The short version

  • 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.; TrueNAS requires self-hosting on x86 hardware, no managed cloud offering; organisations must provision, configure, and maintain their own infrastructure

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.

TrueNAS

  • Requires self-hosting on x86 hardware, no managed cloud offering; organisations must provision, configure, and maintain their own infrastructure
  • ZFS filesystem entails high memory requirements (1 GB RAM per 1 TB of storage recommended), increasing costs for large deployments
  • Limited ARM/embedded support; Community Edition is primarily x86-64, reducing deployment options for edge installations
  • Clustering and replication setup requires operational expertise; misconfiguration can lead to data loss
  • Enterprise support and SLA guarantees require paid subscriptions; Community Edition relies on peer-based forums

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.

TrueNAS: What is the cost of TrueNAS Community Edition?

TrueNAS Community Edition is free and open-source. There are no licensing fees, but organisations must purchase and maintain their own x86 hardware. Enterprise Edition requires paid support contracts for production environments.

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.

TrueNAS: Can I replicate TrueNAS data between sites?

Yes. TrueNAS supports snapshot-based replication over network links, enabling disaster recovery and business continuity. Replication can occur between Community Edition systems or between Enterprise Appliances.

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.

TrueNAS: What storage protocols does TrueNAS support?

TrueNAS simultaneously supports NFS (network file system), SMB (Windows file sharing), iSCSI (block storage), and S3-compatible object storage, all from the same storage pool.

Source
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.
