SCSI Drives

albertross_2

yes eide/ide are effectively the same nowadays.

To get the scsi one to work, you'd need a scsi card as already suggested..

Thanks for that.

You say effectively the same. Googling bought me an answer - says that it is basically faster and replacing SCSI oops haha!!

But can I use my current hardware with it? I'm not too sure you see!?

Thanks again all.

Matt.

Read it as the same.. IDE is the old standard, Eide is the enhanced, they are backward compatible, and use the same connector. All modern drives are EIDE.

SCSI is historically faster, but more complicated to use, generally used in servers. EIDE is sufficient for most people. A modern EIDE drive is faster than a scsi drive from a few years ago.

Thanks!!!!! You've been a great help, all of you! I think that's all my questions!

Let me know if I can help you with anything (I doubt I can, you're all geniuses!! )

Hiya AGAIN!

I just receieved my SCSI Drive.

It is an 80 pin drive. All the SCSI PCI devices on ebay are like 50pin, 68pin etc! I don't know which one to choose.

Could anyone help me find all the hardware I need to buy. I can free a PCI Slot on the motherboard! And what cable should I be getting. I'm pretty good with software, but hardware - talking to me is like talking to a kid.

I need to connect the drive internally.

Many Thanks,

Matt.

What speed card would you recommend?

I compare these two for example:

http://cgi.ebay.co.uk/SCSI-CONNECT-2904-ADAPTEC-PCI-NEW-BOXED_W0QQitemZ290029020300QQihZ019QQcategoryZ90718QQrdZ1QQcmdZViewItem

http://cgi.ebay.co.uk/Adaptec-SCSI-Card-29320-R-PCI-X-Ultra320-SCSI_W0QQitemZ130025552835QQihZ003QQcategoryZ90716QQrdZ1QQcmdZViewItem

The second is way more expensive, it is Ultra320.

The spec for my drive is:

Drive Features

* High recording density adopting Advanced Giant Magneto-Resistive Head (GMR) technology and 32/34 MEEPRML recording code
* Large capacity 18.4GB with 3.5 inch and 1 inch height

I want the very best performance, with a reasonable cost. If I get a converted (x Pin to 80 pin), then is there any performance loss in there!? And what cables do you recommend?

Sorry for so many questions. All your answers are so appreciated

There are differnet types of SCSI buss types.. all depends on how much data your trying to throw though the PC. So yes the card does make a difference. Also the major difference with SCSI is it does all the work for the disk and not your processor.

Tbh SCSI is mainly for servers where performance is important vs the cost. Maybe you should post the make / model of your disk ..easier to recommend which to go for then.

You need 2 adapter cards:

1. SCA 80 pin to SCSI 1/2/3 68/50 pin, e.g. http://cgi.ebay.co.uk/SCA-80-pin-to-SCSI-1-2-3-68-50-Adapter-Card_W0QQitemZ290031264429QQihZ019QQcategoryZ31494QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

2. An Ultra 160 SCSI PCI card to go with your Ultra 160 drive, e.g. http://cgi.ebay.co.uk/Adaptec-29160N-PCI-Ultra-160-SCSI-Controller-Card-VGC_W0QQitemZ190032663420QQihZ009QQcategoryZ90716QQssPageNameZWDVWQQrdZ1QQcmdZViewItem. The first adapter card in your post above is 10Mb/s and will therefore reduce the transfer rate, whereas the second adapter card is 320 Mb/s and is overkill because your drive would still transfer at 160 Mb/s max.

You also need cables:

1. 80 pin SCSI cable to connect drive to SCA 80 pin adapter. (This may have come with the drive).

2. 50 or 68 pin SCSI cable to connect SCA 80 pin adapter to 50 or 68 pin connector on PCI card.

3. Power cable to connect SCA 80 pin adapter to PCI card.

Also, jumpers to set SCSI ID and termination on the SCA adapter.
