PCIe 5.0 SSDs promising up to 14GB/s of bandwidth will be ready in 2024

Most companies still haven't shifted their entire NVMe SSD lineups to use PCI Express 4.0, but PCIe 5.0 SSDs for PCs are already on the horizon.

Storage company Silicon Motion said in a recent earnings call that it expects its PCIe 5.0-capable SSD controllers for consumer SSDs will be available sometime in 2024, opening the door to a wide variety of high-performance drives from different manufacturers. SSD manufacturer ADATA teased some PCIe 5.0 SSDs at CES last month (albeit without an expected release date), boasting of read speeds up to 14GB/s and write speeds of up to 12GB/s using a Silicon Motion SM2508 controller. Current high-end PCIe 4.0 SSDs like Samsung's 980 Pro top out at roughly half those speeds.

Other reports have suggested that these PCIe 5.0 consumer SSDs are coming later in 2022, but according to the call transcript, that only applies to the latest version of Silicon Motion's PCIe 5.0 controller for enterprise SSDs-the products that end up in servers and data centers, not what typically ends up in the PC on your desk or lap. Early PCIe 4.0 SSDs for consumer PCs were also demonstrated at CES a couple of years before they became products that you could actually buy.
