Question Computer randomly beeing slower than usual, especially just after boot

[keepuru]

Hi, I have 3 disks in my system, the main one is a Kingston A400 480GB and the other 2 are Western Digital 2TB (yes I know, they're at 5400rpm so they're slow but I put them in raid 0 and it was fine before the beginning of this week).
I tried running some benchmarks and those are the results I got; is this score bad? if not what do I look for to find what's causing the slowing downs?
System:
CPU: Ryzen 5 5600x, GPU: GTX 1070, MOBO: MSI MPG B550 GAMING PLUS ATX, PSU: be quiet! Straight Power 1000W, heatsink: Be Quiet! Dark Rock 4
OS: Windows 10

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition.

Disk drives: how full are the drives?

Run the applicable manufacturer's diagnostic tools on each disk

Before doing anything.

Be sure to back up all important data at least 2x to other locations than the drives in question.

Verify that the backed up data is indeed recoverable and readable.

Hi i updated my specs in the post;
You can see in the pictures how full are the drives, anyway, they're both basically at 40 percent capacity;
I did a backup and tried to use the softwares from kingstone and wd:
the software from kingston couldn't find my drive and the extended test from wd passed without any problems.
