After writing the how to install Vista Ultimate 32-bit article a number of people have asked me how disk performance is and if I could run HD Tach version 3.0.1.0 in Vista.

Trying to install HD Tach in Vista will give you an error like this:



If you try to run the program in Compatibility mode for Windows XP SP2 as an administrator it will work.

This is how disk performance looks with HD Tach on Windows Vista Ultimate 32-bit with a pair of Western Digital Raptor WD1500ADFD 150GB 10,000 RPM Serial ATA150 Hard Drives in RAID0 with the Intel controller on the Intel D975XBX Bad Axe motherboard.



The burst speed is an impresive 243.7MB/s with the average read speed being 131.0 MB/Sec. These drives replaced my aging WD2500 hard drive that I wasn't running in RAID. The best it could get was a 168MB/s burst speed and 55.5 MB/Sec average read speed on Windows XP Pro.

dang i am going to see how well my one WD raptor X will do.

I'd be interested in seeing that also ;)

That's rather impressive, do you have an XP benchmark using the same drives in the same configuration?

Nope... Didn't feel like doing anything like that... As I mentioned in the article these were NOT review samples and are my personal hard drives... I just ran this benchmark because a couple readers wanted to see the numbers.

something is wrong because my WD500 with 16mb cache got a better score than my raptor x.

WD500: 191.3MB/s
Raptor x: 132.6

i didnt stop any programs or anything like most people would do when they run 3dmark, just ran it like normal on quick. !?!?!!??! this is wierd, what oh what could it be???

I always have a huge down spike right at 75GB

strange... I ran my scores with AIM and a few other applications like F@H, IE and FF open and still got the scores I did.

What scores are you listing? I can't tell if those are the burst speed or average read scores.

The RaptorX doesn't support SATA300, the WD500 does! That's the burst rate your comparing. Compare the sustained mb/s and access times.

random access: 10.2
average read: 77

where is sustained?

avg read would be the same as sustained, some progs call it different things

well i am guessing that is pretty good?

Fairly good, yes.

Seagate 320gb 16mb cache 7200.10 model

XP
Random Access Time 13.5ms
Average Read 64.3mb/s
Burst Speed 132.53mb/s

RAID 0 under XP
Random Access Time 14ms
Average Read 113.87mb/s
Burst Speed 1502.4mb/s.

Going by y'alls numbers I think 16mb of cache on both drives might have futzed up HD Tach, as I can't explain that Burst Speed number. That was the average of three runs and was fairly consistent though. Was using a Jmicron RAID controller on a DS3.

why is a raptor slower than that!????!?!?!?!?!?!?!?!?!?!?
im confused!!! LOOLOLOL
