harddrive bottleneck (seek time) raid 0 or raid 1 better?

[mishkin]

As the subject asks which is better(HW raid)... I was thinking raid 0 for sure but that more helps sequental transfer speeds

what were interested in is random seek data xfer rates (lots of files being requested in small chunks from all over the place)

Yes I know a single ssd would own eve raid 5 for torrenting but thats too expensive (next to 0 seek 0 access times and pretty fast xfer)

With raid 0 it can read half the file off one drive and half the off the other, but both need to find/seek at same time to get the file

with mirroring it can seek one file out and read it (maybee taking a little longer to read) and at same time seek out another file and read it too (but maybe taking longer)

It's like we have 2 scenarios

there are 2 targets close to eather to be bombed and 2 others close to eachother but far from the first

which is better?

send 2 bombers to one site then the other

or send 1 bomber to each location at same time

now for this metaphor to work the bombing of said sites would take a while (think a provence/state as the target)

heh if you had a ssd it would be like having 2 bombers that can bend space and time and teleport to the target But every use has a chance of running a component (they die fast from torrenting)

anyways discuss away

OH and ps I can't do raid 5 because R200 servers only take 2 drives

edit: I care not for redundancy, this is why raid 1 is soooo much more common in server world not only is it almost as good as raid 0 but it's redundant
