    SSD as After Effects Disk Cache turning itself off / not working properly

    petef22007301

      Hi guys,

       

      We bought an internal SSD hard drive - Samsung 850 EVO PRO (512gb) (by accident)

      And ended up buying a PNY 2.5in Drive Enclosure to use with the Internal SSD with the USB 3.0 port of the imac

       

      This SSD was intended to be used as a Disk Cache for After Effects, but it just stops working after some time when I'm working on After Effects.

       

      I can work from 15min to 1 or 2 hours without any problem, then suddenly AE becomes very slow, and I notice the light on the enclosure turned off (when is writing/reading is blinking blue),

      The drive is still "on" on Finder, but when I click on it it takes 5 to 10 min just trying loading (no folder inside the SSD loads) and the finders stops working.

       

      I've already:

      - Changed the USB port it was connected and still got the same problem

      - Changed the USB cable that connects the enclosure to the iMac - same problem

      - Changed the PNY enclosure to a new one - same problem.

       

      I haven't changed the Hard Drive itself, and I would like to erase all other possibilities before I try that...

      Maybe there's a proper way to set up the SSD for AE?

       

      Before I was using a LACIE normal HD thorough Tunderbolt as Disk Cache and I haven't had any problems.

      (but I can see the speed difference of the SSD when it actually works)

       

      Also I've noticed that this only happens while using After Effects..

      If the SSD is plugged but not being used the PNY enclosure's light turns off and as soon as I click on it on finder the blue light comes back on...

       

      I'm using an iMac 27-inch late 2013 - OS X 10.10.5

      And After Effects 2015.3

       

       

       

      The error actually happen once while it was rendering... that's what showed up in the log:
