Internals, Testing Methodology and System Setup
Due to some striking similarities between the new Red 8TB and the HGST He8, I've included that model in addition to the 6TB model of the Red for comparison to the prior generation model.
Just looking at the front of these drives, it becomes immediately apparent that the 8TB Red is borrowing some parts from the HGST He8.
At the rear, this becomes even more apparent.
…and even further so once disassembled (as far as I was willing to chance at least).
The same PCB layout and hardware exist on both the He8 and the 8TB Red, including the more powerful LSI controller chip seen here.
The 6TB red had an air vent hole as it is air filled…
…while the 8TB Red adopts HGST's HelioSeal technology (seen above) and has no vent.
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.
