Date: Sat, 17 Jan 2009 18:18:06 +0100 [thread overview]
Message-ID: <20090117171806.GA9432@lazy.lzy> (raw)
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,
