I got bored and decided to buy a 2nd hand 9.1GB IBM Ultra SCSI HDD.
MODEL: DNES-309170
It has 68-pins

My question is what SCSI card do I need? (I need the CHEAPEST one)
I'm also planning to buy a Seagate Cheetah 36.7GB 10kRPM ST336706LW(68-pins version) to complete my SCSI setup.

And also what kind of SCSI terminator would I need? And how much do they cost?

I bought the IMB HDD for NZ$18, but I just found a suitable 68pin LVD Terminator(new) costing NZ$30!

Ummm...I'm in trouble...

Any SCSI card you like, so long as it has a 68-pin connector. The early 68-pin cards were 40MB/s I believe (Ultra Wide), which should be "fast enough". Better still would be a Ultra 80 card (or U2W). You don't need anything faster unless you're doing a RAID array, in which case Ultra 160 is faster than a PCI slot anyway.

I won't be doing any RAID stuff with SCSI.
Would I get any improvement in performance using Ultra160 since that's the highest bus that Seagate Cheetah supports?

And what about backward compatibility? 68pin->50pin?

68 to 50 pin adapters work fine (and vice versa) but 50 pin connections limit you to 20MB/s max. Remember that the transfer rates of older drives are slower, so an older 7200RPM drive will probably put out around 50MB/s. So Ultra Wide SCSI (40MB/s) would probably be fast enough, U2W (80MB/s) would be better. The nice thing is that the Adaptec 2940UW is such an old card you should be able to find one for around $10.

I just found a HDD&card combo for real cheap with cables and terminators.
The card is a <A HREF="http://www.initio.com/products/info/a100u2wmac.htm" target="_new">Initio A100U2w PCI SCSI</A>
while the HDD is a Compaq 18GB 10kRPM 68pin.

I never knew Compaq made SCSI HDD or are they rebranded ones?

Anyway thanx for the help you've given me so far.

I'm fairly certain they're rebranded drives.

Oh and regarding to SCSI standard, what's the difference between UltraWide3(UW3) and U160?
...are they the same?

And my theoratical guess is 'SCA' has got something to do with hot-swap hence 80pin is that correct?

I believe the UltraWide is the old 40pin connection. Ultra160 uses the newer 68pin or 80pin connection.

There is no SCSI 40-pin. Ultra SCSI was 50-pin (a wide cable but it's called narrow because of the bandwidth) and offered 10MB/s (20 in later implementations).

Ultra Wide SCSI is the first 68-pin standard, 40MB/s (selectable downward).

U2W is the next SCSI standard, 68 pins, 80MB/s (backwards compatable).

U3W is 68 pins and 160MB/s.

I've never heard Ultra 320 refered to as U4W, but it could be I guess, it's 68-pins as well.

So all of those are 68-pin. 80-pins (SCA) is for drive racks, where the configuration is done on the rack rather than the drive (easing swap/hot swap).

Correct.
