OVERVIEW | AORUS NVMe Gen4 SSD – Paperwight Speed Demon

One of the key selling points of having a third generation Ryzen processor and an X570 chipset motherboard is having the PCIe 4.0 functionality at your fingertips. Right now, the most practical use case for PCIe 4.0 is for storage devices and AORUS has released the first ever PCIe 4.0 NVMe Gen4 SSD that we managed to try out the 2TB version ourselves.

The AORUS NVMe Gen4 SSD has a thick copper heatsink for cooling but you won’t be able to fit it your motherboard’s own M.2 heatsink when you have it installed. Fortunately, it’s practically easy to remove the AORUS heatsink if you don’t want it.

Performance testing

We decided to run a couple of disk benchmarks to test the performance of this SSD and we are impressed with the results.

Test system:

  • Processor: Ryzen 5 3600X
  • Motherboard: X570 Aorus XTREME
  • Memory: G.Skill Sniper X 3400mhz
  • Graphics card: Galax RTX 2080

Tests performed

  • Anvil’s Storage Utilities – Test Size: 1GB
  • AS SSD Benchmark – Test Size: 1GB
  • ATTO Disk Benchmark – I/O Size: 512B to 64MB, File Size: 1GB, Queue Depth: 4
  • Crystal Disk Mark – Test Count: 5, Test Size: 1GiB

As you can see on the screenshots below, the AORUS NVMe Gen4 SSD was able to have an impressive write speed of up to 4200mb/s and a read speed up to 5000mb/s.

The Science of your Purchase

We are in the early stages of PCIE 4 functionality – We can’t say where we’ll be in optimizing the technology with other features along the roadmap of other product developments.

Today, to be able to truly maximize the product offering of the X570 chipset and the PCIe 4 integration, we have to do with that we have that is the support for this new generation storage solutions.

Purchasing such options does put us at the decision phase as we ponder if it would truly be an upgrade. Performance wise – it is an upgrade; and if you ask us it is quite a jump from the ceiling speed of 3500mb/s that was the top standard of NVMEs floating around the market.

Practicality wise – the size options for the AORUS SSD is what was questionable which stands with an option for 1TB and 2TB. A huge size that is comparable to normal storage application and use. AORUS has included this in the product development road of this SSD and hinted that it may release smaller capacity versions in the future such as 512GB and 256GB.

AORUS had all the good intentions to drop the Gen 4 NVME and a product development plan to look after the foreseen issues such as options for smaller capacity versions. It is a good buy today and in the future if you decide to get a smaller capacity one.

Final thoughts

This Aorus SSD has shown a lot of performance when it comes to it’s read speeds rather than write but given that we are still in the early days of PCIe 4.0, it would be interesting to see how the these storage devices mature over time.

On the other hand, we think it would make sense to hold off any purchase of PCIe 4.0 SSD’s as of the moment. Right now, the prices of mainstream SSD’s are dropping and their read/write performance are still relevant as of 2019.
