SanDisk Extreme 2 To NVMe SSD - Laggy when accessing storage

My SSD is very laggy when accessing the storage. By accessing I mean when I want to copy paste something, it spends few seconds to operate. Then the operation seems to go to normal speed.
I use the SSD as cache storage for After Effects software, meaning that i have many operations, losing these few seconds everytime.
How can I deal with this issue?

I’ve had troubles with external drives before, and it’s frustrating when I can’t access my files. Fortunately, I was able to retrieve everything with the help of EaseUS Recovery. However, I’m not sure if I want to continue using Sandisk. SanDisk Extreme SSD Failure: Tips to Prevent from Further Damage
