There are 2 major concerns using SSD:
1) Make sure your SSD hard drive has a lot of spare space, otherwise your SSD would wear out prematurely. Imagine your SSD is 80% full right from the start, and your computer keeps writing and re-writing data onto this same 20% of empty SSD space, causing premature wear out. Modern SSD can only do about 5,000 re-writes on each "space" before wearing out. I personally ensure that my SSD is at least double my current hard drive's data (Win7+Programs+Data) for this very reason.
2) The newer SSD's coming onto market now not only has TRIM support (under Win7), but also has non-OS specific garbage collection.
~If you're using only Win7, it's better to get a new SSD with ONLY TRIM support, with *NO* non-OS specific garbage collection, because non-OS specific garbage collection causes write amplification that theoretically can cause premature wear on your SSD. Imagine just a small 4k write causes SSD to erase/write an entire block of SSD space due to non-OS specific garbage collection. Dare I suggest that Non-OS specific SSD garbage collection is actually bad for Win7+TRIM, causing one additional layer of unnecessary SSD writes, causing unnecessary wear/tear. Time will tell if SSD write amplification due to non-OS specific garbage collection would take its toll or not.
Non-OS specific SSD garbage collection is good only if you are also multi-booting using Linux or Mac OS.
SSD with Win7+TRIM is good enough.
