The data a biz [or you] has stored slowly goes away -- storage media degrades over time, some more than others, e.g. tape, Blu-ray, & SSDs. You can find ratings on expected data loss for many SSDs for biz or corporate use. Biz should, along with recording their own stats, monitor the performance of storage hardware, take into account published data re: longevity, frequency of failures, & what kind of failures, and ultimately create a maintenance program or practice regarding their data storage including hardware. That program might include hardware checks or replacement at specific times during a drive's lifetime in use, depending on the brand, model, & history of prior test results. Put simplest, maybe replace a certain brand & model drive when it hits the 2 year mark, because your records show that brand & model drive usually lasts you 25 months.
DiskPulse Pro [& similar] is a tool that can be used to detect & measure data loss, e.g. if a specific drive has started losing data, & how much, to help determine if it needs to be monitored more closely or replaced. It could obviously have other uses, but monitoring the integrity of data stored long term is its thing. If a corporation has it's accounting data for a past year stored on however many drives, I'd think that data usually isn't going to change or be altered under normal conditions, so any change in those files would be a red flag.
Someone commented on the GOTD download page that they'd recorded all sorts of changes from an update. Yeah, I'd imagine they would. If you wanted to monitor say every read/write to a drive or drives, you'd want to use a tool or script that would record those to a easily managed searchable log file [or files], similar to use & analysis of other server logs. My understanding of apps like DiskPulse Pro is that they're mainly to inform you that there was some sort of change when & where there should not have been, e.g. when data on a SSD is going away on its own because the storage media failed or is failing.
