Internals, Testing Methodology and System Setup
The 500GB model needed four flash packages so achieve the 500GB capacity, so the PCB is a bit larger than the comically small version present in the 120GB and 250GB capacities.
The 750 EVO lineup uses 16nm planar (non-3D) flash at 128Gbit (16GB) per die. Note that there is no external DDR on the 120 and 250GB models, as that 256MB is integrated into the controller package.
Given these are octal die packages, we need four for the 500GB, two for the 250GB, and only a single package for the 120GB model.
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.
