The PCIe 6.0 specification was ratified in early 2022, but its actual implementation was delayed for years. Now, the spec is almost ready, with the first PCIe Gen6 platforms finally approaching, as are actual storage devices. Micron was the first with a PCIe 6 SSD in mid-2025, and Samsung caught up this July. Meanwhile, independent makers of SSD controllers — Marvell, Phison, and Silicon Motion — are also prepping their PCIe 6 SSD platforms.For a full roadmap of PCIe, you can check out our dedicated page. In this article, we'll specifically focus on PCIe 6.0 controllers and devices and how they're soon becoming commercial products. For additional reading, you can also find our interview with Solidigm VP Avi Shetty, which covers the subject of PCIe 6.0 SSDs.
The current state of PCIe 6.0 SSDs and controllers — Marvell, Phison, and SMI prepare controllers, as drives finally come to market following years of delays
PCIe 6.0 SSDs are almost here. We review the state of PCIe 6.0 SSDs and controllers from Micron and Samsung, as well as controllers that can handle 2 Petabyte-class SSDs with 28 TB/s read/write speeds.
