Hi, Has anyone of you made some experience with software raid (raid 1, mirroring 2 disks)?
Our workload is rather read based at the moment (Commit Log directory only grows by 128MB every 2-3 minutes), while the second hd is under high load due to the read requests to our cassandra cluster. I was thinking about putting both the commit log and the data directory on a software raid partition spanning over the two disks. Would this increase the general read performance? In theory I could get twice the read performance, but I don't know how the commit log will influence the read performance on both disks? Thanks, Thibaut
