Hi
 

I (think I) understand the challenges of using an SSD in a parity pool and why TRIM is disabled.

 

However, I may want to add a 4TB M.2 in a PCIe adapter, simply to be able to use that M.2 SSD in future set ups, where HDDs may not work for me.

 

the SSD will be used for mostly “resting” data (videos, pictures, music), so limited writes, more reads.

 

my questions:

 

1. does not using TRIM permanently damage the SSD or would any negative impact disappear if I put the M.2 in a System with TRIM?

 

2. How slow would the SSD become without TRIM? Does it become as slow as a magnetic HDD or are we talking about „only“ 50% less speed?

 

thx!

Lack of trim may cause a little more wear, but for the use you describe it should be fine.

That depends a lot on the model and flash type, best to try and see, don't forget that if you have a HDD as parity write speed will be limited by that.
