The bottleneck is the connection, and from the speed it sounds like they switched from pcie 3.0 in M1 to pcie 4.0 in M1 pro/max. And to answer your question, you will not notice the difference in daily use.
I've a MacBook Air 2015 with an Apple SSD SM0256G and also a MacBook Air 2018 with an Apple SSD AP0128M. Both with latest Catalina installed, the 2015 is outperforming the 2018 in write speed. Disk Speed Test from Blackmagicdesign: 2015- Write: 1161 MB/s. Read: 1424 MB/s. 2018- Write: 604 MB/s. Read: 1837 MB/s
MacBook Pro; MacBook Air; iMac; Mac mini; Apple is claiming read speeds up to 3.1 GB/s for both the 13″ and 15″ MacBook Pro, and 2.1 GB/s write speed. A quick look at the QuickBench test
Here are the full Disk Speed Test results gathered by Vadim Yuryev at Max Tech. 13-inch MacBook Pro (M1/256GB) Read Speed: 2,900 MB/s. 13-inch MacBook Pro (M2/256GB) Read Speed: 1,446 MB/s. 13

MacRumors Forums member abbotsford1980 has revealed the results obtained with his new M1 MacBook Air with a 256 GB SSD in Blackmagicdesign's Disk Speed Test and also what he got with the 2019

MBP 2021 - SSD Speed Comparison - Please Contribute! From some of the YouTube reviews, it looks like there are SSD chip configuration differences between the 14" and 16" models and significant speed differences across SSD sizes. Can I please get everyone's help to run Blackmagic speed tests - only takes 2 minutes.
The MacBook is identical in design to the 2015 MacBook, but it includes a faster SSD, improved Skylake processor with better graphics, longer battery life, and a new Rose Gold color option.

Lastly, we ran the Blackmagic disk speed test to measure the 15-inch MacBook Air’s SSD performance. It achieved a 2,793 MBps read speed and 3,145 MBps write speed. Those speeds put it above the

The Retina 15" mid 2015 supports 4x lanes PCIe 3.0 speed eg. up to 3000MB/s. The early 2015 Retina 13" supports 4x lanes PCIe 2.0 speed. They do both natively support hibernation on NVMe SSD. MacBook Pro Retina 13" early 2015 (MacBookPro12,1) MacBook Pro Retina 15" mid 2015 (MacBookPro11,4-11,5) dmylrea and mikzn.
Going by the results we’re seeing in Blackmagic’s Disk Speed Test app, the base model of the M2 MacBook Air has write speeds that are generally 15 to 30 percent slower than those of the 512GB
Apple's MacBook Air M1 is still shipped with the faster 256 GB SSD. Apple's MacBook Air M1 was on sale for around 900 Euros on Black Friday. The base model is still equipped with the faster Sure, the SSD speed drop is disappointing, but it’s not a difference that the average user will notice. The 15-inch Apple MacBook Air for under $1,000 is worth getting as a late Christmas

Max theoretical is 500 MB/s since USB 3.0 is 4 Gbps (5 Gbps x 8b/10b encoding) but your point remains the same. However, USB link rate was only one of the problems mentioned in that linked thread about the USB of the first M1 Macs.

Apple aims the "Pro" at those people. Yet in some aspects, a base M1 MacBook Air beats it, due to the SSD speed. The Max Tech video shows that, in addition to major slowdowns with photo and video work, there are noticeable delays just with web browsing, due to the slower swap speed: Does 512GB SSD FIX the M2 MacBook Pro?

The dilemma arises from the fact that Apple switched to using a single 256GB flash storage chip instead of two 128GB chips in the base models of the new MacBook Air and 13-inch MacBook Pro.
The 1TB SSD in the MacBook Air we tested hit a read speed of 2692 MBps on the Black Magic Disk Speed Test (Intel), literally more than twice the 1,301.9 MBps read rate from the Intel MacBook Air. The MacBook Air 2012 is a screamer, and though the CPU-based benchmarks show about a 15-20% improvement over the MacBook Air 2011 models, by far the biggest performance boost comes from the new flash memory (SSD) that Apple is using for storage on the 2012 models. In our tests, the disk used in the newest MacBook Air models is up to 217% faster I have the Macbook Air M2 in two configurations: base and 16/512. The base model is perfectly fine for normal use, like browsing the web, email, office, that kind of stuff. File transfers are not the fastest when copying from USB sticks, but other than that you notice very little even when it starts swapping to disk when RAM is full.
