Pros: Fast and reliable. Have had several SSD's and the Samsung 840 EVO's have been the fastest i have ever seen. Use them in my desktops and laptops across my company and my customers who demand performance. They are a very solid and dependable drive for any purpose.

Cons: Cost. But that's working its way down.

Pros: Simple to use, easy to read. Can test virtually every power connector coming off of a modern power supply

Cons: Have to have the 4-pin cpu connector plugged in or it beeps the whole time its on. The board was secured with a single screw to a plastic anchor that ran through the case. Made for a poorly secured board and when you would unplug a cable, the bezel's on the sides would pop off due to the force.

Overall Review: i opened this up and looked at what could be done to secure the board in place, and the anchor runs the entire height of the case. I pulled the board out and drilled a 3/16th's hole on the front of the case exactly opposite the original hole. Used a screw from an bad power supply housing, which fit perfectly. Now with the anchor secured on the front and back, the board does not move at all in the housing and the bezel's stay in place when connecting/disconnecting cables to test. Honestly, i should not have to modify this in order to make it a stable device. But what do you expect for something like this i suppose.

Pros: Plugged in, worked fine. Not much else to say

Cons: none so far
