In Reply to: RE: Some more SSD optimizations, probably you're doing them... posted by Tony Lauck on April 04, 2014 at 12:31:45
Tony, the big concern with wearing SSDs has more to do with large numbers of continuous large writes on a daily basis, not so much the typical and relatively small log files used by most OS's. Even with a good amount of typical daily writes, log files and user data, modern SSD's are expected to last at least 5 years or more.
This is not the case for less reliable cheaply made SD cards, USB thumb drives, etc. These can be plain flaky and unreliable.
One of the reasons you don't defragment SSDs, as one bright inmate here recommended doing, is the excessive amount of writes that it would require with little to zero benefit. There is no real benefit in defragmenting an SSD because it's not like the data is laid down on physical rotating media where having contiguous sequential blocks will benefit performance. The data is scattered over various NAND cells as the SSD controller sees fit.

It wouldn't surprise me if XP didn't create more problems with SSDs than newer OS as the OS hasn't had the TRIM command added. Also, there is the question of whether or not lazy writing has been enabled.

This is why I have dual boot. On XP I run programs that W8 won't plus reliable and easier/more informative Acronis and Diskeeper. On W8 Trim works. On some earlier SSD, you can also run Garbage collect.
I just don't have ANY problems with XP on SSDs. Even w/o dual boot on XP, you can Trim as an external drive or run Diskeeper SSD Free Space Optimizer.
