Hard disk health and reliability analysis

Almost every EIDE or SATA hard disk includes S.M.A.R.T. data. That information is collected by the drive itself and contains data that the manufacturer considered relevant to check reliability. The data is made up of several attributes that have a current value, a worst one, a threshold, some raw data, and some flags. Basically, when any attribute's current value is below its threshold, the hard disk is considered unreliable and likely to fail. By using several techniques, this report tries to give a wider range of information, basing its analysis on advanced comparisons with normal values based on real hard disks and on expert-like checks. The final results are not to be taken as an absolute truth, but they are almost as good as a professional expert advice about your hard disk status.

Your hard disk is a ST3500320AS with firmware SD15.
The average temperature for this hard disk model is 31°C (min=24°C max=40°C) and yours is 24°C.

All the attributes of your hard disk are above the S.M.A.R.T. thresholds set by the manufacturer. This is good.

The overall fitness for this drive is 92%.
The overall performance for this drive is 92%.
