    hello,

    will be safe to upgrade to Yosemite from 10.9 when using a DIY fusion drive?
    Have anyone tried this already? or any theory about it?

    I have it running on my home fusion drive (Fusion of 160gb Intel SSD + 1TB spinning drive). I did get a strange error about not having enough space on the logical volume to install it, but I just clicked ok and the install continued.

    I think there is a issue with TRIM, but those reports have always been overblown. I'll just wait for the TRIM enablers to be updated.

    Working fine here on my DIY fusion drive. Just make sure you're using one of the updated trim enablers (I use Trim Enabler by Cindori and it works fantastic.)

    Semi-related, I updated to Yosemite on an un-Fusioned drive and it went fine. I just had to choose my drive when upgrading. I like choosing what goes on SSD and what doesn't. Having it automatic made me nervous so I got rid of it. :)
