It depends on how much of Data is gonna be written everyday. SSDs have an absolute write limit beyond which they start failing to accept new data (unlike hard drives, whose mechanical parts may or may not wear out faster with heavier use, see the Google study on disk failure rates. So the more you write to an SSD, the faster it will wear out.
Using an SSD as a scratch disk will tend to subject it to more writes, since files that are written to it are used only briefly and then deleted (unlike an OS disk, whose files are written to the drive and then are re-read many, many times).

It also depends on what quality drive you purchase.  There are several other SSDs out there that have been know to have a write lifespan lasting several hundred TBs, even pushing into several thousand TBs.  The average user, even using as a scratch disk, may not approach this for quite a while.
