Users of the first generation of PCIe 5.0 solid state drives are discovering that these need proper cooling. The previous generation was happy with a passive heatsink at most, but doubling the data rates is putting too much heat into the chips. Running too hot means thermal throttling, cutting performance severely. Putting on too much pressure can lead to the SSD shutting down altogether, potentially resulting in data loss. Corsair and others will sell you naked SSDs, but the advice is that you will need to fit a chunky heatsink, and make sure there’s a fan running. One advantage of SSDs has always been their silent operation, but with PCIe 5.0 that’s no longer advisable.
