It may be fine, but the disk speeds on the latest Macs are amazing. There is no laptop that matches that I'm aware of.

Unless I'm missing something: Huh? Apple is just using regular NVMe/M.2 SSDs, nothing special about them. Lots of laptops have the option for M.2 NVMe SSDs, and most newer desktop motherboards have the slot for it.

A lot of laptops that advertise NVMe SSDs are using inferior TLC-based or non-Samsung SSDs to check that box. Apple's not alone at the top (especially when aftermarket upgrades are taken into account), but they have been pretty good about using the fastest PCIe SSD that money could buy at the time of release.

True, but I don't think that's common near the price point of Apple hardware.

It's also not uncommon in the "lower ranks". I just bought a 800 € ultrabook with a 256 GB Samsung PM961 SSD (NVMe, 2.8 / 1.1 GB/s) and the Skylake i7 for example.

Also, don't forget that one can buy a Samsung 960 Pro in a machine that comes with a cheaper SSD but uses a standard M.2 NVMe slot, and ditch the original SSD, for cheaper than any of Apple's capacity upgrades.

The Samsung PM961 is not top of the line. It's one of the more recent TLC-based alternatives that shares a controller with the top of the line products, but it's inherently slower and less power efficient.

The latest MBP leapfrogged the rest of the market again

Specs seem to be 3.1 GB/s read and 2.1 GB/s write speed. While that's faster than most M.2 SSDs, equally-or-better specced SSDs are already on the market, eg. Samsung 960 Pro (3.5 / 2.1 GB/s).

It's kinda disingenuous to say that the 960 Pro is already on the market when it's not for sale yet.

Just as a sticking point, Apple's SSDs are not, and have never been, regular NVMe or M.2. They have always used their own stupid custom proprietary connector, despite basically implementing most of the relevant standard (NVMe/PCIe/SATA).

Assuming you are using Linux and you have gobs of RAM, the 15-20% difference you will see between an mSATA SSD and NVMe is negligible for most common workloads/applications, as you will be likely pulling things from the RAM cache. The Linux box I'm writing this on only has 8 GB RAM and my whole system is only using 1.1G, leaving 6+ GB RAM as a RAM cache for read files. On 16 GB systems it's even better.

Umm, they're using PCIe SSDs so you can just go get another laptop with one. Like this ASUS: http://amzn.to/2eGg2KM

> 512GB SSD with transfer speeds of 1400MB/s and 16GB DDR4 RAM
