I have a Lenovo X200 Tablet with a 128-gigabyte SSD. So far, it's wonderfully fast and long on battery life, so "yay."
How do I keep it this way, though? I usually use System Mechanic, but its support doesn't say a thing about "SSD," "Solid state disk" or "solid state drive." That doesn't make me sanguine, so my question is:
Is there such a thing as disk defragmentation with an SSD? If so, what do I do about it? It strikes me that tools meant for magnetic media could wreak all kinds of havoc.

If you ask me, I would say disk defragment help boost performance especially when reading and writing large files-- and what Lenovo recommends is defragging by its tool--you may read @inside the box, Lenovo's blog for some interesting aspect.
I don't think tool matters. They all do the same basically, but you should not defrag that often. However, If it comes with like 3-year warranty, you don't have to care about that =) just backup often. If it breaks one day, just ask for replacement!

An SSD does not store data the same way a rotating disk does. Since all flash memory chips have a finite number of erase cycles before they stop working the Flash File System automatically spreads data out among the flash chips for wear leveling. The actual physical location where your data is stored is not the same as the logical address the system reports back to you. So I doubt defragging would help performance much, if at all, on an SSD, and it will actually use up some of your limited erase cycles.
I could be wrong but I don't think you want to defrag an SSD.

"Defragging" is not an effective solution.
Most likely you won't need to do any maintenance as the Samsung controllers have not been plagued by the stuttering of the JMicron controllers or the "internal fragmentation" of the Intel controllers.
However, if you do feel that your SSD has become sluggish, I would recommend the following process:
This process is the same method that PC-Perspective used to fix long term problems with the Intel x-25M.
Note, I am not recommend that anyone do this as regular maintenance. However, if you believe that performance of your SSD has degraded, this is almost certainly the fastest and most effective way to fix it.

You should not defrag SSDs like you defrag conventional drives, but free space consolidation at the file system level is said to help to restore random write performance after a period of usage. Since file system fragmentation does not increase read times or sequential write times, only the random write problem needs to be addressed.
