I use this hard drive as my secondary drive, and store mostly games. So naturally I was worried about the 5400rpm and the 64mb buffer cache of this drive. (all my drive in the past has been 7200rmp). But it turns out my Crystal Mark scores shows the WD Blue 1tb 7200 64mb cache, actually had worse read and writes than my 4tb. Great drive for a great price and 2-year warranty from WD. Stay away from amazon as they will sell OEM drives with no warranty.

For 4 TB, this is a great everyday all purpose hard drive. I bought it for my pictures and music storage, and it was super easy to install on day one. Just plugged in to my windows 10 machine and formatted it. Then ready to use! Don't forget to format it under disk managment, without that you wont see it come under My PC.

Expanded my Win 10 desktop. I use this BLUE drive to back up my BLACK boot drive and backup photos . This is a BLUE drive and runs cooler and has a decent speed with no perceptible noise. The black drive I use for booting is noisy, runs warmer but faster.

I've had WD hard drives for years, they've never failed me and this one is no exception. Great price for the size, was easy to install, Windows 10 recognized it right away (had to format it of course).

Using as a back drive for storage. Lots of space for storage and works fast enough for my purpose. I run the OS off an SSD to make it run faster overall.
