I believe Magicloud's point was actually due to the limited number of writes available on an SSD. Cons: A swap partition doesn't support TRIM, so deleted pages will be deleted (written) immediately. However, I suspect swap doesn't actually delete data very often (just marks it as unneeded). Pros: Swap is mostly read, rather than written, so an SSD should benefit Alternative: Try a swap file on an ext4 partition. That will allow you to make use of the TRIM function via the ext4.
