The short version

  • Only CrystalDiskInfo has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; VTScada licences are per installed PC rather than per system, so a redundant pair plus a development machine means paying three times unless you buy the discounted multi-server bundles.
  • They diverge on capability: CrystalDiskInfo covers S.M.A.R.T. reporting, VTScada covers Automatic version control.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

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.

VTScada

  • Licences are per installed PC rather than per system, so a redundant pair plus a development machine means paying three times unless you buy the discounted multi-server bundles.
  • Thin client licensing is by concurrent connection and is priced steeply at scale: unlimited thin clients on a 50,000 tag system costs 59,395 USD on top of the base licence, more than the base licence itself.
  • It is Windows only with no Linux or container deployment, which rules it out of modern edge and virtualised architectures that other SCADA products now support.
  • SupportPlus at 15 percent of the original software price must be maintained continuously; if you let it lapse you cannot simply resume, and reinstatement is negotiated rather than published.
  • The scripting environment and the integrator pool are both proprietary and small, so finding a second-source integrator in a region where Trihedral has thin coverage is genuinely difficult.

Answered from the vendors’ own pages

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.

VTScada: Is VTScada perpetual or subscription?

Perpetual. Licences are one-time purchases per installed PC, with an optional annual SupportPlus contract at 15 percent of the original software price.

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.

VTScada: Are drivers extra?

No. Standard and proprietary I/O drivers, the historian, trending, reporting and security are all included in the base licence.

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.

VTScada: What does support actually cost?

Annual SupportPlus is 15 percent of total software purchase price. Adding 24/7 emergency support is a further 5 percent with a 1,540 USD minimum.

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.

VTScada: Does it run on Linux?

No. VTScada is Windows only.
