I still think it's a great machine, but I think all these worries about NAND dying really haven't come to fruition, and probably won't. I have about a hundred plus of various SSD Macs in service and not one has failed in any circumstance aside from a couple of battery issues (never charged and sat in the box for 2 years, and never off the charger).
1. How do you know nothing happened? Define nothing in this case. Do Mac users check and report their SSD wear anywhere?
2. Didn't the OG 256gb M1 have 2 128MB NAND chips instead of one 256 meaning better wear resistance?
As a data point: I got a 14" MacBook Pro with a 512 GB SSD the first day it was available in 2021, and I've used it daily since then.
According to the SMART data ("smartctl -x /dev/disk0"), the SSD "percentage used" is 7%, with ~200 TBW. At this rate, the laptop will probably outlive me.
NAND is still the same wearable part that regular X64 laptops have, Apple doesn't use some magic industrial grade parts but same dies that Samsung, Micron and SK ship to X64 OEMS, and those are replaceable for a reason, because they eventually fail.
The MacBook neo is for students, grandparents, travel, etc.
Hell, even if it dies after 6 years it was still a better experience than using a $500-600 windows PC and the cost comes out to ~$8/month spread over 6 years.
Do you think SSD drives are replaceable for no reason? Just because M1 mac aren't failing left and right doesn't mean their NAND won't fail.
Even though I like the NEO, I can't in good faith buy a machine with soldered wearable parts. That's like buying a car with soldered brake pads because "in 6 years average users don't feel like they need changing".
I still had laptops on my hands from 20 years ago that work fine simply because you can swap their drives with fresh ones. How many M1 mac will still be functional in 20 years?
(But it's encrypted, so you'd better have backups because you can't read it off the chips.)
Probably quite a few, MacBooks have had soldered SSD's for over 10 years now. My 2018 McBook Pro still has a perfectly functioning SSD. I still see people using 2015 and older MacBooks all the time. There is no widespread SSD failure issue after 10+ years of Apple soldering the SSD's.
For most people the SSD's are lasting longer than the useful life of the device.
I thought wear leveling worked at the page/block level, not the chip level? On an SSD, if there was a failure of an entire chip, you're still screwed.
I can see this could be a weaker spot in the durability of this device, but certainly it still could take a few years of abuse before anything breaks.
an outdated study (2015) but inline with the "low end ssds" i mentioned.

No it doesn't. Most 1TB drives are rated for around 600 TBW, so enough to overwrite the drive 600 times, nowhere near 300k cycles. If you search for specs of NAND chips used in SSDs, you'll find they're rated for cycles on the order of hundreds to thousands, still nowhere near "300k".
