SSD as After Effects Disk Cache turning itself off / not working properly
on Jan 23, 2017 at 11:23:06 am

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)

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:
