Internals, Testing Methodology and System Setup

Internals

I'm leaving the heat spreading labels in place and undisturbed until I can do some detailed temperature testing (these samples came in just before the holiday weekend).

Here are the 960 EVOs next to the 960 PRO, for comparison. Note that the EVOs have DRAM peeking from behind their labels (lower right), while the PRO has only its controller and a set of four flash packages. This is made possible by Samsung stacking the DRAM on top of the controller in the PRO, which leads to part of its added expense.

The 250GB model uses 128Gbit dies, while the 500GB and 1TB both use 256Gbit dies. They do this to help maintain parallelism (therefore performance) on the 250GB model.

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 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, Gigabyte, Corsair, Kingston, and EVGA for supplying some of the components of our test rigs.
