I have a 10k Fuji MAP and it hit 72,000 on the reads and 65,000 on the writes if that gives you anything to compare to. Its the fastest drive I have. The Atlas 10k IV's just kiss 70,000. They both suck horrible on the writes though till you hit the 64k line on ATTO and they basicaly jump way up to max speed? Sorta weird huh?
Yeah i know, i was very suprised on how high the low end writes / read are, but the top speed is not that high, i would expect at least 60k read. I could be having the 64bit b/w issues that people w/ dual amd boards are having. I have a tyan tiger mpx (s2466-4M). It would seem this way because it maxes out both read and write at the same place and it never gets higher. I will have to look into this. Thanks for the reference information tex.
I get tons better lowend performance on a regular controller as opposed to these raid controllers. In reality you seldom pound out 32mb in half of 1k transfers. If I run it thri the cache it feels frigging unreal in real ife. ATTO really doesn't tell the story with these high end scsi raid controllers because to get the highest ATTO which is pure STR, I have to turn the cache off or I end up capped with 8 drives about what two 4 yearold drives do thru the cache on atto. Real life is totaly differant. It feels very very fast. But I am stiggling to figure out why my new u320 drives are so VERY slow excpet I suspect they are by passing the drives onboard cache.
And.... if those slots on your MP are keyed like normal 32bit slots since they are 5 volt you really should go grab a Perc2 or Elite 1500. I have one sitting here but I promised to Shorty. You can get them dirt cheap as they don't fit in a 3volt 64/66 slot. They are 64/33 5 volt cards and Ultra 2 LVD not u160. But tahts really only a matter of bandwidth per channel. You can get a two channel card for maybe 25 bucks.
You can get a frigginn four channel one for 50 or 60. These have the same CPU's and onboard cache as the bigger 1600's.

Yours did tons better on the low end writes!
