Server keeps crashing

I have a laptop (a bit older) with StartOS. I got a 2TB disk (internal SSD) and running the server no problem. However, 3 weeks ago, I noticed the laptop keeps on crashing after a couple of days or running. Today I was able to see the screen before it got unresponsive without displaying anything and saw these messages:

I/O error, dev sda, sector XXXXX
BTRFS error (device sda3): bdev…

I’m new to this, what I can gather is something on the disk, but not sure what or why, since the SSD is brand new.

The error seems to suggest you got a bad SSD.

Setting up SSH on your server and running

sudo dmesg | grep sda

and

sudo dmesg | grep sdb

should reveal clues that might tell you some more.
