I am planing to buy a thinkpad X280 with the cheapest storage selection, and then upgrade SSD myself.
The cheapest storage option for X280 is 128GB SSD SATA.
Will I be able to upgrade SSD by simply replacing it with a larger and faster SSD? For example 1TB SSD PCIe-NVME?
In my understanding that M.2 SATA and M.2 PCIe-NVME are different:
M.2 SATA connects to SATA bus and using AHCI standard.
M.2 PCIe-NVME connects to PICe bus and using NVME standard. This can get much faster speed than M.2 SATA SSD.
So, it seems that if I buy X280 with 128GB SSD SATA selection, I may not be able to upgrade it to any PCIe-NVME SSD.
Please, can someone confirm this?
