In short: A fast NVMe drive (even non-PCIe 4.0) will greatly speed up both general drive operations and game loading and loading times – their high read and write speeds guarantee this. However, Western Digital believes there is still room for improvement in other areas and has introduced two new SSDs to its WD_Black product line to fill those gaps.

These products are the WD_Black SN850X – the successor to the Western Digital SN850 – and the WD_Black P40. Both discs are SSDs, but only the first one is designed to fit into a PCIe 4.0 NVMe slot on your computer. The P40, on the other hand, is a portable drive that supports USB 3.2 Gen2x2 connectivity and also features customizable RGB lighting.

We’ll start with the SN850X as it’s probably the more interesting product of the two. As you’d expect from any PCIe 4.0 drive, it’s very fast, with sequential read speeds of 7300MB/s. While this number is fairly standard among drives made by many of Western Digital’s competitors, the company hopes the SN850X will stand out with three unique features: “low latency, predictable loading, and adaptive thermal management.”

Western Digital did not clarify what these three terms mean in their official press release, so we will seek clarification. Regardless of the answer we get, we, as always, recommend waiting until independent tests and benchmarks are online before making a purchase decision here.

The SN850X will go on sale in July for a base price of $189. However, this only gives you 1TB of storage, so if you want the larger capacity version – 2TB or 4TB – you’ll have to pay extra.

The P40 “Game Drive” SSD, as mentioned earlier, is a fully portable device with a Windows-exclusive RGB lighting setting. It boasts 2000MB/s read speeds and a “sleek, compact and shock-resistant” design. It will go on sale this summer in 500GB, 1TB, and 2TB capacities starting at $119.
