The short version

  • Each has a real cost: 7-Zip windows-centric GUI design; native graphical interface is Windows-only, with no first-class macOS or Linux GUI applications provided; CrystalDiskInfo many USB enclosures do not pass S.M.A.R.T. commands through, so external drives often report nothing at all and users read that as a healthy result.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

7-Zip

  • Windows-centric GUI design; native graphical interface is Windows-only, with no first-class macOS or Linux GUI applications provided
  • Linux and macOS support primarily through command-line tools; no native file manager integration on these platforms
  • User interface design is dated compared to modern alternatives; visual feedback and UX polish lag behind commercial archivers
  • ARM64 support limited to Windows; no ARM64 build for Linux or macOS despite growing ARM adoption
  • No built-in cloud storage integration or synchronisation; cannot extract directly to Dropbox, OneDrive, or Google Drive

CrystalDiskInfo

  • Many USB enclosures do not pass S.M.A.R.T. commands through, so external drives often report nothing at all and users read that as a healthy result.
  • It is Windows only, and there is no central console, so checking a fleet means visiting each machine or scripting an alternative.
  • A good status is not a prediction: drives fail suddenly with clean attributes, and treating the summary as an assurance leads people to skip backups.
  • The Shizuku edition ships anime artwork and voice packs, which is unsuitable on company machines and is often downloaded by mistake because it is the more visible option.
  • Vendors define raw attribute values inconsistently, so the same number means different things on different drives and the detailed view needs interpretation to be useful.

Answered from the vendors’ own pages

7-Zip: Is 7-Zip free to use commercially?

Yes. 7-Zip is licensed under GNU LGPL with BSD 3-clause portions, permitting commercial and personal use without fees, registration, or restrictions.

Source
CrystalDiskInfo: Can I use it in a business?

Yes. It is MIT licensed with no personal-use restriction, which distinguishes it from several other free Windows utilities.

7-Zip: What file formats does 7-Zip support?

7-Zip natively creates 7z archives and supports packing/unpacking ZIP, GZIP, BZIP2, XZ, TAR, and WIM. It can unpack 30+ additional formats including RAR, ISO, DMG, and VirtualBox disk images without requiring external tools.

Source
CrystalDiskInfo: Why does my external drive show no data?

Most USB bridge chips do not pass S.M.A.R.T. commands through. Connecting the drive directly by SATA or NVMe usually reveals the attributes.

7-Zip: Does 7-Zip work on macOS and Linux?

Yes. 7-Zip operates on Windows, Linux, and macOS. Graphical interfaces are optimised for Windows; Linux and macOS primarily use command-line tools. Port and third-party GUI applications extend functionality on these platforms.

Source
CrystalDiskInfo: Does a caution status mean I should replace the drive immediately?

It means an attribute has crossed a vendor threshold, most often reallocated sectors. Back up now, then decide. It is a warning, not a countdown.

CrystalDiskInfo: What is the difference between the editions?

Function is identical. The Shizuku edition adds themed artwork and voice packs; the standard edition is the plain one you want on a work machine.
