When it comes to PC components, heat is usually the enemy, so frequency and performance reference records usually involve cooling liquid nitrogen (LN2). We’re not there for SSDs yet, though Gigabyte gave a heat blow to a set of heat pipes and a thick cooler in its latest offering, the Aorus Gen4 7000s Premium, and says it will never accelerate.
Or maybe the promise is that it will withstand the slowdown much longer than most SSDs. The exact wording of Gigabyte is that it provides a read speed of "7 GB / s while optimizing passive heat dissipation, which does not promise any limitations in long-term operations."
How long, exactly? Well, on the product page of the unit, Gigabyte posted a chart showing that it runs at full speed for over eight hours. The small print, however, also notes that "actual performance may vary depending on the circumstances."
In any case, the heat pipes have a coating and a nanocarbonate rope through a multilayer heat sink, with stacked fins and double-sided thermal pads that help with the effort. There is also an aluminum motherboard at the bottom of the SSD.
We haven’t tested this unit yet, but we’ll be curious to see how it comes out of Gigabyte’s lab, with and without proper airflow.
"Even without airflow, the thermal solution is able to avoid the thermal limitation that can occur in high-speed operation," said Jackson Hsu of Gigabyte he said in a statement.
The unit takes advantage of Phison's new eight-channel E18 controller, which drives 3D triple-level (TLC) cell NAND flash memory chips and single-level cell (SLC) cache . Two capabilities are offered, each with the same nominal sequential read performance:
- 2 TB: 7,000 MB / s seq. reading, 6,850 MB / s seq. write, 650K random read, 700K random write
- 1 TB: 7,000 MB / s seq. reading, 5,000 MB / s seq. writing, 350K random reading, 700K random writing
Of course, you’ll need a platform that supports PCIe 4.0 to make the most of your speed capabilities. AMD's X570 and B550 chipsets do, and so do the Intel Z590 and B560 chipsets for Rocket Lake (so do some Z490 and H470 boards, with a BIOS update). You can still run a PCIe 4.0 SSD on a PCIe 3.0 motherboard, only read and write speeds will be slower than advertised.
The units are supposedly “already on the market,” though we haven’t found any listing on sites like Amazon and Newegg. We hope they appear soon. There’s no pricing information, but as a benchmark, the non-premium version with a lower-profile heatsink costs $ 380 for 2 TB and $ 200 for 1 TB (both selling prices on Amazon).
