Western Digital 320GB BEKT vs 320GB BEVT

Western Digital Scorpio WD3200BEVT

• Unfortunately my drive has failed so no direct comparison will be available. However I will run pretty commonly available tools (No Downloads required), to get the benchmark score so you can compare it to the BEVT in your laptop.

• 5400 RPM
• SATA 3 Gb/sec
• 12 millisecond seek time
• 8-megabyte buffer

Western Digital Scorpio WD3200BEKT

• 7200 RPM
• SATA 3 Gb/sec
• 12 millisecond seek time
• 16-megabyte buffer

First lets look at the built in test results for the Nvidia harddisk controller

Go Device Manager, under IDE controller you should see a Nvidia NForce SATA controller if you didn't then you did not install the SATA driver.
Go Nvidia website to download and install their Storage Controller Driver.

Test 1

Test 2

You can roughly gauge the performance by looking at the scores.

Next we run the WinSAT Detailed Test for more information how to run it see this post.

Note that I am running on Windows 7

The values in red is what we are interested in.
So do the same on your machine to compare the results.

DirectX Update

I don't know how this happened.
But after I updated my DirectX Software and reran Windows System Assessment Tool
My Memory Score increased !

The Webinstaller Link
The Redistributable download Link

My New WINSAT Score

My Old WINSAT Score

The Memory has increased by 0.1

Acer Aspire 4530 WEI

This is the Windows Experience Index score for my Acer Aspire 4530
Not bad for a value laptop =)
How about yours?

You should set Power Plans to High Performance to get a accurate score
You should also know the performance will vary according to RAM configurations as 9100M G is an integrated graphics which utilises System RAM

PS:To get higher WinSAT Scores Change the Windows Theme to Classic Theme and Rerun Windows System Assessment
