Corsair Neutron XT SSD Preview

Desktop Test System





Lenovo T440 - Notebook Power Testing with DEVSLP and Windows 8.1 Pro



Nearly all of the performance tests run on the desktop system but we use a Lenovo T440 to run the power tests. The T440 is the latest addition to our client SSD test lab and allows us to test the notebook battery life offered by an SSD with advanced features like DEVSLP enabled.

After a decade, I'm finally ready to move past ATTO to look at initial performance with different block sizes. The new tests you see above use incompressible data, a topic will talk about later in this review, and precondition the drives due to the length of each test and the order we test in. Garbage collection is active in these tests since we start with two full drive writes with sequential data before measuring performance.


The Corsair Neutron XT is represented on the chart by a red line with a slight glow. In many tests, the Neutron XT is competitive with the other products, especially the other top tier products on the market, Samsung's 850 Pro and SanDisk's Extreme PRO. Since this test actually has some preconditioning involved, the 850 Pro actually shows the worst performance in nearly every test. The 850 Pro uses very aggressive garbage collection and the background activity increases latency under the heavy workload.
