The latest Tiger Lake laptop is Intel’s first mobile device with PCIe 4.0 capabilities.However, while we expect to see many models with fast PCIe 4.0 storage, you are unlikely to see many touted The best solid state drive usable. Although they can provide excellent performance with higher bandwidth interfaces, most of these PCIe 4.0-capable laptops are equipped with PCIe 3.0 SSD, or worse, are limited by the M.2 slot connected to the PCH.That means they Runs at PCIe 3.0 performance, even if you upgrade to a faster SSDTherefore, we began to consider whether upgrading Tiger Lake laptops to faster storage is worth the trouble and cost.

Phison lent us a 2021 Dell Inspiron 5502 equipped with an 11th generation Intel Core i7-1165G7 to unleash full PCIe 4.0x 4 performance through one of its M.2 slots. Unfortunately, this advanced laptop is actually not equipped with a PCIe 4.0 SSD that can saturate the bus. Instead, it is equipped with an SSD like Silicon Motion’s P34A60, which is a DRAM-free and value-oriented PCIe 3.0 SSD that cannot be compared with the mature PCIe 4.0 SSD.
