Windows 7: WEI Score is HDD > SSD for me?

espionage724 · 16 Jan 2011

2 Laptops (Compaq 515 and Chrome CR-48)

Compaq 515
AMD Sata Controller with Drivers
WDC Sata (I guess 7200RPM) 320GB
WEI Score: 7.3

CR-48
Intel ICH7 SATA Controller with Drivers
Sandisk SSD 16GB
WEI Score: 5.9

I thought that in general, SSD's were supposed to have higher read/write speeds, and I thought thats all WEI went for on the HDD score. I think it might be considering HDD space though too, but idk.

Should these scores be right?

An SSD would get a score higher than 5.9, but only if it was on an AHCI bus, and only if it reports itself as an SSD - after that, the WEI tests would determine how high it would go. In general, I've seen SSDs score low on ICH controllers prior to ICH9 (and even then, some ICH9 chipsets were painfully slow), so an ICH7 might not be using the full AHCI spec properly and thus screwing up the score.

You could run the tests on both manually (winsat disk -v) and see what the scores are, and get an idea of why a particular SSD isn't reporting faster than a mechanical disk.

What I'd like to know is how you got a 7200RPM disk to report 7.3...

I've never seen any kind of 7200RPM go above 5.9

Give it enough cache and a firmware to try and cache everything, and it's possible. I'd like to know too, though.

idk how I got it either (installed Windows 7 x64 the other day and had 7.3, just installed Windows 7 x86 today and got 7.2)

I didn't do anything special to my drives either in terms of firmware changing n that. However it came is how it is now.

My exact HDD is a WDC WD32 00BEKT-60V5T1 SATA Disk Drive (from device manager)

@Cluberti

I suppose. Although I think that would be kind of hard on a laptop.

@Espionage
Just a standard 320GB Scorpio Black?

Congrats! You, my friend, quite possible owns the fastest 320GB Scorpio Black in all the planet

Getting that high a score with a spinning drive is something I've not seen before. Can you open an elevated command prompt and type in: "winsat disk" (without quotes) and hit Enter
Post a snip of the window when finished.

espionage724 · 17 Jan 2011

Done

I was copying something from a DVD though at the time but idk if it affected anything or not.

**cluberti** · 17 Jan 2011

Winsat disk -v actually, as we would want to see every test in verbose output

.
