Hello there! I am Charity, I'm an Independent Advisor. I'm glad to help you today!
Yes, you can move an internal SSD to an external caddy and still boot Windows from it, but there are some things to consider.
You can configure your Lenovo P15s to boot from the external SSD by adjusting the boot order in the BIOS or UEFI. As long as the external SSD is recognized by the system, you should be able to select it as a bootable device when needed. The key is to ensure the boot priority is set correctly in the BIOS.
Windows should boot and run from the external SSD, but performance might vary compared to an internal SSD, especially depending on the connection type (e.g., USB 3.0 vs. Thunderbolt). Some users report slower read/write speeds compared to internal drives, but generally, SSDs are faster than traditional HDDs even in external enclosures.
Also, Windows might have issues with sleep mode or hibernation when run from an external drive, especially if the USB connection is interrupted or if the drive enters power-saving mode. This could cause instability when resuming from sleep.
Please let me know if you have any more questions, I'll do my best to respond as soon as possible.
Kind Regards,
