Performance disadvantage to storing PHP files on HDD?

    I just got a shiny new dedicated server, which has two SSD and HDD RAID1 arrays. Obviously, I plan on using the SSD to host the OS and DBs, and then stick all my forum attachments onto the big HDDs.

    However, I noticed that when configuring the server, the tech has already mounted the entire /home directory onto the HDDs. At first I was going to change it, because I'd like all my PHP files which will be stored in /home to be kept on the SSD for performance, but then I got to thinking: does it really matter? With Zend Opcache and Linux's file caching files in memory, will there be any noticeable difference in performance?

    Keeping everything on /home would make it slightly easier for me to maintain, as I wouldn't have to create application-specific symlinks to store things like XenForo attachments on the HDDs.

    There is a difference still. So worth changing and if you don't want symlinks and only have one forum/site attachments, you can just mount the HDD raid 1 array with a name like /home/nginx/domains/ or something and use addon like [bd] Attachment Store | XenForo Community to move attachments to data directory HDD raid 1 array mount. Haven't tried this mount for data only but that's one thought I'd have. But this forum here uses bd Attachment Store though :)
