Regular freezes ssd. What could be the problem?

Question

macOS

Hello.
I installed a second hard drive (ssd) in my mac mini 2012.
TRIM enabled, system information shows "TRIM support: yes".
I restored the system from Time Machine so that it was on ssd.
The problem is this - about every half an hour or an hour, the ssd "freezes" for about a minute, and then everything continues to work.
The system continues to function normally at this time, but the disk is not accessed. That is, if I, for example, watched a video, then the picture will stop until the unfortunate minute passes. Programs not using the disk at this point work fine.
On Windows installed via bootcamp, there is no such problem.
Mac mini 2012. OS X Yosemite 10.10.2. SSD - PLEXTOR PX-256M6S.

Answer 1

Disable trim.

Answer 2

Try turning off indexing. It helped me, although of course the method is inconvenient, but I hope it's temporary.
