    Currently looking into the purchase of a new laptop with 256 SSD as soon as Windows 8 releases later this month. How fast does the SSD degrade? Is there a schedule or timeline for the average degrade correlated with use, or some other factors? Are there any laptops that you would not buy, because of the SSD part manufacturing source? Any tips on how to slow down this process?

    It's purely usage that causes SSD degradation. In theory each cell has a limited number of writes.

    That said I have a 40 gb corsair force that I have been using for almost 2 years and even with a few of the supposed no nos such as leaving a page file on it, it is still at 100% health.

    Tbh with modern wear levelling technologies even if you designed an experiment to kill a 256gb SSD it would probably take you weeks if not months of 24/7 usage to do it.

    EDIT: Just to be completely clear by 24/7 usage I mean literally overwriting the entire drive continuously.

    Took me a while to find this blog I read months ago but a guy on the corsair forums actually did such an experiment and it took him over 240 TB of writes to kill a 40 gb drive.

    lots of online guides with settings for SSD's

    key point about an SSD is that access time is constant across the whole disk - so turn off defrag turn off pre-cache , they wont make your drive faster - turn off indexing unless you use it , that sorta thing

    make a 100mb ramdisk and set that as your cache for your web browser, that way you save writes and when you shutdown your cache is completely wiped. and you won't miss the 100mb of ram
