FRONTPAGE Silicon Power US70 PCIe Gen 4x4 SSD Review

One of the aspects that makes AMD's X570 platform great, is the implementation of a fourth-generation M.2 storage interface. Today we're looking at an NVMe drive from Silicon Power which has been specifically designed to harness the power of the PCIe Gen 4x4. Silicon Power recently introduced the US70 to retail markets which boasts sequential read and write up to 5,000 / 4,400 MB/s. We got our hands on this new drive so follow along as we evaluate its performance and see what makes it so special.

Any feeling for why there is such a gulf between synthetic benchmarks and (arguably a much smaller number of) 'real-world use' cases?

In synthetic benchmarks is usually sequential bandwidth so you get that 3-5GB/s. Most daily operations are random where you can expect anything between ~50-500MB/s. If you look at benchmarks like CrystalDiskMark then the most important is random read and usually in lower queues (high are more for databases). Write is usually cached and the write itself is fast enough so you can't see any significant difference during work.

In benchmarks like PCMark 8 or 10, you can see about 200-700MB/s bandwidth but these benchmarks are based on popular applications.
There are no PCMark results in the review so here are some of my results made on the US70 and ASRock B550 PG Velocita motherboard.

also CDM as I was able to reach 5.6GB/s on this drive
