Hi!

No, the disk already distributes the stress automatically. But knowing which areas of the disk are currently unused helps to do that more efficiently. So it is good but really optional if operating system drivers or tools help SSD users by providing TRIM data. > How can I tell if TRIM is present. Is there a file called trim.exe. No there is not. Please read the article first: https://en.wikipedia.org/wiki/TRIM As you can see, TRIM is something reported by the SSD as being supported or not. And the filesystem driver may or may not provide TRIM data, while tools such as hdparm or mdtrim help you to manually provide such data. You also see that some drives even have bugs in their TRIM support which makes Linux AVOID sending them TRIM data :-p You can read the data sheet of your SSD or use tools such as Linux hdparm to find out whether your SSD can make use of TRIM information if it is available. In that case, you can try to use Windows or Linux tools for FAT filesystems from time to time to update the TRIM info, or you could work towards making special defrag, chkdsk or dosfsck tool versions for DOS and add extensions for creation of TRIM. Again, it does NOT create any real problem for you to use SSD which support TRIM in DOS which does not support TRIM. You might have a few percent speed loss of your SSD might age a few percent faster, but that is all. You already have huge speed losses by using DOS at all because you probably have a multi core 64 bit processor, huge RAM and your SSD probably supports protocol extensions for multithreaded I/O, none of which is supported by DOS anyway - it ignores those. So given all the hardware power which you are knowingly not using because you limit yourself to DOS, you really should not worry about that little bit of TRIM tuning.
