NAS104 Raid decision? Xraid vs Raid 10 etc #24296869
I just got a NAS 104 and installed 4 3TB Western Digital Red disks. Since I bought all my drives I don't really plan to upgrade or mess with the drives in the near future. When I powered up and ...
RAID-10 has the same disk space result as RAID-6, but does not offer the same protection benefits. It is similar to dual raid-1, in that it protects against some combinations of 2 disk failures but not all.
There's a performance review here: http://www.smallnetbuilder.com/nas/nas- ... l=&start=1 RAID-1, RAID-5, RAID-10, JBOD all came in ~80 MB/sec read. RAID-1, RAID-10, JBOD all came in ~50 MB/sec write. RAID-5 was slightly slower (~40 MB/sec write). They didn't test RAID-6, and this was done on very old firmware (6.0.5). So results are probably different now.
If you have the time/interest, you could try some or all of these combinations and benchmark them with NAStester (http://www.808.dk/?code-csharp-nas-performance). If you do this, I'd suggest turning off antivirus protection and snapshots. I'm sure there are folks here who'd be interested in seeing your results.
In any event, I'd rather have a 9 TB volume and 40 MB/s write speeds than a 6 TB volume and 50 MB/s write speeds. So with this NAS I don't think RAID-10 is a good balance.
If you want to focus on ease of recovery, then dual-RAID-1 is better than RAID-10, since you can read the data using a linux boot CD (as long as the btrfs file system is supported by boot CD) without needing RAID recovery software.
