as i know raid0 is to increase speed perfomanse and i/o right?
so my system is
cpu athlon II 250 e
mobo asus a78td evo
host adapter lsi 9211-8i
i run hdune 4.01 trial
with a single drive and i get according to hdtune
for 1mb file transfer 166 i/o and 166mbytes/sec speed
at 2 drive raid 0
for 1 mb file transfer 323 i/o and 323mbytes/sec speed
so far so good and those values with the controller of the mobo
so when i see the numbers according to hdtune
for 512bytes 4k and 64k transfer rates i have the same numbers
at single drive and at raid-0 configuration!??!?!
i use the lsi card at raid0 for the 1mb i see an increase from 166 to 231 but again for 512byte 4k and 64k the numbers are the same.
i go to raid-0 with 4 disk configuration
the mobo raid gives at 1mb 598 and the lsi 450
and both of them at 512bytes 4k and 64k the same numbers
1)should not see an increase at those numbers also?!?!?!
i2)s it logical for the lsi to have such a worse perfomance again the raid controller of the mainboard?? (at the 1mb transfer it is 25% slower)
