CrystalDiskInfo is not available for Linux but there are some alternatives that runs on Linux with similar functionality. The best free Linux alternative is GSmartControl, which is also Open Source. If that doesn't suit you, our users have ranked more than 25 alternatives to CrystalDiskInfo and seven of them are free and available for Linux so hopefully you can find a suitable replacement. Other interesting free Linux alternatives to CrystalDiskInfo are smartmontools, QDiskInfo, scrutiny S.M.A.R.T and openSeaChest.
GSmartControl provides a GUI for smartctl from smartmontools, allowing users to monitor and control SMART data on hard drives. It supports health inspection, runs diagnostic tests, and warns about potential drive failures, ensuring maintenance and optimal disk performance.
The smartmontools package contains two utility programs (smartctl and smartd) to control and monitor storage systems using the Self-Monitoring, Analysis and Reporting Technology System (SMART) built into most modern ATA and SCSI harddisks.
Scrutiny is a Hard Drive Health Dashboard & Monitoring solution, merging manufacturer provided S.M.A.R.T metrics with real-world failure rates.
Cross platform utilities useful for performing various operations on SATA, SAS, NVMe, and USB storage devices. - Seagate/openSeaChest
Diskscan is intended to provide the information needed to decide if a disk is good or not, be it an HDD or an SSD it is likely to be holding important data and if you have a suspicion that it is failing it is also important to know how bad is it down the road.

Works pretty alright, enough for my needs, though there's some values where it will say "pre-failure" for even the values you get out-of-the-box with a new drive, something to be aware of.
To respond to the one negative comment, all drives will show as "unknown device" IF you don't run the program with admin privileges -- even my SATA HDDs and SSDs will display as "unknown device" if I do not have superuser privs.
