Feeling kinda 'bleh' lately.

Depressed that seemingly simple projects drag on forever. Like getting more space for new servers and upgrading our network connection to the net to gigabit.

Also ticked at buggy software. MIME::Lite send_by_smtp bug (fixed in developer release, not in Debian)... Debian Woody to Sarge upgrade (multiple problems)...

And as always, angry at disks. Two identical machines... one's doing twice the load of the other. Seemingly identical config, kernels, memory, drive controllers, etc. But one has Fujitsu drives, and the other Seagate. Both 15k rpm, though. Could that be the difference between 2x performance? Wtf?

I generally haven't heard great things about Fujitsu drives, but that's more reliability, not performance. You'd think if they sucked they'd at least work well for awhile but then just die.

I think the Fujitsus are the ones doing better.

And frankly, everybody's drives fail. So unless you have hundreds running non-stop, I don't think you can easily made a broad statement like "Fujitsus suck because I had one die once".

It doesn't help that they all switch technology more often than drives fail, so you can never really pick one good company.

I didn't say I had one, I just said I've heard that they suck. It's surprising that the Fujitsu ones are outperforming the Seagates.

Do both type of drives have the same amount of hardware cache ?

Which machine is slower, seagate or fujitsu?

I have a 15k fujitsu disk in my workstation. When it was running kernel 2.4, the system would bite it when the disk was grinding. But that went away in 2.6.

Variety in disk performance...

Yes, our performance guys went out and bought one of every 15k RPM SCSI disks on the market a while back. Then they benchmarked them. The results were shocking. Some were significantly faster than the others, both in terms of seek time and throughput.

Re: Variety in disk performance...

Well at least I'm not crazy then.

Note to self: benchmark disks before we buy 'em.

What does hdparm -t -T think about the drives? That's a pretty bizarre problem...

hard drives suck!

In the past 2 years I've had at home a western digital, ibm, and a maxtor fail. In the past year my sister had a maxtor fail. In the past year at work we've lost 2 ibms and a western digital. (Note all of the failed disks were ide.)

At home in novemeber i built a raid 5 array out of sata seagates so we'll see. Seagate now has 5 year warranty on their ide drives...i'm guessing the scsi had that earlier.

I'm not sure i've ever used a fujitsu drive.

ya but ide disks seem to fail all too often relative to scsi drives.

plus 5 year warranty from seagate for a drive...mmm!

2x load?

there can't be that much difference between those disks-
and all other config is the same huh?
maybe one is sneakily write-caching or something?
maybe the controllers are treating them differently for some reason?
yeah- that's weird.

You work too hard. I mean, you've been doing this since you were like, 2, right? I say scrap it all, disappear mysteriously, and resurface on some remote tropical paradise, spending your days sipping margaritas and rubbing suntan oil into the nubile young flesh of island women. Or you could keep doing that computer thing,with people bitching at you all the time..whatever you think is more fun. :P
