I just got a m.2 WD 1TB for $104 a week ago (abeit coupon mistake by Staples).
Doesn't matter, people are stupid enough to pay this all time high Apple tax to purchase inferior computers.
If you don't understand the difference between SATA and PCIe performance, perhaps you shouldn't be arguing specs. PCIe SSDs are very expensive compared to their SATA counterparts.
You too.
If you make an effort to read the thread, you'll see that PCIe SSD prices have been compared already and Apple is charging at least double for the exact same thing. Example: https://www.newegg.com/Product/Product.aspx?item=N82E16820147692 2TB is $580. Apple charges $1400 FOR. THE. SAME. THING.
Any other questions?
