Here is the output: = START OF INFORMATION SECTION = I can try to write it but I am not used to writing in the technical level of the wiki. Side note: Someone should definitely add all of these recommendations and put them in a page in the arch wiki. Please let me know any other tasks I can do to minimize disk usage further. I will provide more updates as time passes (for about 1 week). So far, the daily usage has been reduced rather significantly:ĭay +2 - heavy workload (lots of data analysis and saving workloads) - 6GB writtenĭay +3 - relatively heavy workload but mostly sequential writes - 3GB writtenĭay +4 - lots of sequential writes and Arch + aur update - 24 GB written! The X10 write amplification some mentioned is still there (probably because of the capacity of the drive, should have splurged more for one w/ more storage).īut fortunately, with the recommendations, the disk wear has been significantly reduced. This is very good news as my disk usage has been reduced from 20GB/hr to about 166Mb/hr (may get higher when the week gets busy). Smartctl indicates 1.1GB was written on the drive. Iotop indicates about 166mb written on the disk Change "relatime" flag to "noatime" in /etc/fstab as suggested by u/CodesWhite and u/ropidįrom a period of 6 hours with very light usage (mostly idle) of the computer, these are the results: ![]() In firefox as suggested by u/serfreeman1337 minimize any background task unless its absolutely critical for daily work enabled PSD as recommended on other forums. have "sudo iotop -ao" running on background and periodically checking on the storage users as suggested by u/billdietrich1 add the "discard" flag to the fstab file for the SSD drives as recommended by u/iLrkRddrt enable zswap as recommended by u/moshiTheNerd I will try the following options based on the recommendations and will report back in a 1-2 days regarding disk usage to see if the issue was fixed. If I have to enable more options please let me know. Iotop does not seem to show any relevant information as it showed 300-400mb written files over the past 4 hr at idle while smart data showed about a further 3GB written on the drive.įirefox is set to disable cache on SSD and SWAP usage rarely exceeds 250mb.įor the stab file I have the following options enabled: The file system I am running is ext4 on top of lvm drive. SWAP is 6GB (but rarely goes over 120MiB). Running arch linux at the latest version and the unmodified linux kernel + kde plasma.ĭrive is a Samsung SSD 870 EVO 250GB - currently, 60% of the drive is occupied. I wanted to know if I can find the programs that are wearing out my SSD and ways to prevent it. This is with the full reinstallation of windows once on it. I am using a drive rated for 150TBW so I am a bit concerned that the system (or components of the system) are wearing out my SSD excessively.įor reference, I have an equivalent windows machine and it has 40TiB written to its SSD (250GB still) after about 1.5yr of usage. ![]() I have installed Arch Linux for 2 months now and after a full installation and using my system as a daily driver, I checked smartctl and found that I have 20TBW.
