Adaptec 39320 controler + 6 Fujitsu mas 36gb 15000 rpm drives u 320 the
fastest i could get or is there something else, faster? Thanks


Yes. Flash RAM based HDs. eg.
http://www.bitmicro.com/products_edisk_35_ide.php
Very expensive, but very very fast.

U comp.periphs.scsi Folkert Rienstra prica:

'HostRAID' gives me several references including
"Adaptec SCSI Card 39320(D)-R" product specification pages.
AFAICT the HostRAID support is in the SCSI chip itself so I can't
see how there would be a version of 39320 without that capability.


Hmmm, HostRAID...


Yeah, Hmmm, HostRAID.

My bad, you're right...


After you had been warned.
Some people would make sure not to ****-up twice.
Apparently, you are not among them.

It has got RAID 0/1 support...


Right.

I tried with RAID adapters from Adaptec at this page:


http://www.adaptec.com/worldwide/sup...e=supportindex

Your problem.


All answers were already in that post.


In some other post, not the one I answered firstly, read again...


Read it yourself, (if you can).
"15krpm U320 SCSI" answered all three questions.

Uh, note the write rate--14 to 110. With no moving parts it should be one
or the other, not a range.

Be careful with flash--don't assume that it's faster than rotating
magnetic--one of the big selling points for the IBM microdrive is that it's
faster than the solid state equivalents.

They are fast for a database application (IOPS), but rather slow
(in comparison) for streaming applications (sustained R/W Rate).

Not a good match for OP requirements.

U comp.periphs.scsi Folkert Rienstra prica:

Right.


But that doesn't make it RAID controller... It's normal HBA with RAID 0/1
support... Where are RAID 0+1, 10, 5?

Read it yourself, (if you can).
"15krpm U320 SCSI" answered all three questions.


So, what does that say? 15krpm drive, U320 SCSI, so? Depends on application,
it could be 10krpm U160 SCSI too, and work just as good as 15krpm/U320...

Yes, that does make it a RAID controller, just not an all purpose one.

It's normal HBA with RAID 0/1 support...

Didn't see it excluded either.

5?


Who needs that.
Ok, you can do with less drives but that's offset by a more expensive -yet slower- controller.

Answered all three questions: fast read, fast write *and* fast seek.

just as good as 15krpm/U320...


Yup, and he didn't go for that, so there.
