Why do I need a SATA III traditional HDD exactly? Isn't SATA 3 mostly because SSDs are faster that 3.0 gbit/s? Why do I need SATA 3 on a traditional spinning hard drive if the hard drive can't read or write that fast anyway?

A 64mb Cache probably doesn't bring much benefit to Sata 3 anyway, indeed SSDs are needed to take advantage of it.

Sata 3 are 6.0 gbit/s, which are faster transfer rate than the older Sata 2 at 3.0 gbit/s and Sata 1 are 1.5 gbit/s. Sata 3 mechanical drives are usually 64mb Cache where as the older Sata 2 drives are 32mb Cache.

SATA 3 on a 5400rpm drive is still kind of stupid. You're only getting the benefit on the cache. And no one is going to use this drive for a boot drive. So why would you need rapid access to small files? It's only SATA 3 for marketing purposes. Namely, it has a 3 instead of a 2. <3
