The concept of 'sectors' and 'blocks' is a hold over from mechanical drives, it is useful to continue to use such terms so that backward compatibility with old BIOS's, drive software and Operating systems is maintained, but 'under the hood', hidden from the operating system, it's not directly identical to how rotational drives managed such things. On a SSD, sectors can be relative, the SSD controller reallocates sectors and blocks all the time, a 'sector' number as the operating system thinks of a sector number, doesn't necessarily correlate to the same physical location on a memory chip at any given time, or over time. For example, a 'bad sector' on a physical mechanical drive has a real physical location, that is fixed (platter 1, side 2, block 30, sector 5, etc). with SSDs, even vendors disagree as to what certain attributes mean or are supposed to report when it comes to SSDs, where some of those attributes don't even make sense. To make it even more ambiguous, the SMART spec was developed when hard drives were mechanical it hasn't been updated by the industry since 2011. They may disagree what it means or predicts, and then the reality might be the engine could fail tomorrow, or it's nothing, and the engine is fine, it's just a noise but does not effect performance.

Kind of like a car 4 people may report that they hear a 'funny' noise when the engine runs, they all agree and report there is 'a noise'. The SMART specs are often vendor specific, although some over time have come to a general agreement about what it is reporting, but only as it relates to what raw data is reporting, NOT what it means in terms of predicting future health. Seagate may choose to report one attribute differently than how Western Digital chooses too, for example. SMART data is just raw data the industry and drive makers have (purposefully) left open and undocumented, many of the attributes reported, so they are open to interpretation by both drive manufacturers, and by software like Drive X that interpret the data. This is a response to below who asked why one app can report 90% health, and another 85%, but also in general to anyone using utilities that interpret SMART data, and to be careful what conclusions you draw.

Human-readable drive health indicators (attributes) representation.

Automatic drive health reports by email (automatic email reports).

Support of drive short and full (extended) self-tests.Drive overall performance rating (if drive supports this subset of indicators).Diagnostic Knowledge Base online auto-updating.Multi-tier warning system that will inform the user about deviations from the normal state of drive attributes.Interactive hints and descriptions for all health indicators (SMART attributes).Drive failure prediction based on health indicators that are closely related to SSD or HDD failures.(Most of drive utilities support only 2: 'Ok' and 'Failed')

Pre-failure state early detection - DriveDx supports 4 drive health statuses: Ok, Warning, Failing (pre-failure) and Failed.Real-time SSD and HDD health status monitoring.Different routines for SSD and HDD health evaluation.One of the key advantages of the software is that the state of HDD and SSD drives is assessed using different algorithms (DriveDx has separate sets of rules and algorithms for HDD and SSD drives), since many state indicators of HDD drives are not applicable or make no sense in the case of an SSD drive. When evaluating the state of various drives, DriveDx can use different (specialized) heuristic algorithms, depending on the drive model and even its firmware version. DriveDx is the first utility of its kind to have a real user-friendly, Mac-style interface. The application provides access to all sufficient drive-diagnostic data to satisfy any system administrator. Our drive-health diagnostic algorithms are based on recent research in the field.

status, but also analyzes the changes of all drive health indicators that are closely related to SSD or HDD failures (like SSD wear out / endurance, reallocated bad sectors, offline bad sectors, pending sectors, I/O errors, and more) and alerts the user immediately if anything goes wrong. Unlike most drive utilities, DriveDx not only monitors the drive’s built-in S.M.A.R.T. Don't worry about losing your important data, music, and photographs. Save yourself from data loss and downtime that is associated with unexpected drive failures. DriveDx is an advanced drive-health diagnostic and monitoring utility.
