Hello fellow Archers, I bought a new laptop that has NVMe ssd on it. I would like to install Arch on that, is there any precautions that i need to take? Also i would like to get feedback from Archers who already tried this.
Thanks in advance

I have been using arch on laptops with SSDs for a few years with no issues whatsoever. Other than the UEFI vfat partition I use ext4 for everything. It "just works" with no problems at all.

Just don't enable discards at the fs mount options and you should be fine. Install and enable the fstrim.timer so it runs once a week, which is enough.
Other than that it is like any other install, only, much faster.

Oh? Why is this? I've had both enabled for multiple years now.

On NVMe Intel recommends to no have continuous discards at the fs level:

I wouldn't install it any other way. I'm using a samsung pro ssd, install date was 3-15-2015 no issues whatsoever, on a 2009 HP 8200 elite mind you, so i'm guessing my pc will go before my ssd. Proper partition alignment is essential for optimal performance and longevity, also check this out: arch_solid_state_drive https://wiki.archlinux.org/index.php/Solid_state_drive

Just follow the arch wiki on nvme. It's probably not optimal for your specific ssd, but it's close enough.

Drive it like you stole it!
No special precautions needed for SSD anymore. The old write-limitations have all but disappeared. Samsungs 3/5 year warranties presume a 60% daily rewrite of the drive (so for a 1T drive, that's 600GB of daily writes assumed)
Like 11 sec boots from OFF to Full Desktop? They are pretty amazing compared to platter. Have large builds (like rebuilding php or KDE). Compile times now a fraction of what they were with platter drives.
See https://wiki.archlinux.org/index.php/Solid_state_drive for TRIM or fstrim configs/consideration.
Nice, Thanks a lot guys. My first job for tomorrow will be to install Arch on my laptop.
can you explain me a little detail on that rewrite stuff?, i am slightly confused

Sure, here is a good article that explains it:
How Long do SSDs Really Last? https://www.ontrack.com/blog/2018/02/07/how-long-do-ssds-really-last/
You can find many more similar articles, and if you find the old (pre-2015) ones, you will see the fear they had on exceeding the cell write limits. SSD's have improved significantly, and the cell re-write issue has gone away for the most part.
As mentioned in the article to hit the lifetime of a 250GB drive in one year, you would need to re-write 190GB per-day, every day, for the entire year.
In normal desktop/laptop use, you rarely write more than 1-2GB a day on average -- so that would translate into a 190-95 year wear-life for the drive under normal use. Even at 10GB a day, that would be a 19 year life for the drive.
So based on those figures, you would install Arch with your choice of desktop, use it for the day, delete everything and repeat the install/delete every day for 10 years and still be fine.
Excelent, thanks
Now my next immediate task will be to install Arch on Ssd and begin using it...

Hi David,

The SSD drive also reports its own personal view of lifetime remaining and other interesting statistics using https://en.wikipedia.org/wiki/S.M.A.R.T%2E.
173 Ave_Block-Erase_Count -O--CK 095 095 000 - 77 202 Percent_Lifetime_Remain ----CK 095 095 001 - 5
`smartctl -x /dev/sda', for example, can gather the data.

For the SSDs on my machine I'm using "ocz-ssd-utility" to get erase count, lifetime percentage and other SMART information, let alone that I could update the firmware, while the SSDs are used.
Oh!.. these features are also available??!!!.. great yeah..
