How do you think an SSD (like Intel or another version with high read/write speeds) would function with FileVault?

Will the constant reading/writing from encryption/decryption significantly affect the life of an SSD? What about performance after multiple writes for each sector?

It will work just fine.

Will the constant reading/writing from encryption/decryption significantly affect the life of an SSD?

No. At least it won't on any modern SSD with a half-decent wear-leveling algorithm.

What about performance after multiple writes for each sector?

There's nothing special about FileVault that would cause any problems here. If the drive has a decent wear-leveling algorithm you'll be fine. Any drive with a low write amplification rate will do just great -- I've used FDE on Intel's SSDs for a couple months now with absolutely no ill effects whatsoever.
