Continuing the discussion from Microsoft committed to Right to Repair, will Apple follow suit?:
Thought this might be of interest, from a Stack Exchange post:
You can install smartmon tools using homebrew:
brew install smartmontools
Use diskutil to get the device name of the drive you’re interested in:
(base) john@Johns-MBP ~ % diskutil list
/dev/disk0 (internal):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme 1.0 TB disk0
1: Apple_APFS_ISC 524.3 MB disk0s1
2: Apple_APFS Container disk3 994.7 GB disk0s2
3: Apple_APFS_Recovery 5.4 GB disk0s3
/dev/disk3 (synthesized):
#: TYPE NAME SIZE IDENTIFIER
0: APFS Container Scheme - +994.7 GB disk3
Physical Store disk0s2
1: APFS Volume Macintosh HD 15.3 GB disk3s1
2: APFS Snapshot com.apple.os.update-... 15.3 GB disk3s1s1
3: APFS Volume Preboot 544.3 MB disk3s2
4: APFS Volume Recovery 1.0 GB disk3s3
5: APFS Volume Data 657.3 GB disk3s5
6: APFS Volume VM 4.3 GB disk3s6
/dev/disk4 (disk image):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme +88.6 MB disk4
1: Apple_HFS Duplicacy Web Edition 88.6 MB disk4s1
Then run smartctl to get detailed SMART drive stats:
(this area is long, and scrolls)
(base) john@Johns-MBP ~ % smartctl -a disk0
smartctl 7.2 2020-12-30 r5155 [Darwin 20.6.0 arm64] (local build)

I’ve had my M1 MBP since January 2020 (I think), and used it lightly.
The interesting bits are:
Critical Warning: 0x00 That’s always a good thing.
Available Spare: 100% Also good, none of the spare blocks have been used.
Percentage Used: 1% Although this is interesting.
Data Units Written: 68,796,232 [35.2 TB] Life span varies, and could be 600TiB written (or more), so extrapolating: (600 / 35) * 9 months = 154 months. Not something you’d make a wager on though.
Unsafe Shutdowns: 20 Probably the number of kernel panics I’ve had.
So all in all, no errors and no need to start using the spare blocks.
