Firefox (and likely other web browsers) tends to write data to fixed storage very frequently. When certain browser extensions are installed, the write operations can occur every few seconds.
Because of this, when using platter-based hard drives (HDD), I typically put the needed Firefox profile(s) onto a RAM disk (and then just use a script to automatically write them to non-volatile storage before the computer powers down).
I do this primarily for performance reasons, and also to reduce disk thrashing and power consumption.
With an SSD (as opposed to a HDD), is it fine to just keep the Firefox profiles on the SSD instead of using a RAM disk? Or will the very frequent writes (which can be as many as 30,000 write operations per day) wear out an SSD in less than a decade?
At this time, I only have accurate data as to the number of write operations per day, but not the quantity of data being written. That said, the largest file in a Firefox profile is typically 25MB. So that's the worst case scenario.
The OS is Windows 7.
BTW, the SSD most commonly used at this particular installation is the SK hynix Gold S31 1TB SATA Gen3 2.5 inch internal SSD. The marketing data for those drives claims "MTBF reaching 1.5 million hours, up to 600 TBW".
