ok this is it for me... im startin to hate scsi before i even started usin...

ok here are 3 devices and one controller card, all i want to know is if i can run the three of the same card with no problems/issues...thx!

Device1: Seagate Cheetah X15 36LP
Model Number: ST336752LC
Capacity: 36.7 GB
Speed: 15K rpm
Seek time: 3.6 ms avg
Interface: Ultra160 SCSI
Suggested Resale Price*: $699.00

Seagate is introducing what no other disc drive manufacturer can: 2nd generation 15K RPM experience, reliability, and performance. Cheetah X15 has doubled the capacity with 36 and 18 GBytes. The Cheetah X15 36LP has seek times as fast as 3.6 msec and data rates as high as 69 MB/s and supports Ultra320 SCSI and 2 Gbit Fibre Channel interfaces.

Device2: Seagate Cheetah 73LP

Model Number: ST373405LW
Capacity: 73.4 GB
Speed: 10000 rpm
Seek time: 5.1 ms avg
Interface: Ultra160 SCSI
Suggested Resale Price*: $980.00

Seagate continues its lead in Enterprise Storage. Seagate's fifth generation of Cheetah products include the Cheetah 36XL and Cheetah 73LP. This family of 10,000-RPM drives supports capacities from 9.2 to 73.4 Gbytes and seek times as fast as 4.9 ms in a 3.5-inch form-factor for mainstream and high-performance users. Interface options include Ultra160 SCSI and the new 2Gbit/sec Fibre Channel.

Device3: Sanyo BP5 24/10/40 CDRW

The CD-SAN-BP5 is SCSI-3 CD-RW drive featuring a Half-height form factor that enables you to record data with the world's fastest 24x speed.

Feature:
24x Write / 10x Rewrite / 40x(CAV)Read
SCSI Interface, 50pin IDC connector
Buffer size: 2MB
Half-height PC Built-in Type
Access Time 130 msec (CD-ROM/R)
Access Time 130 msec (CD-RW)
Dimensions: 148.0(W) X 192.4(D) X42.3(H)mm

Controller: Tekram DC-390U3 Ultra160

Ultra160 Low Voltage Differential SCSI Controller kits. Internal LVD SCSI Cables and Terminators included.

* High speed 64-bit 5.0V PCI bus master (Also Compatible with 32-Bit PCI Slot)
* Max Xfer Rate Supported is 320MB/Sec using Dual-Ultra160 channels (DC-390U3D)
* Maximum devices supported are 30 LVD or SE (DC-390U3D)
* Includes Bootable CD-ROM with Diskette Make utility and (2) Internal LVD Cables & Terminators (DC- 390U3D)
* Flash BIOS for easy Upgradeability

The DC-390U3 Series controllers support the new Ultra160 SCSI standard for improved speed and reliability. A subset of the Ultra3 specification, Ultra160 adds the following features to Ultra2 LVD:

DTC (Double Transition Clocking) clocks data on leading and trailing edges, and is responsible for doubling the max transfer speed to 160 MB/Sec.
CRC (Cyclic Redundancy Check) enhances data integrity at higher bus speeds by improving upon parity checking.
DV (Domain Validation) verifies optimum SCSI Bus configuration by rigorously testing each device for the fastest possible, yet safe, transfer speed.

Ok *sigh* this is it!! Thanks for the help y'all! Its R E A L L Y appreaciated! ;) :)

i L O V E you pariah!!! thx so much!!! :)

so the hds would be on one channel and the cdrw on the other huh?

That will work fine as long as you put the drives on one channel and the CD on the other. This avoids the downshift of the drives to nonLVD.

btw scsi vs ide burners....both same 24/10/40 burn proof etc etc

only difference i assume other than interface is access time

would the performance would be identical?

could i like burn stuff whilst i play quake n stuff with a scsi burner and not with ide?

is the twice the price, and then some, worth it for scsi?

you can play quake while burning w/ scsi



<< is the twice the price, and then some, worth it for scsi? >>


that would be up to you

YOU SUCK!!
I WANT!!
I WANT!!
I WANT!!

ok, I'm done now :D
>>



its ok i understand...! :D lol

hmm its either 200 bucks for a sanyo scsi one or 100 bucks for aopen or liteon ide one.... oh the pain....

I want to add something to the other comments.

I have not read your other posts. So hopefully, I do not just repeat.

There are two different models for the Seagate Cheetah X15 36LP. Make sure to get the ST336752LW.
THIS IS NOT THE ONE YOU HAVE LISTED!!! The ST336752LC uses a 80-pin SCA connector. The Tekram DC-390U3 does not include an 80-pin SCA
cable or connector. You would need a converter with the model you have listed. Make sure to get the LW!

There are three different model numbers for the Seagate Cheetah 73LP. Make sure to get the ST373405LW (as you have listed)

Seagate's [edit] model numbers end with [/edit] letters as follows:

DC = Differential, 80-pin Single Connector Attachment (SCA)
FC = Fibre Channel, 40-pin SCA
FCV = Same as FC, but with an increased cache size (Recommended for Video applications and applications with large file formats)
LC = Low Voltage Differential, 80-pin SCA
LCV = Same as LC, but with an increased cache size (Recommended for Video applications and applications with large file formats)
LW = Low Voltage Differential, 68-pin Wide SCSI Connector
LWV = Same as LW, but with an increased cache size (Recommended for Video applications and applications with large file formats)
N = SCSI, 50-pin Narrow SCSI Connector
ND = Differential, 50-pin Narrow SCSI Connector
W = SCSI, 68-pin Wide SCSI Connector
WC = SCSI, 80-pin SCA (Hot Swappable)
WD = Differential, 68-pin Wide SCSI Connector

The Tekram DC-390U3W has 2 channels. One channel is Ultra 160 LVD, the other channel is Ultra-Wide SE. It has 4 connectors: 3 internal, 1 external.
The internal connectors are a 68 pin LVD, a 68 pin SE, and a 50 pin Ultra/SCSI-2. The external connector is a 68 pin LVD.

Make sure the place you buy it from includes all the SCSI cables. 4 cables and and LVD terminator should be included. Unlike IDE cables, SCSI cables
and LVD terminators are not cheap. You could end up paying more for the cables than for the card if you do not buy them included (slight exageration).

You will want to plug the Seagate Cheatah X15 and the Seagate Cheetah 73LP onto the internal 68-pin LVD, Twister Pair cable (it has 6 connectors) and the other end plugs into the internal 68-pin LVD connector (there are two 68-pin internal connectors, make sure it is the LVD one).

The Sanyo BP5 24/10/40 CDRW will plug into the internal 50-pin Ultra/SCSI-2 cable. The other end of that cable plugs into the internal 50 pin Ultra/SCSI-2 connector.

Then comes the issue of termination. I am pretty sure the Sanyo BP5 comes with a termination jumper, make sure it is on the end connector on the cable and the termination jumper is on. On the other cable I would use the included LVD terminator on the end of the cable and not have termination on either of the hard drives.

Then comes the issue of SCSI Id. The Tekram controller should have a SCSI Id of 7 on both channels. Set your boot drive to SCSI Id 0, and the other drive to SCSI Id 1. The controller should also have the option of specifying the boot device by SCSI Id, specify 0. You can set the CDRW drive to any SCSI Id other than 7. I would use 0 or 3.

When booting up you should see two different channels with the hard drives on one channel and the CDRW on the other channel.

I hope this helps and that you buy the correct Cheetah X15 drive now. I also hope someone double checks what I have written. I have installed hundreds of SCSI systems but most of them are UN*X servers and not PCs. My main home computer is a SCSI PC though.
