No mention of insanely fast NVMe on M1?

Isn’t that only because they cheat and make fsync an noop though?

The T480 I got came with a Samsung NVMe w/ 256GB capacity - I don't write enough to disk to notice the difference relative to my MacBook Air M1.

> No mention of insanely fast NVMe on M1? It's only insanely fast compared to previous Macs. The commonly found Samsung 970Pro SSDs were doing read/write speeds up to 3,500/2,700 MB/s since 2018. And newer SSDs run circles around those speeds (like 10GB/s or more of read/write).

Because it's not insanely fast? The 256GB is pretty slow (why is that even an option though?) the higher capacity ones have are considerably worse compared higher-end WD or Samsung2 SSDs and you can get a 1-3TB one for around $100-$300...

The lenovo also has NVMe. I use different machines, one with a regular sata ssd, 2 with NVMes and my work environment is on an NVMe enclosed in an usb3 to nvme box that I use on any of these 3 laptops. Honestly outside of a benchmark the difference is only really noticeable on the nvme + usb3 enclosure when it can freeze the whole desktop for a few seconds when doing a large copy. Difference between sata ssd and nvme exist but only if you are timing your jobs completions, not really on regular day to day use. Difference is definitely much smaller than the spinning to solid state. I guess this is pretty much the same between the m1 NVMe and a regular PC NVMe.

Non-replaceable, when it goes bad then might as well throw away the laptop. Speed is also, what, 3GB/s?, I'm getting 7GB read, 5GB write speeds on my laptop.

You mean infamously slower? Wasn't that what the whole base model discussion was about? https://www.tomshardware.com/news/macbook-pro-m2-pro-mac-mini-ssd-downgrade https://www.tomshardware.com/news/macbook-pro-m2-pro-mac-min... The upgraded speed is then perfectly adequate, but slower than a standard nvme ssd by a factor 3 or so. What you are probably thinking of is the RAM instead, which is standard lpddr5 ram but integrated into the chip (i.e. the RAM is not faster, but bandwidth is better). At absolutely ridiculous markup though.
