Internals, Testing Methodology and System Setup

Internals

Outside:

It appeared that Samsung had dropped the copper-layered heat-spreading labels used on the 960 EVO and PRO in favor of a package heat spreader, but wait a sec, let's look at the backs:

It may be easier to see from an angle:

Sure enough. Copper layer on the rear label. This makes sense given that the rear label makes significantly more contact than the front label. One more comparison shot:

They have also moved away from the 960 PRO specific method of stacking the DRAM within the controller package. This might be due to the nickel-plated packaging requirements for the new Phoenix controller (also used in Samsung's Z-SSD). This brings the 970 lineup back to basics, without the complication of two separate PCB types and controller packaging, which should hopefully help Samsung be more cost competitive in the future.

Testing Methodology

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. We have developed a custom test suite as off-the-shelf tests just no longer cut it for in-depth storage testing. More details on the next page. 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 a Gigabyte Z170X SOC Force (for RAID testing). Future PCIe and SATA device testing, including this review, take place on an ASUS Sabertooth X99, which comes equipped with USB 3.1, M.2, and can also handle SFF-8639 (U.2) devices with the proper adapter.

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