NF3250 native SATA - any reason to use SCSI anymore?

And you've also seen the Tempter, and he's yellow with black spots and a sassy smile, not red with horns as widely supposed.

Hey you two, you cost me a grand also, and I'm still waiting on a 64 bit slot....

5 to 1 I will have one before the year is out.....

SCSI is frikkin addictive......

Hey, you didn't expect me to go broke all by myself, did you?

ps
I have this insane NEED to run my card in a 64-bit slot. I HAVE TO SEE FOR MYSELF whether it's worth it or not.

/waits for Shuttleteam to chime in with tales of the promised land

Things can go downhill in the finance department rather quickly!

You buy a SMP board to use 64/66...

You use one processor and minimal memory amounts, say 512MB.

The itch to buy a second processor takes over, so you do that.

Then you want another 512MB for the second processor.

Then you realise that your card supports only 64/66 and your board has 133 PCI-X so you buy a new HBA.

You want to use write back caching on that HBA so you need a battery.

You want more cache on the HBA so you buy that.

4th generation 15k drives are announced so you start saving $$$ for those.

It's kind of hard to save the $$$ for the above since you sold your car to pay for what you have so far.

There are new video cards on the way, another $500!

Sounds about as bad as compulsive gambling!

EDIT: Forget overclocking in this realm. It is not necessary. Sure if you buy a Honda, you may want to use aftermarket add ons to gain performance. When you buy a Porsche or Ferrari, those things are unnecessary!


Cheers!

:music: The pusher-man...oh, the pusher-man...he's a bad man, the pusher-man! :music:



Even though my HBA is only U160, I would be very happy getting into the 140MB/s realm.

We'll see what happens with motheboards in the next few months. Good stuff on the way.

Dual Raptors on a Via 8237 Southbridge.... (RAID O)

HD Tach reports average read speed of 128.3MB/s

:Q Wow. Just wow. That's a faster sprint than my SCSI setup. Fastest I've seen is 122MS/s. I can do many disk-intensive things at once though, so that makes up for the small loss.

/grumbling about 66MHz PCI slot...I need one!!!!

Don't fear, those HD Tach results are meaningless when it comes to multi tasking. I ran HD Tach on a system with 10 15k.3 disks on an Enterprise 1600 running at 32/66 and got a pathetic 55 max 35 min 60 burst.

Multi tasking was smooth as silk still.

I've used raptors on Silicon image RAID and they "feel" a little snappier than say a 7k250 hitachi. Pour on the load and they founder like most IDE stuff.

Running them on a LSi SATA 150-6 was a different story, however. Both the 7k250 and Raptors were very close (due to the hardware HBA no doubt) and the system multi tasked similar to the Elite 1600 system. Of course the SATA counterparts don't have upgradeable cache (one slash) and no provision for a BBU (five slashes!) which is inexcusable for "enterprise class" storage. This is why anything "enterprise class" always has SCSI in it.

If you really want to see high STR numbers, go with six or eight 74GB raptors on a raidcore HBA. Great HD Tach/WB99 numbers. Adequate to mediocre multitasking, however.

PM me if you wish to discuss further details on what multi tasking consists of and whether or not your storage system is up to the task.


Cheers!

Thanks Shuttleteam. Educational as always.
