I think you need to try running a real benchmark like bonnie++ against both.
For example, you run time dd but you don't include the sync in the
time...

Hello Daniel Iliev,
Here we go. I think the results can't be interpreted unambiguously.
Perhaps I'll use a benchmarking program in the weekend to get clearer
results.
I've found time to move things off the RAID to I can compare with freshly
formatted filesystems. LVM on top of RAID-0 is

Omitting LVM isn't an option, I'd lose all the flexibility that LVM
offers. I don't see why RAID-0

So your tests show that RAID-0 is

across the drives anyway, am I gaining anything from the RAID-0? Would I
be just as well off by adding the two partitions directly to the LVM
group?
Hi, Neil
I have to admit I've never made such tests and I'm guessing here but I
would say that you
I have two SATA drives, I have a partition on each combined as RAID-1 on
which I use LVM to create my important partitions (/usr, /var, /home
etc). I have another pair of partitions combined as RAID-0 on which I
have another LVM group containing less important partitions, where speed
and space
9 matches
