Thing is, with Apple, even the bottom of the barrel entry devices (aka MBAs) get the high performance storage.

With Windows, you're probably still getting SATA and not even NVMe.

Windows laptops have been pretty much exclusively NVMe for years. The 2.5" SATA form factor was a waste of space that laptop OEMs were very happy to be rid of, first with mSATA then with M.2 using SATA or NVMe. NVMe finished displacing SATA years ago, when the widespread availability of hardware supporting the NVMe Host Memory Buffer feature meant that entry-level NVMe SSDs could be both faster and cheaper than the good SATA SSDs. Most of the major SSD vendors discontinued their M.2 SATA SSDs long ago, indicating that demand for that product segment had collapsed.
