Best use for a small ssd

[brilldoctor]

Ive got a 128gb corsair force ls (warranty replacement for an old force 3) in my desktop (mainly used for computer science degree) however I'm running out of space and was considering replacing the drive (there is a 1tb hdd for data in the pc as well at the moment) which got me wondering what would be the best use for the old drive? Could I somehow link them in a RAID or something?

for raid you need the identical drive and same space for raid 0 also on the small ssd I recommend putting your os on it that's the most popular use and also put programs you use a lot that take long to load up and also games if you game. good luck =)

Thanks - Ive got my OS on the SSD and files on a HDD - seeing the prices of 512 GB SSDs I might wait for them to fall a bit lower
