Internals, Testing Methodology and System Setup


There's not much to disassemble here with these, but we can zoom in a bit:

…and flip them over:

Note that the M.2 units have no flash packages at the rear, and neither do the mSATA units. This is similar to what we saw with the 2.5" models of the same.

With the labels removed, we can see that the parts used are very similar to what was used with the 2.5" 850 EVO. Exceptions here are differing number of dies stacked within the flash packages, but for the most part these are simply a different physical PCB layout with the same number of dies connected to the same controller type.

Testing Methodology

Our tests are a mix of synthetic and real-world benchmarks. PCMark, IOMeter, HDTach, HDTune, Yapt and our custom File Copy test round out the selection to cover just about all bases. If you have any questions about our tests just drop into the Storage Forum and we'll help you out!

Test System Setup

We currently employ a pair of testbeds. A newer ASUS P8Z77-V Pro/Thunderbolt and an ASUS Z87-PRO. Variance between both boards has been deemed negligible.

PC Perspective would like to thank ASUS, Corsair, and Kingston for supplying some of the components of our test rigs.
