Ok, it's late. Level with me here. I recently installed a Samsung 470 SSD (256gb) into my laptop (17" 2011). I wonder if the following is possible: 1. Buy another identical SSD, install it in the optical bay (to replace my stock 750gb HDD) 2. Partition both drives in half (128gb/128gb in my case, so four 128gb partitions in total) 3. Create one RAID 1 array/mirror with two of the 128gb partitions (one on each disc) 4. Create one RAID 0 array/striped with the other two 128gb partitions thus creating a mirrored 128gb array for the OS and applications and another 256gb array for storage and whatnot? Just thinking aloud.
