A short story about data retention on modern SSDs and a word of warning about leaving them unpowered. I recently helped a friend move his data to a new machine - and because of kerfuffle by his IT department - his new laptop arrived with a small SSD, so we had to leave some data behind until a larger one was available. I volunteered to move his Windows installation and old data on the new SSD as soon as it arrived, but life got in the way and 6 months went by before he showed up. 🧵 1/4
