How fast will the SCSI go..?
I have an Athlon XP based Windows XP machine that currently runs an ATA 100 5,400rpm 20gb drive as it's main drive.
I have in my hot little hands a HP Ultra 10K SCSI-3 drive with the hot swap plugs and also another HP 10K SCSI2 LVD drive.
My question is this - I can only use a SCSI card I have here, an Adaptec 2940UW card with the 68pin etc connections - but what will performance be like?
Or, more specifically, will performance be better than the current ATA100 drive in there..?
They are both 9.1GB drive models but are server-type drives not installed as yet, they are new. I have read on the product specs that the 2940UW supports SCSI1,2,3,and UW so it should support both the SCSI2 LVD/UW and also the SCSI3 right..?
Please let me know as I am dying to know if I should even both with copying the partitions etc and going through the general associated pain if performance will not be much better? both SCSIs are 10k rpm drives whereas the IDE is only 5,400rpm and if the 2940UW supports the SCSI1,2,&3 then there should be excellent performance? or am i missing something?....If necessary, I can run only the SCSI3 Ultra 10k drive on the scsi card, hence one drive can make full use of its bandwidth, even if its not the newest card..?
what will it go like?? or with both new scsi's connected, for instance? please help

OK I got that part then, but is it then possible to use the 2940UW to control the SCSI3 UW drive? I am just about to get the adapter to plug it into the port on the controller, as at present it has the hotswap port.
Will it provide good performance still? I know I could go buy the latest adaptec card, but I want to know how the Ultra 3 10K will go in SCSI3 mode on the 2940UW...apparently it supports it (on www.adaptec.com)
Thanks

You CAN use the 2940UW with the SCSI3 UW drive. You may need a special cable or adapter to get the connectors to mate.
The performance will be good but not as fast as the drive is capable of. But certainly not what I would consider POOR performance.

I've got (amongst other devices) an Atlas III and an Atlas V controlled by a 2940UW myself. Altas V has a U-SCSI 160 interface (68 pin). The 2940UW does so too, so no special cables are required.
Performance is 12-15 MB/sec.

I sugggest an Adaptec 29160N as a current model SCSI adapter that supports LVD.
