With the introduction of new SSDs Samsung puts forth a strong claim to the leading position on the consumer-class SSD market. Besides manufacturing all of SSD components and thus having more elbowroom for price maneuvering, the company has got a very high-performance platform which combines a triple-core MDX controller and 21nm Toggle Mode 2.0 flash.
Of course, it is the senior model, Samsung 840 Pro, which provokes the sensation. Based on MLC memory, it is definitely better than previous leaders in terms of speed. Thanks to its high-speed controller, it offers an impressive random read speed even at a short request queue, so it is superior to other SSDs under real-life desktop or notebook loads. Our testing shows that the Samsung 840 Pro is the fastest SATA 3 SSD available now. Added to this are its 5-year warranty, integrated AES-256 encryption and excellent software support. Of course, the Samsung 840 Pro is not cheap, but it is no more expensive than other flagship SSDs.
The inexpensive Samsung 840 doesn’t look that effective in diagrams in comparison with its senior cousin. It is limited by its cheap high-latency TLC flash but its MDX controller makes up for that to some extent. As a result, the Samsung 840 is quite competitive in everyday applications against popular midrange SSDs with MLC NAND flash, such as the OCZ Vertex 4, Plextor M5S and Corsair Neutron. Thus, the Samsung 840 features a most attractive price/performance ratio. Its TLC memory has a service life of 1000 program/erase cycles, which makes it less long-lasting than other SSDs. Even though its warranty period is 3 years and there are no reports of it failing too soon, some users may shun it for that reason. That’s why we wouldn’t make any recommendations about it. We can only note that it is quite an interesting SSD with peculiarities of its own.
To help you with your choice, we offer the following summary table with test results of various SSDs. It contains basic hardware information about SSDs we’ve tested so far and allows to quickly determine the general position of a particular model among its competitors in terms of relative performance.
