SCSI or EIDE

[more]

I am thinking about buying a Seagate 10,000 rpm SCSI drive.

Do any SysOpt members use these types of storage media

for the location of the operating system? With the correct adapter

on a SR7-8X, I should not have any problem. Trying to convince

myself this is a worthwhile move.

The thread "SCSI Disk" started by jmhc is very informative.

But, I would still like to here any suggestions if anyone cares

to reply.

Great choice.:D

More than worthwhile, you won't regret it. :)

If you have the cash to spend SCSI is still the best choice for pure performance.

It's an investment, the SCSI drives you buy will still be in use long after the computer hits the trash can.

Let me refine this advice. In a multiple-drive scenario, SCSI is the way to go. In a single-drive setup, a 7200RPM 8MB cache drive can actually be faster than SCSI.

Depending on what you are doing with the machine in question.

Depending on the hardware, what SCSI drive vers IDE, SCSI controller....what motherboard, CPU, RAM, etc.

In 98% of conditions SCSI is the better choice, the other 2% are up in the air.

I haven't seen many machines that couldn't benifit from SCSI drives.:D


Edited to add:

I am not saying that IDE is a waste of time at all. I have machines running IDE HD's and they work fine.

But you take say an older machine for example like a 1 GHz running Win 2k with IDE drives then Put a SCSI Controller in and a 10k Cheetah. You will notice the difference.

One notch up from that are the 15k Drives..... :D

I have several machines that are running SCSI. I would recommend that you get two SCSI drives if possible. That way you can put your system on one drive and the swap file or partition on the other drive and get the best of the benefits of SCSI. Also, don't forget that with SCSI you can add external peripherals easily.

My main system is as follows:

Abit KT7A-RAID
Athlon Tbird 1400
Adaptec 19160
(2) Quantum Atlas IV 9 Gig Ultra160 SCSI drives
ATI Radeon 9000
SB PCI 512
3Com 3c905
56k ISA modem
TEAC 32X IDE CDROM
Lite On 24-12-40 IDE CDRW

another system:

PCChips 726MRT
Pentium III 450
Adaptec 2940Ultra
(2) Seagate Barracuda 4.5 Gig Ultra SCSI drives
GeForce 2 MX
3Com 3c905
Toshiba 16X SCSI CDROM
CMedia 8738

Between the two systems, I can share my external SCSI CDROM, CDR, and tape backup drives. I have the IDs preset, so I just plug the device into the back of the machine before I boot it, and it works fine.
In general , you will free up your CPU for more work by adding SCSI by reducing the amount of overhead required for data transfers.
I also have a SCSI card (AHA2940) and drive in my server, so that I can dual boot by switching the boot drive in the BIOS. That way neither OS is aware of the other.

Well, I bought the SCSI drive. It is a Seagate 10,000 18 GIG. Also

bought a card and ribbon. Less than 200.00 US, so not too bad.

OS is in. Haven't run benchies yet but I really don't need to. The

drive seems to react more quickly than my Maxtor 40G 7200 rpm

ATA133. Maybe it is psychological. Install went smooth. Thanks to

everyone who replied. Thanks Ankerson.[COLOR=blue][COLOR=crimson]

i agree, i got a 15k rpm scsi drive..... i am not having an easy time making xp boot from it, but when it does it boots faster then ANY raid 0 setup i have seen, the progress bar goes across 1.25 times before hitting login! and i have alot of cards in my rig too, sblive, nic, scsi, offboard ide controller card, so its not that i have a lean machiene.

the main thing in load times, are gonna be the drives seek times, where SCSI excells, my 15krpm fujitsu MAM drive is ruffly 6ms seek, while say an ibm 60GXP is closer to 15ms, unless you are reading/writing alot of data in sequence, those seeks times are what will make or break a program's load time.

more-

Just wanted to point out that SCSI is faster by virtue of the fact that it is a smarter interface than IDE and that it does not take up as much CPU utilization as and IDE type interface would! That is why the very first true multimedia machines used such an interface controller type e.g.- Apple Macintosh and actually seem to run faster than its IDE controller counterparts!

SCSI is still way ahead of IDE technology! Just quite expensive. People who use SCSI know of its versatility over the IDE controller interface and its many advantages. That is why you can't go wrong going SCSI. Anyone who says otherwise have no first hand knowledge of the differences.

All I can say is you've made a good choice and happy computing.

SCSI no doubt but after seein Bill's pics on WD800JBL...thats some monster drive man:eek:

[$1500-P4 gamer]

Hehe I got that drive and it is FAST. Got some old scsi here too on older systems. But still in single disk setups like BPB said a GOOD IDE is all ya need. Unless you do multi-hdd, or need extremly long life out of it why even bother? THey certainly are one thing-louder and hotter but they are also good for certain uses. Just dont see them being the most important part of a kick **** desktop. Specially if you dont like slow cold boot times! IDE is def faster there.:t

[Ankerson]

$1500-P4 gamer,


I don't now About all of that.....

My 15K Cheetah boots pretty fast. :D

The only slow down is the SCSI bios...just afew seconds, no big deal there.

FYI,

The new Cheetahs run cool and aren't loud.:)

[$1500-P4 gamer]

"The only slow down is the SCSI bios...just afew seconds"
Yep thats what I mean and the motor spin up time. I run 6 seagate Berricuda hdd's and one cdrom-it takes a little for boot. But I am sure the newer is faster.;) It has to be.

Yeah I remember those. You have to cover the case with sound proof stuff so the noise from the drives don't shake your whole house.:D

And you need like a 300cm fan to cool each one. LOL :D


Ahhh Those were the Days....:D


I remember the first 10K SCSI drives....man they were loud. :t

[Someone Stupid]

I have two 15K 73gb Seagates on RAID 1 which run excellent. With all of windows in pagefile, and not restarting much, I use a partition off the 120 WD 8meg Special Edition - gets better performance numbers than the 80 WD BiPolar thrown up. It is an investment though - as the drives don't die like IDE ones do. If a SCSI one does, it's going to either be a curse or blessing. It will last forever more than likely you'll be begging it to die in most cases - just there are VERY VERY RARE cases.

:D

Drool....:cool: :t

[Ankerson]

Someone Stupid,

I have been looking at those 15K 73 gb Cheetahs lately...

Thinking about putting 4 of them in my server....then moving my 4 36gb Cheetahs to my other machines.....Leaving the 18gb for the OS.

Well I only spend money on my network Bill....:confused:

I don't have any bills.....I am Divorced...:D

[BipolarBill]

Well, 2 15K Cheetahs on a SCSI RAID controller (prob. U320) ain't chickenfeed!

I would have to get a U320 Raid controller to take full advantage of the drives.


But I can eat hotdogs for a few weeks. :D

lol, mine has 28 fans! Loud and HOT! Never failed though, even in a portable trailer in the summer without air conditioning! I about had a fit when I found out the studio owner had shut off the air out there! :eek:

I see somebodies bugged about booting so maybe this will get you into xp a little quicker, I've sort've been spoiled on it but reinstalling xp earlier reminded me of it

Open regedit

Browse to hkey_local_machine/system/currentcontrolset/control/sessionmanager/
memorymanagement/prefecthparameters

Change the value of 'enableprefetcher' to '5'.

'3'is the default value.

So now instead of waiting for that scroll bar on the welcome to go by about 5 times it just makes one pass and your in.

Cool, thanks.

I have been looking for that for awhile. I forgot were it was.:D
