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.

SSD manufacturer ADATA took some PCIe 5.0 SSDs to CES last month and showed that it could manage 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.

While there have been rumours of PCIe 5.0 consumer SSDs are coming later in 2022, it would appear that the latest version of Silicon Motion's PCIe 5.0 controller for enterprise SSDs.

Early PCIe 4.0 SSDs for consumer PCs were also demonstrated at CES a couple of years hitting the consumer market. For 2022 and 2023, Silicon Motion will continue to focus on those PCIe 4.0 SSDs. Budget SSDs like Western Digital's WD Black SN770 SE are only beginning to transition to PCIe 4.0.

Silicon Motion also says that PCIe 4.0 SSDs have only become common in pre-built PCs within the last year because of "extensive verification and testing" requirements.
