It’s a good idea to move of ssd. I also added an ssd after having 2 corrupt sdcards. I just bought a very cheap ssd and adapter to check if that works. So far it’s been running for several months:
Here is my list:
SSD: https://www.aliexpress.com/item/Mini-PCIE-mSATA-SSD-SATA3-iii-SATA-ii-8GB-16GB-32GB-64GB-60GB-128GB-256GB-HD/32711811258.html
SSD-Adapter: https://www.aliexpress.com/item/Super-Speed-Mini-USB-mSATA-SSD-to-USB-3-0-Converter-SSD-Adapter-Card-High-Quality/32820898209.html
And a short usb cable to connect the adapter with the raspberry pi.
