SSD Fragmentation???

Been doing some reading online about SSD's and, since I've just ordered a 160GB Intel X25-M SSD, have a couple of questions about their use. I deduced so far that fragmentation as it applies to HDD's is not a concern with SSD's. The problem with SDD's is a bit different. Following is a quote from this website
SSDs start out really fast and then quickly start to lose their speed and over time become subject to corruption.

SSDs require that old data be erased before new data is written over it, rather than just writing over the old information like with hard drives. This doubles the wear and tear and can cause major issues.

The principle issue is write speed degradation due to free space fragmentation. Small free spaces scattered across the SSD cause the file system to write a file in fragmented pieces to those small available free spaces. By doing so, it degrades write performance by as much as 80% to the solid state drive.

SSDs can only write so many times to the drive as they have a finite number of writes that they can perform. Due to the doubling effect of needing to read and erase before it can write again, SSDs undergo twice as much use.

As the SSD approaches its limit, more fragmentation and write errors occur, causing SSD slows. Write performance decreases proportionately as free space fragmentation increases. All SSDs will suffer from this problem at one point or another unless HyperFast is used to optimize the solid state drive.
Other information suggests one use a feature called TRIM with SSD's which, at least on first blush, does essentially the same thing as Diskeeper 12 Pro, just a slightly different way.

Would just like to know if anyone has had any experience with either TRIM and/or Diskeeper 12 Pro (on Win 8, if possible) and their opinions regarding the value using one or the other with an SSD.

Just my opinion however I would not install a third party defrag app with a ssd. Occasionally log OFF and let the system sit for an hour or two. TRIM works when the system is not doing anything ie logged off. If you still have problems with performance, then do the following;
1 Make an image backup of your system using acronis true image. Store this on a second drive, external, NAS, etc
2 Boot with parted magic linux and secure erase the ssd [do be careful to select ONLY the ssd]
3 Boot with your acronis boot disk and restore the image.

Done and your ssd is refreshed or in the same condition as new.

To add, all you need is TRIM support by the operating system and internal GC that's supported by the drive, that's all you need to keep it operating well. You do not need any useless third party junk ware to keep the SSD working well. This consolidation of files or free space just adds more reads and write to the SSD increasing the wear on the drive and wear leveling algorithms move data around on the SSD as needed, internally and regardless of third party software doing its 'supposed' thing. Sadly this is a last ditch attempt by obsolete companies trying to stay alive where defraging even mechanical drives has little value and none on an SSD.
