Hi,

I'm looking to get a 10400rpm scsi hard drive, but i dont have a scsi card and I dont really know where to start. i already have a 30gig IDE drive (5400rpm- now u know y i want a 10400rpm). A basic outline of how i could do this would be much appreciated. I'm looking to sell the 30gig and keep the scsi as my primary boot drive, is this a bad idea?

Also, how many drives can i connect to one scsi card? (ie a hard drive and a cdrw)

Thanks. .....blah blah.... best of my knowledge, etc. "always in the quest for knowledge, and glad i could help"
If im wrong, its not my fault!
 
You need to start with a controller for the SCSI HDD. You should be able to find one @ Best Buy, or any local shop. Once it is in place you can put (I believe, if I am wrong someone tell me) 7 devices on one internal SCSI chain. Starting at 0 for the HDD and 1 for the CDROM (If its SCSI)
Once you have the card in you should be set.

There will be other issues, but nothing you can't handle. And the extra cost. Ed Fair

Any advice I give is my best judgement based on my interpretation of the facts you supply.

Help increase my knowledge by providing some feedback, good or bad, on any advice I have given.

 
adaptec 19180 should be the card of choice. a decent cable is also a must but when i bought this type of card they supplied the proper cable with a terminator at the end, it was only sufficient for 3 devices on that chain though but i assume this is ambpe for you.
 
hi

get the scsi Adaptec A2940UW, it's like 70 dollars on sale at i think i spell it right....it's on the clearance list.

it's a great scsi card...

type transfer rate
SCSI2 = 10 MB
ULTRA = 20 MB
ULTRA WIDE = 40 MB
ULTRA3
 
Go with any Adaptec card. Avoid the "no name" SCSI controllers. Why? Because a year or two from now when you need new drivers or add other devices, you'll find drivers for Adaptec - and probably not for the off-brands. A few $s saved today will be totally wasted next year when you have to pitch the off-brand card!

- Example - I recently added 2 18 GB UW3 drives to my NT server at home [duplexed] with 2 other non-UW3 drives on a 3-4 year old 2940UW PCI card. Had some unique cabling issues that were finally solved with a $18 Adaptec 50-68 pin adapter and upgraded drivers.

- There is theoretically a way to hang more than 7 SCSI devices on a single channel by using LUNs [Logical Unit Numbers - sort of a SCSI ID sub-addressing scheme]. But watch this - can have serious issues w. drivers, even Adaptec's!! Plan on no more than 6 devices on a single channel [the adapter uses one SCSI ID]. Up to 13 on a dual channel card.

- Remember, your disk R/W will speed up - but you're not improving your processing any! And because you typically don't R/W to multiple drives simultaneously on a workstation, you won't see the sort of throughput you're used to seeing on a server!
