A:Answer Just to update my previous answer: Even if the included M.2 drive was a SATA SSD, I figured it would be still be worthwhile to purchase the laptop, plus another 500GB NVME M.2 SSD (opted for Samsung 970 Evo Plus, for $129.99), to equal $2429.98, which comes out only slightly more ($30.98) than the GS75 Stealth-203 from Amazon for $2399.00 (with only a 250gb NVME SSD). Seeing as how even the cheapest 500gb M.2 SATA drives cost around > $60, I'd still come out ahead and with a bigger (and likely better performing) NVME SSD, with a SATA SSD for other storage.
That being said, I bought the laptop (and the 970 Evo Plus) and upon opening, noted that it was a Kingston SSD, but with part number SNS8154P3/512GJ. Per Kingston's data sheet (https://media.kingston.com/pdfs/emmc/MKF-815_design-in_SSD_lr.pdf), this is still a 512GB NVME SSD (albeit around 30-50% slower than an Evo Plus). Not sure if Jordan's Kingston SSD was really a SATA SSD or maybe it was mis-read/assumed to be SATA SSD.
