SSD aka Solid State Drive...all of the have limited number of writes before they wear out. However, all these can be prevented with proper planning and adjustments to your SSD. An average lifespan of a SSD is around 20 years, depending on how the user uses them.
Although SSD are faster by nature, but the storage space proves to be a potential problem as SSD datas are written in blocks. For example, a 40GB data is being stored in SSD, but eventually the total space used may come up to a whopping 52.1GB. This is because data written in blocks are hard to change. If your OS sees 1 bit being written, SSD will take it as 256kb being written. Hence, resulted in the unnecessary storage space being used.
To overcome this, make sure TRIM is enabled. TRIM will allow a SSD to consider blocks of data that are not in used to be wiped out internally. On the other hand, disabling unnecessary OS features also help save space in ur SSD. Features like paging, hibernation, SuperFetch and Defrag, and temporary files, cache and logs can all be disabled.
To further monitor your SSD, you should also keep an eye on your resources monitor to check. =)
