Internals, Testing Methodology and System Setup


The SATA connector is in an 'odd' place at the rear, but this makes sense for cases with the SATA connectors in a backplane, where you would still see the label in an 'upright' orientation.

Seagate has their own unique approach to the new enclosure style. Changes must be made to enable a true hermetic seal in order to keep the Helium where it belongs.

Here's a close up of the control and data connection contacts. These mate with a pin connector on the PCB and pass that electrical connection through the Helium sealed barrier. This is not a trivial thing to do, as there must be no possibility of the second smallest atoms from diffusing through any gaps present.

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. Our exclusive Latency Percentile test dives far deeper into IO latencies than any other simple average or maximum figures can. Direct-measured power consumption rounds out our performance results. If you have any questions about our tests just drop into the Storage Forum and we'll help you out!

Test System Setup

We currently employ a pair of testbeds. A newer ASUS P8Z77-V Pro/Thunderbolt and an ASUS Z87-PRO. Variance between both boards has been deemed negligible.

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