I checked their store out of curiosity. Switching from 512MB to 1TB SSD: +$400 WHY? This is literally the only thing that bothers me about Apple pricing. I get that you pay for the design, I get the quirks like introducing touch bar, everything. But I don't get why upgrading from a $50 to a $100 SSD adds 400 dollars.
Because they don't use slow SSDs. The read / write speeds on the SSD in the Macbook Pro are insane. see: https://www.macrumors.com/2018/07/13/2018-macbook-pro-fastes... we are talking at least 6x what other laptops use.
The 1TB EVO Plus is $250 on newegg. Not as replacement for an existing 500GB, just retail price for the drive. The 2TB EVO is listed at $550, the 2TB EVO Plus is listed at $650.
