Ive always had WD hard drives the last 25 years, usually the caviar black HDD never once had one fail. I run them HARD for about 2 years they are on 24/7 and I retire them as backup archives.
A year ago I bought one of the WD_BLACK 1TB SN770 NVMe to use in my home-built linux tower and another for an external usb and they have been flawless. The tower is on 24/7 and here is the terminal command to check the drive done to-day, as can be seen it's been powered on 6,662 hours the "Percentage used" is how much out of it's expected lifespan has been used so far= 0% It had read 1.63 TB and written 3.04 TB, Ive seen another drive that had 9% used and it had over 39TB written and 17,000 powered on hours, so these are very durable drives!
I will still replace it on a schedule like always, but probably 4 years instead of 2.
I use htis drive for my operating system and downloading videos, video editing, downloads etc and back up all files to a WD 4TB HDD which as always- I retire as an archive every 2 years.
This is a good way to manage your computer- use the SSD for operating systems and use a HDD mechanical drive for long term storage of files and content, backups etc. Unlike HDD, SSD drives can lose power internally over time and the power is what maintains the files on it, a HDD doesnt store content that way, they last much longer sitting as a backup unpowered.
Another important thing is keeping the drive and internals of your device COOL, much easier on a tower/desktop, heat destroys electronics. I monitor mine and nothing inside shows any warmer than 116-f
In short, the WD SN770 has been just perfect in every way
