SSD's has many benefits over conventional hard drives, but when it comes to write endurance it is important to choose the technology to be used with care.

We have noticed a number of returns with failure related to write endurance on SSD devices. Normally, it is possible to "prove" that failures occured by accessing life data from a defective SSD through the S.M.A.R.T interface and protocol indicating too much data has been written to the SSD device.

It is of very high importance to consider several aspects when using an SSD for a particular application, below the most critical ones, such as:

- Nature of the application, data written to disk during a defined time period (worst case).
- OS and applications settings, optimized for SSD.
- SSD selection, there are several choices of price and performance.
- Expected system life, using worst case calculations.
