Ide raid slower benchmark then no raid?!

darufe · 11-16-05, 08:05 PM

I just tried a raid 0 setup with my 2 old 80 maxtors did 16k stripe and now according to benchmarks i went from
aprox 8ms seek time to 14ms
100ish burst to 60ish
48meg/s to 60ish

Did i just do a fresh format and set up that raid for nothing?
would going to 64k stripe be better?
Could it be a setting somewhere i messed up?
jumpers on the hdds?
Or does ide raid just suck like that?

same exact drives ?
did you low level format ?
what is the purpose for raid ? stripe size plays a difference but i dont think its huge
also do you have all current drivers and such installed for your pc (obviously raid drivers too)

RAID always increases seek times, that could also afffect burst speeds (which isn't important), but your small gain in sustained bandwidth is right.

RAID 0 just really isn't that great IMHO.

By "2 old 80 maxtors" does that mean PATA? So the ITE RAID controller? If so then that's the answer right there. Cheap PCI controllers are never as fast as a southbridge controller.

If they are SATA on the ICH6R then something isn't right.

2x ide maxtors on the yes very crappy ite.
Sorry for the slow response had to reformat after like the third reboot fun eh?
lost all my file too :P

so im getting rid of both ides and getting a250gb sata2 16mb cache tomorrow.

My comp used to run much better with that stupid ite disabled completely in bios so thats it ditching the thing completely and going sata.

screw ide
screw ite
and screw raid 0

I like my RAID 0

Sleepy_Steve · 11-17-05, 10:44 AM

My raid 0 is nice, but i do think people make too big a deal over it.
I like it for different reasons than most.

- fewer drive letters in explorer
- bigger total size of my system/application drive
- and oh yeah, sustained read/write went up on the drive cause its on a board that allows it to sit on the north bridge SATA 4TW!!!

Then again, north bridge SATA raid 0, and controler card / southbridge IDE raid 0 are completly different animals IMO
... i think i went for the default stripe sizes (128k) cause i figure the diference wouldnt be that noticeable, and having bigger stripes prolly coouldnt hurt seek times any more than raiding in the first place.

I'm not aware of any Northbridges that have drive controllers...

Sleepy_Steve · 11-17-05, 05:10 PM

i875p Chipset bro.... ich5r ran off the northbridge.

the via raid 1/0 sata chipset offered in addition to ich5r on some other boards sat on the southbridge.

wait looks like im wrong... oh well perhaps im on crack
but i could have sworn i saw a controler on the northbridge of an 875p chipset diagram once

JCLW · 11-17-05, 05:16 PM

The ICH5R (I/O Controller Hub v.5 RAID edition) is the southbridge.
