Hey all, I was curious about some SATA/SCSI controllers and wanted to ask anyone who has hands on experience with high-end SATA/SCSI controllers.

With my next build, I dont want to hold back performance in anyway (probably a $6k+ machine). I want to get 2x 150-200GB (10K RPM) drives as primary in a striped array and a 500+GB for storage. My biggest concern is the primary as far as performance goes.

As for SATA drives. How much performance gain would I get using a seperate controller with its onboard processor? Is it comparable to say Ultra320 SCSI?

I was thinking about this: http://www.lsi.com/storage_home/products_home/internal_raid/megaraid_sas/megaraid_sas_8408e/index.html



Now for SCSI. Would a Ultra320 SCSI controller be significantly faster than a SATA controller like the one above? Also, I hear SCSI drives are loud... Are there "quiet" drives?

honestly if you have never played with scsi, stay away and just go for a 4x or 6x sata raid config, its much easier to deal with and if one of the drives goes bad you dont have to go through all the bs to try and get it replaced...ive heard there are sata controllers now with cache, if you can find one i would go that route.

haha, thats funny. That was the first controller I looked at... I heard that LSI was the best though.

If I'm not mistaken, LSI had a hand in the PS1, and that's also where Jen-Hsuang worked for a while, if I'm not mistaken.

Also, sata 300 drives burst read rate are just 20 MB/sec less than the scuzzy three-twenty's max burst rate.

The Hard disk makers need to quit bein' a bunch of dairy hicks (hairy dicks) and release some damn hard drives with 32 mb cache buffer.

They would be mother ****in screaming fast.
