The performance difference between zfs-fuse and zfs-linux is less
noticeable if the computer has slow storage.
The green HDDs are likely to be the limiting factor in this hardware
configuration. Depending on the particular model, you're not likely
to get more than 20 MB/s for sequential IO and maybe 10 MB/s for
Also remember that an 890FX or 990 series chipset is required for ECC
memory support with an AMD desktop CPU. Asus is the only manufacturer
that clearly states whether their AM3 and AM3+ motherboards can
actually use ECC memory. For others, it depends on firmware support,
which is inconsistent.
