Internals, Testing Methodology and System Setup

Internals

First the outside:

…and now for the warranty breaking:

Note that despite the large heat sink area, only the E7 controller is mated to it via a thermal pad. Corsair's design team gets some serious points from me here because they appear to actually understand how flash memory endurance works. For those unaware, flash memory is designed to operate at higher temperatures, as the cells will wear less. The controller is the part that would thermally throttle at high temps, and is therefore the only part that needs to be directly cooled by the heat sink. Nice job Corsair!

The Phison E7 is surrounded by four flash packages (on this side), as well as half of the 1GB of DDR3. The 800GB model keeps the same number of packages while doubling the DDR to 2GB.

The power section of the PCB also has room for a bank of power loss capacitors, not needed on this consumer model since the E7 can mitigate most of the potential issues with how its firmware is coded.

At the rear, we have the other half of the DDR3 along with the remaining four flash packages.

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.
