Internals, Testing Methodology and System Setup
Being M.2 SSDs (and single-sided ones at that), there is really not much to disassemble here. Both models are able to attain their stated capacity with only two 3D VNAND flash packages, one DRAM package, and one SSD controller. The backs of both capacities contain no chips or other components – only a sticker. The controller is a new UBX part, but in reality this is only a slightly updated version of the controller present in the NVMe SM951 – in this case revised to handle 3D VNAND.
Our tests are a mix of synthetic and real-world benchmarks. 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 have several storage testbeds. A newer ASUS P8Z77-V Pro/Thunderbolt and an ASUS Z87-PRO. Variance between both boards has been deemed negligible when testing SATA devices. Future PCIe and SATA device testing, including this review, take place on a new ASUS Sabertooth X99, which comes equipped with USB 3.1, M.2, and can also handle SFF-8639 devices with the proper adapter.
PC Perspective would like to thank Intel, ASUS, Corsair, Kingston, and EVGA for supplying some of the components of our test rigs.
