RAID0 vs RAID1 benchmark

FreeBSD 7 amd64.

3ware 8006-2LP storage controller.

2x Hitachi HDS721075K drives

UFS, softupdates.

Blogbench was used as a benchmark tool.

  • RAID 1, UFS, Softupdates, noatime

Final score for writes: 347

Final score for reads : 62382

  • RAID 0, UFS, Softupdates, noatime

Final score for writes: 504

Final score for reads : 65850

Is it really worth using a RAID 0 array?

And while I was at it, I tried UFS vs ZFS, also with blogbench, on a JBOD array.

  • UFS, Softupdates, noatime

Final score for writes: 403

Final score for reads : 66177

  • ZFS, prefetch_disable=0, noatime, nocompress

Final score for writes: 339

Final score for reads : 39167

  • ZFS, prefetch_disable=1, noatime, nocompress

Final score for writes: 338

Final score for reads : 49820
