There must be something wrong with your setup nfs4,also Win2k gets much lower score than win98.


I have 2 5400 Samsung drives on a KT7-raid using a 16k stipe,I find the 16k stripe much faster than a 64k but at the expense of more cpu usage.

 

[NFS4]

Hmmmmm, I'm running Win2k Pro...and this is after I did a clean install yesterday.

Maybe I'll reformat and try the 16k stripe size.

 

[Budman]

Yes after you use the 16k stipe format using this way format x: /:32 this creates a 16k block size equal to the stripe size.

 

[NFS4]

Will Partition Magic 5.01 do this? That's what I used to make this partition in the first place.

 

[Budman]

Pqmagic will create partitions but you will have to use format.com to use the /:32 switch,But i think Pqmagic might be able to do this, i am not sure.


Use this link &amp; go read,it was very helpfull to me.

Thanks, you rule!

Just glad i could help the Ace Reporter

Just benched it... And as I suspected, the scores are way too low for this drive... this has been bugging me for a while now...

Random Access Time: 17.1 ms
R.B.S.: 38.4 mbps
CPU utiliz: 13.5%

Rig: TBird 1GHz @1.225 GHz on Abit KT7A
Single 75GXP on the ATA100 channel
installed the Abit drivers for the ATA100 controller not the MS hotfix... seems ot work &quot;fine&quot; tho. Any tips on how to tweak?

NFS4:

I could have sworn someone determined that HDTach doesn't correctly measure the performance of RAID arrays...

When you run HDTach what drives does it list as a choice to test?

AFAIK, it lists all the physical drives in the system, versus testing a certain partition(which in the case of RAID 0 would span the two drives).

So I think you're measuring just one of the drives rather than the RAID 0 array.

As for my HDTach scores...

here ya go

You may be right...it lists my WD as:

(Read-Only) &quot;Partitioned&quot; WDC273BA

Then it has a listing for:

(Read/Write) Physical Drive 0

Same here

 

[Budman]

I think i remember reading somewhere that you must turn off cd auto insert notification to fix this.

 

[sad]

Auto Insert notification has no effect at all. Those with Kt7a set PCI#2 Access #1 Retry in bios to disabled as recommended by the kt7faq and you'll get a boost of speed.

But will that work since I'm on the Highpoint controller?

 

[sharkeeper]

Please do NOT FORCE a 16 KB allocation unit size on a 30+ GB volume! This will result in far too many allocation units (clusters) and cause performance to drop. Sensitivity to defragmentation will also increase. If you want less slack, use NTFS.

Block (stripe) size and allocation unit (cluster) size are too completely different things! Don't confuse the two!!!

For a pair of 27.3 GB drives, 32KB allocation unit size is default and recommended. 16KB block size is the recommended block size for FAT32 with 32KB clusters.

If you convert your volume to NTFS (start>run>cmd: CONVERT C: /FS:NTFS) it will be using 512 BYTE (0.5K) allocation units. NTFS is more efficient with larger volumes especially if they contain of lot of files.

HD Tach in Windows 2000 tests full volume of the drive without selecting advanced size check. Only in 9x do you have to do this otherwise it only checks the first 8GB and it will also make the seeks seem a lot faster than they are.

For testing the true read and write performance of your array, I recommend using ATTO bench.

Cheers!

 

[NFS4]

Well, when I get a chance I'll convert the drive to NTFS and change the stripe size to 16k.
