SSDs have a strange difference when it comes to reliability. Since there are no moving parts, their reliability during their useful life is damn near perfect. However, each memory cell "bit" can only be written to a specific number of times. So, if a SSD is used to write data non-stop, it will eventually start failing spectacularly, because the drive's controller balances the load on all the cells to ensure the longest life. Once any of them start failing, they all start failing at the same time. They also have more physical capacity than available capacity to make up for this issue, so if you write to a 100GB SSD 10,000 times, in reality you only wrote to each memory cell about 8,000 times, or less.
So, in this case... yes, you can use an SSD and get extremely reliable performance for a given period of time, like 2 to 4 years (depending on the amount of writing you do, the drive model, and so on). However, you would want to replace it at the end of the drive's warranty period because you won't see it coming with it starts to fail (unless you don't mind it failing completely out of the blue one day).
