Total data written under the stated warranty threshold. More capacity can raise this limit without extending the warranty period. It is not a predicted failure point.
Samsung 990 EVO Plus: Manufacturer specification · Warranty write threshold for this capacity; not a guaranteed failure point.

Check the connection before the capacity. M.2 NVMe modules and 2.5-inch SATA drives are not interchangeable. Check the host’s protocol, slot or bay, power connection and clearance. Rated speeds use different test systems; we do not turn them into a speed score or overall winner.
