Pros: Easy to install and immediately recognized by the Acer Aspire Desktop. Before adding the RAM, the machine was slow to display web pages, and really slow when using my sons favorite application "LEGO Digital Designer". After installing the RAM, web pages literally POP onto the screen, and LDD works without any hesitation or slowness.

Cons: I wish that I had bought TWO of them.

Overall Review: Great value.

Pros: Fast enough, enough RAM, big HD (1TB). Runs the software that the proud owner needs it to. Very light weight.

Cons: I little concerned about quality due to the Very Light Weight of the machine.

Pros: Quiet. Great price!

Cons: None.

Overall Review: Replaced a failing Samsung 500GB, using the Seagate Disk utility. Worked Very Well, made it easy to replace the old drive with a new one!
