T480 could be ordered with one of three types of disks:
- 2.5" wide HDD SATA3 7mm high.
- 2.5" wide SSD SATA3 7mm high.
- M.2 2280 SSD PCIe NVMe.
First two require a different cable and adapter, than third one. Moreover, you can order a 128GB M.2 2242 SSD PCIe x2 NVMe disk instead of LTE modem. If you order a HDD, you can also order an 16GB Intel Optane PCIe NVMe cache disk (installed in LTE modem port).

Hello, it is not limitted to SATA speeds. The PCIe for storage has 2 instead of 4 lanes. This means that the speed is limited to 1800/1500 read/write. Clearly not the same as 550/500.
Having said that, unless you do some very specific work with your laptop (editing massive 4K videos, running databases or multiple VMs), you will not feel the difference in everyday life. This is not because it is limited to 2x. The difference is not felt even between SATA and 4x PCIe. This is because the SATA SSDs are blistering fast for normal use already.
So whether you spend money to go PCIe or stay with SATA has to do with your use. If you need it, then you will see a difference and it's worth the extra. If you just want it to be "high end" then you won't see much difference.
