The fact that they had 2 different system requirements for different features of the OS kind of makes me think that is true. Also surprised to know Vista didn't have TRIM support, but it was also released before or incredibly early in the SSD era, so it makes sense.

Without trim, the SSD will remember every filesystem block that has been used as being valid, so it can reach a not full but full situation where recovering blocks to use becomes slow and causes write amplification. Unused space in the partition does help, but if the system spends a long time in NOT reusing deleted filesystem blocks, more blocks can end up as SSD used / filesystem unused. Unpartitioned space means a guaranteed filter area of blocks that can never be filesystem used. Yes, you can PROBABLY survive ok regardless, if the drive never touches the last 20% IN the partition
Thanks for the info! I'll make sure to keep it in mind if and when I swap out the XP HDD for an SSD.
