calculator is not perfect and probably will never be perfect, but I wanted to start getting feedback soon. Also, if anyone has any desire to build a similar tool, or has a great idea for another home server tool, feel free to let me know. I always enjoy getting feedback on what readers would like to see on the site.
