SCSI UW 7200RPM Hard Drive vs ATA100 7200rpm Hdd ???

[Tr0LL]

My dad runs a Scsi setup (adaptec 2940UW) in his computer. He got the drive from work for free. He said it's a 7200 rpm hdd. The drive itself ONLY has a scsi uw port (i think) and NO power port so we have to use an adapter (one that has teh power and scsi ports on it)...

Anyway the drive is fatter than a normal ide drive too.....

My question here....

Will buying a ata100 7200rpm hdd be a LOT faster than the current setup? Would it slow tehcomputer down any to just change the hdd to IDE and still use the cd-rom and cdr on the scsi card?

I did a bench in sisoft and his scores were lower than an ata66 5400rpm drive....

Anyone care to comment? Thanks!

If you go with a new Maxtor, WD with the 8MB cache (fastest ata drive, faster than most 10K rpm SCSI drives) or the IBM 120GXP you will notice that it is faster. I do not recommend the IBM's though. I would get the WD, that sucker smokes...

I have tried benchmarks on sandra too, they report my 10K drive slower than a 5400 33 drive also, but Ive booted and ran from both, the 10k is quite a bit faster, and I no longer trust sandra HD benches.

[nikhsub1]

Do not use Sandra to bench drives!!! It is a known fact that it sucks at this. Use HD Tach or ATTO.

I don't think your SCSI setup will be _much_ slower. I think that adaptec is ultra2 scsi, so it's 40Mb/s, less than half of ATA/100 but SCSI has other advantages, especially if you decide to go with multiple hdd's. If you decide to get rid of it, would you be nterested in parting with the card at a reasonable price?

[Tr0LL]

Yea I know the special edition WD are pretty good, but they are too expensive, and my dad only needs like 40gb at most... they dont' make a 8mb cache 40gb i'm pretty sure... =(

well it's not just the benchmark, but I used to run teh same exact cpu/motherboard/memory in my system with teh only difference being hard drive and my system was MUCH faster. His hard drive is so loud too... everytime i open a program i hear nothing but click click click click clikc.....

i KNOW it has to be the hard drive slowing it down... has to be..... hehe...

wow, i didn't look at it that way..... 40mb/s is a lot slower than ata100... we only need 1 hdd..... no point in running multiple ones if we aren't running raid....

Um, I'll prolly still need the card to run the cdrom and cdr...

Tr0LL, I see you migrated from [H], The real troll problem they have over there finally got to you.....I only remember you as your name caught my attention while I was trollhunting there. That and I remember your SIG from there is the same as it is here. ;)

[FireMogle]

That card is Just Ultra-Wide, not U2, but you have the transfer speeds correct.

[good_sense]

That is basicly an older scsi drive and you will not be that impressed by it. If you want to see the true speed of scsi pick up a Seagate X15 36lp for just over 200 at pricewatch.

[druidelder]

Not to say that you're not right good_sense, but my opinion is that it's not worth it. For just over $200 you can get 4 20 Gig drives and an IDE RAID controller (w/ hotswap even). And the cost for the scsi drive doesn't include the new control card he'd have to get.

And in any event, I don't think he wants to spend $200 anyway.

A picture speaks a thousand words. I do have to say that I an biased though. I run a very larger SCSI setuo and love it. I just posted something in the case od section that will evplain what I mean.

[Cooler666]

get SCSI U160 or soon U320, its much faster.
by the way Sandra sucks a$$ at drive benchmarks.

[Tr0LL]

haha..... actually sss i didn't completely migrate (as in i didn't leave [H] )

I just like to post on a bunch of forums when I have questions.... that way I get more answers from different people....

Plus, they really don't have a problem with my name.... It always starts off with "nice name" blah blah in the ALL FS forums, but then it dies down and people forget the name and realize I am a good trader....

Anandtech I think was the worst.... man that crowd was sensitive... But they too are also over it..... no more thread crapping when I post sh_t.... well, maybe one or two.....

=)

Hoping to hit 100 posts here so I can start selling here too..... Actually I'm looking to buy but can't even view the damn classifieds....

I was into HD's for a while as much as, if not more than I am into overclocking now, and after numerous testing and benchmarking with different programs, I concluded, and this can be debated as heavily as the 1/5 divider topic, that my Adaptec 29160 controller running a Quantum Atlas 10K III shows visibly faster performance than most IDE drives. Remember that you can't pass judgement on one hard drive and one interface alone. There are many differences. ATA66 still isn't even saturated with the latest IDE HD out there so the bottleneck still is in the mechanical limitations of the HD. Getting data that needs to be read under the actuator arm of the drive rules. Seek times are real important at getting to the data on tha platters to be read, especially if data is heavily fragmented. In that case sequential read performance becomes more meaningless.
My above mentioned setup is noticibly faster than a single IBM 75GXP, 60GXP and 2 IBM 60 GXP's on a IDE RAID setup also, and all on a ATA100 interface. IDE is good for general use, however, being an overclocker and power user I prefer SCSI.

I am in the same boat, this is actually the site that got me started in hy hardware addiction. I need to get 100 posts here since they changed the forums around. I use to sell here when they had the old for sale area.

You can view the for sale threads but you cannot post to them, go to the deals section and in one of the stickys it has a link to them.

Also, this is the same good_sense form the Hard forums.

[Tr0LL]

haha, i see, the hard forums seem to be more packed though... altthough i still get good info here....
