SCSI Help wanted

[fatty]

Ok guys I don't know but I am askin anyways I have a couple of 36 gig 320Ultra wide 10k rpm scsi hdd's and I want to know if they will help with benchmarking and also speed up the preformance of my system the only problem is a control card for these buggers is like £400 odd for the 320 one I can get a 160 card but then my hdd's will loose half there preformance but will this still be better than ide????

Go scsi man

i havent looked back ever since...

your U320 scsi drives dont even reach 160mb/sec man so nothing to worry about...

U320 means nothing...Your drive will say reach 80mb/sec...if you have two of them then youre looking at say 160mb/sec if they are in the same channel..which means an u160 channel is maxxed...BUT

youre running a 32bit pci card so its a lot lower...and these speeds are by 15K drives...

i am using a latest 15K rpm Maxtor as boot...and a 10K Maxtor for my mp3s...200gb sata for storage...

Rig is very responsive... i am never looking back

I upgraded my 29160N adaptec adapter for an 39160

which has 2 u160 channels...still i wont bother installing each hdd in a seperate channel..no point...i got the controller used for £45 so go in e bay and look for adapters

get an adaptec one..29160-29160N-19160-39160 will all do used...make sure you get an LVD cable with it cos they are expensive...

dont get an u320 card cos its a waste of money for now and i have seen the PCI E versions only tbh so far...

how many drives are we looking for?

 

[fatty]

Yeah well these 2 drives are 10k and can reach 320md/s but if I run them off my pci bus I cant even with a 320 card is that correct ???

Also will it boost benchmark scores

 

[Brwmogazos]

the drives will never reach 320 mate...not even 160...i would say no more than 60mb/sec start...

my 15K last Cheetah started at 75mb/sec iirc...and goes down obviously...

 

[fatty]

Is this because it is on my pci bus or???

 

[Leo]

Most probably.. the PCI bus has a maximum theoretical speed of 133MB/s

 

[Brwmogazos]

Is this because it is on my pci bus or???

First of all its because the drives CANNOT output even 80mb/sec...they are not fast enought mate

Even if you did you are limited by your pci...which is 120mb/sec afaik...

I mean SATA 150 drives DO NOT reach 150mb/sec do they? its more like 50Mb/sec or something..its exactly the same thing with scsi...its just that scsi has its advantages etc...

No.

dpeneds what kind of becnhmark it is, if its PCmark then ofc it will, the HDD is accessed in this

Cheers for your help guys I'm going to palm the pair of them off and get a mobo so I can clock up my 3200 as this asus thing doesn't have an agp/pci lock so new mobo an ram for me
