> Hi there!
> Good news for all interested in hardware compatibility and reliability.
> I've started a new project to estimate reliability of hard drives and SSD in real-life conditions based on the SMART data reports collected by Linux users in the Linux-Hardware.org database since 2014. The initial data (SMART reports), analysis methods and results are publicly shared in a new github repository: https://github.com/linuxhw/SMART. Everyone can contribute to the report by uploading probes of their computers by the hw-probe tool!
> The primary aim of the project is to find drives with longest "power on hours" and minimal number of errors. The following formula is used to measure reliability: Power_On_Hours / (1 + Number_Of_Errors), i.e. time to the first error/between errors.
> Please be careful when reading the results table. Pay attention not only to the rating, but also to the number of checked model samples. If rating is low, then look at the number of power-on days and number of errors occurred. New drive models will appear at the end of the rating table and will move to the top in the case of long error-free operation.
I've just built an Arch Linux package for hw-probe. See https://github.com/linuxhw/hw-probe/blob/master/INSTALL.md#install-on-arch-linux.
The command to replenish the database:
sudo hw-probe -all -upload
One can also use a lightweight all-in-one AppImage w/o the need to install anything to the system: https://github.com/linuxhw/hw-probe#appimage
