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.
