Do NOT use SSD for any media or files you want to keep
Why though? value your view as well others on all things technical.
Personally I dont trust any hard drives, for various reasons.
I dump them on a HD, copy them to SSD to work/sort with and then copy back to a backup drive.
Flash, by the very nature of its design, is forgetful...........and bits will begin to flip from the second data is written.
To get around this, the suppliers fit controllers to interface to the flash (there is never direct access to the flash chips) which adds extra functionality to reduce this impact. This includes error correction and wear levelling (as flash also get worse every time you write to it), it also splits the part in blocks, you never write to bytes, so you might only update a 32bit line, but a whole block gets read and written......and every time you write you write to two blocks......one being the data and the other the FAT.
But, what happens is that over time more and more bits flip, and there reaches a point where the error correction falls over and a block is lost.......game over for that file.......and the whole partition if its the FAT table.
So the way I drive the use of flash in products is based on a few rules:
1) Work on the basis you never write to it, if you do, limit it to once a minute (the typical life is 800k writes per block....very easy to hit this if not careful)
2) If you need to write to it regularly then use a separate replaceable part
3) Ensure you have AT LEAST 25% spare capacity at all times to allow for better wear levelling
4) If you can, find a part that supports static wear levelling (Silicon Systems had the Pats on this, they got gobbled by Western Digital)
