We had a 3020 and an R200. I am pretty sure neither could do more than 30megs/sec, and an 5+ yr old dual drive 2650 in RAID 1 outperformed such 'enterprise' storage. I wish we could return both..

Interesting, as you seem to have an array from their 'entry level' line of arrays.. Could you elaborate on the speed you pushed it to?

We have arrays that can do 200Megs/sec and 300Megs/sec on sequential writes, and they can be had for the price of a luxury car or an SUV, but not the NetApp, and their support seemed fairly useless (them: 'you don't have enough spindles', us: but a scsi drive outperforms your aray, them: 'nah, buy more stuff from us')..

I am glad your experience is different from mine, but if I had to buy again, it wouldn't be NetApp
