I am on a budget gaming system and the best SSD I can afford (a crucial m500) is 240 gigs. I don't think this'll suit me very well. I can get a Seagate 1TB Desktop SSHD SATA Hybrid Hard Drive 6GB/s 64MB with 8gb SSD chache cheaper (plus much more space). So I was wondering if the difference in speed between the two disc types mattered much
