I understand the difference between SATA-2 and SATA-3, and what L1-3 cache are. But I am trying to choose between two internal harddrives. Both are 1TB capacity, with 7200RPM. The difference between the two option is that one is SATA-2 with 64MB cache, and the other is SATA-3 with 32MB cache.
So what would be "better"/faster between those internal harddrives? I will use the harddrive as a second internal (slave) HDD. Mainly for storing and transferring large files.
