Product ReviewsWestern Digital Green 3.9TB 5400RPM

Reliable large capacity drive for storage.

I have a number of these "Green" drives and they work great for large capacity storage, in conjunction with an SSD for a boot drive. They are relatively energy efficient, cool and quiet. They are reasonably fast for a mechanical drive, but can't match the speed of the faster and more expensive "Black" drives, etc. The "Green" drives have now been discontinued and have been replaced with "Blue" drives.Read full review...

It is...

Quiet, Fast & Reliable. and the 4TB size and great for my Video Library...I have 4 of them.

Great backup drive.

Just formated and speeds away with heavy loads. Might be a great 4 or 6 raid drive for a box. Operating temperatures are low.

these are great for virtually any storage usage

They run very cool...use very little energy...are very dependable...perfect for storing whatever.
I also have a number of WD Caviar Black, and these seem to me to be just as fast...but cooler running.Read full review...

Best of breed.

I have now purchased 12 wd red and green 4tb drive over the last year and am replacing 6 2 tb drives i have had for over 9 years running all the time. I have not had a failure. The 2 seagate drives i purchase only lasted 2 years between them and had surface flaw.

I will only purchase WD drives for my NAS units. The green drives i had to change the bios to slow the head settle time. The red drives come that way.Read full review...
