I'm looking for 15rpm HD's to get. But their controllers are more expensive than the drives.

I've chosen between the
HITACHI Ultrastar 15K147 36.7GB 15,000 RPM 16MB 68-pin Ultra320
HITACHI Ultrastar 15K147 36.7GB 15,000 RPM 16MB SAS(Serial SCSI)

The SAS controller is $251 so I'm going with the Ultra320. I have a question about the choice of controllers for the drive:

Can you still connect a Ultra320 drive up to a Ultra160 or SCSI-3 controller? Since it's only 1 Drive I won't need 320MB/Sec pipeline since the drive can only pump out 60-90MB/s anyways.


EDIT: Fixed product error

Would both these controllers work?
This controller only supports up to SCSI-3 133MB/Sec Transfer rates:
ACARD AEC-6712UW PCI SCSI Ultra Wide Adapter Card - Retail (http://www.newegg.com/Product/Product.asp?Item=N82E16816123102)

This controller only supports up to Ultra160 160MB/Sec Transfer rates:
ACARD AEC-67162 PCI SCSI 2-Channel Ultra160 (http://www.newegg.com/Product/Product.asp?Item=N82E16816123004)

The LSI20320-R is an Ultra 320 card not scsi 3 and yes you can U320 drives to U160 cards.

Sorry about that, I fixed the first link.

Would a SATAI cable work on a SATAII HD?
Would a SCSI Ultra160 68 pin cable work connecting an Ultra160 68 pin controller to an Ultra320 68 pin HD?
Would a SCSI Ultra320 68 pin cable work connecting an Ultra160 68 pin controller to an Ultra320 68 pin HD?
Thanks for the help.

Would a SCSI Ultra320 68 pin cable work connecting an Ultra160 68 pin controller to an Ultra320 68 pin HD? Yes

Quite frankly if you want scsi then pick up a U320 or U160 controller off ebay or the like. They are dirt cheap, I sold my LSI U160 controller for £16 yesterday.

Depending on where you are and if you still want SCSI stuff to get started, I've got a bunch of stuff sitting around that would look a lot better in someone else's computer than on my shelves!! Just let me know and I'll put together a list.

Been here a while and some would say I'm an honest guy!!
