Seeing as larger SSDs are for the most part faster, and I most definitely want to have my OS and games separate, AND I want them both on SSDs....

Would having both OS and game library on a larger partitioned drive slow them down since both partitions would be in use? Or would it still perform faster than having to smaller drives?

For your OS, all you need is a low-cost 64GB SSD. That'll also allow plenty of room for drivers. Use the larger, faster SSD for your games.

Smaller SSDs are usually much slower when it comes to writes, but reads are on par with the larger capacity models. With your OS and drivers on the small one, this won't matter because 99% of the time it'll only be used for reads.

Using a partition on a single drive doesn't help very much on a regular HDD, but it is a little better on SSDs, but not nearly as fast as 2 separate SSDs. The problem with the partition on an SSD is all the data still has to be crammed into the SATA wire, which is usually at capacity even without a partition. When the SSD reads data from each partition at the same...

When the SSD reads data from each partition at the same time, you're instantly bottlenecked by the SATA 3 bandwidth limitation. With 2 separate SSDs, each with their own SATA 3 connection, data flows smoothly and makes for a happy gamer :)
