Same drive looks like. Why is yours so much slower? You got a older mobo with a slower chipset or what?

I'm confused. Your CPU is faster so that shouldn't be a problem. Memory shouldn't be a issue either. It seems to be seeing it as udma6 which is as it should be. Why it is not any faster, not sure.

HP - Raid Config - SAS drives

Good morning everyone,

Almost 2 years from my first post here? *smile*

OK.. this time - a dual HP server - with SAS drives in Raid5 configuration:

zidox1:/ # hdparm -tT /dev/cciss/c0d1p1

/dev/cciss/c0d1p1:
Timing cached reads: 24640 MB in 2.00 seconds = 12334.30 MB/sec
Timing buffered disk reads: 1084 MB in 3.00 seconds = 361.01 MB/sec

====

If you need more info on the hardware - I can provide it.

Cheers,
Alex

That's pretty swift.

Just tried it with Cygwin, on XP.

Code:

$ /usr/sbin/hdparm -t /dev/hda



/dev/hda:

 Timing buffered disk reads:  102 MB in  3.11 seconds =  32.80 MB/sec

A teeny bit faster.

I just put my new raid array together today and I got

Timing buffered disk reads: 660 MB in 3.01 seconds = 219.36 MB/sec

Woot! :) 4 - 500gb SATA2 drives in RAID 5 config. Using mdadm.

Strange results.. Might be worth checking the cabling etc.

I was even thinking if he has a old 40 wire IDE cable. Thing is, it is seeing it as udma6 and in my experience it won't do that with a old 40 wire cable.

That is odd tho. It should be faster than that. Getting about the same results with a different OS makes me think cable or hardware too.

:) :) :)

I don't really know much about the hardware side. It seems to be performing OK, no obvious faults. But, as you say, it is slower than the same HD in another machine. I've had it about 3 years, and have been thinking lately about getting something with better specs. More RAM, bigger capacity HD.

I would check on that cable. It's not a hard thing to check. You just look at it and see if it has 40 wires or 80. I can tell by just looking at them but the 80 wire is a lot smaller wires and the 40 wire one is larger. The cable itself is the same width, just the wires that are different.

Before I upgraded, I would check that. May be a $10.00 or $15.00 fix.

:) :) :)

Thanks, I'll check the cable tomorrow, see which it is. It wasn't the speed that was making me think of upgrading. I want more RAM to do justice to virtualisation, and more HD capacity to get a few distros on, still haven't tried Arch, Gentoo, or LFS & BLFS.

Here is my speeds from my Intrepid Server (Wifi/Router/NAS box)

Mainboard: Abit-AN68SV. CPU: AMD LE-1250 RAM: 1-Gbit 667mhz.
Im very pleased with the speed of the F1 disk. I copyed a 10GB (10*858*030*332 byte)file from sdb to sbc in 99.8 sec. ~103 MB/sec.

Good morning everyone!

Ok.. almost 5 [five] years now! Time flies.. and I think it's a good opportunity for a new upgrade/test!

hdparm -tT /dev/sda1

/dev/sda1:
Timing cached reads: 11602 MB in 2.00 seconds = 5807.70 MB/sec
Timing buffered disk reads: 500 MB in 1.10 seconds = 452.67 MB/sec

This is the 3rd test.. more to come!

Cheers,
