I am planning to buy an SSD for my laptop, but my budget isn't high enough to afford something like a 1 TB SSD; the most I can get on my budget is 240 GB. So I am planning to go for an SSD, which I will plug into my laptop's HDD port; and I will use my old HDD (1 TB) in my optical drive slot using a caddy (I don't use the ODD).
But then I remembered that my ODD SATA port is 1.5 Gbps or 187.5 megabytes per second (SATA I). I ran a benchmark on my laptop's HDD and it is barely touching 95 R/W speed on SATA III. Would I have any performance loss?
