We’ll likely learn more about how efficient these drives are early next year at CES 2024 or not long after. So if you’re not keen on a PCIe 5.0 drive due to fans and bulky coolers, you might not have long to wait for better options. Just don’t expect them to be cheap when all signs are pointing to SSD price increases next year.
Then you presumably just buy one that satisfies that requirement and not an overkill Gen 5 NVME.
