ma.. il NAS viene spento spesso? Oppure i dischi vanno spesso in stand by? Non hanno molte ore di funzionamento ma hanno parecchi start-stop count.
Da quel che vedo i dischi non stanno messi malissimo, anzi.

Three values are associated with each S.M.A.R.T. attribute:
"Normalized value", commonly referred to as just "value". This is a most universal measurement, on the scale from 0 (bad) to some maximum (good) value. Maximum values are typically 100, 200 or 253. Rule of thumb is: high values are good, low values are bad.
"Threshold" - the minimum normalized value limit for the attribute. If the normalized value falls below the threshold, the disk is considered defective and should be replaced under warranty. This situation is called "T.E.C." (Threshold Exceeded Condition).
"Raw value" - the value of the attribute as it is tracked by the device, before any normalization takes place. Some raw numbers provide valuable insight when properly interpreted. These cases will be discussed later on. Raw values are typically listed in hexadecimal numbers.
