All we know is that you use 2 disks and md. This is like posting to a TCP/IP architecture group and saying you have a network connection and want performance advice. Read up, supply full config info, run benchmarks, then ask specific questions. GI=GO.

Hi all,
I'll have to setup some machines with two HDs (each)
in order to get some redundancy.
Reading the MD features I noticed there are several
possibilities to create a mirror.
I was wondering which one offer the best perfomances
and/or what are the compromises to accept between
the different solutions.
One possibility is a classic RAID-1 mirror.
Another is a RAID-10 far.
There would also be the RAID-10 near, but I guess
this is equivalent to RAID-1.
Any suggestion on which method offers higher "speed"?
Or there are other possibilities with 2 HDs (keeping
the redundancy, of course)?
Thanks a lot in advance,
bye,
