questions regarding Journalling-FSes and w-cache reordering
Quoted 2 lines
I'd like to build a reliable ~1 TB RAID 5 from IDE drives. I will gladly give up performance for high reliability and low cost.
Most ATA-RAIDs disable write-caching, and that's not really a performance
-disadvantage with a decent drive-scheduler (afaik most OSes implement a cyclical-scan and not elevator-schedulers) when the HD has a linear mapping; and today's ATA-HDs all have linear mappings. Only with back-to-back writes can cause the HD to have a lap of honour.
