Are SATA III Mechanical Drives Better Then SATA II?


Solid State Drives
When it comes to normal hard drives, mechanical limitations prevent them from taking full advantage of SATA III speeds providing little to no benefits over SATA II. Only solid state drives can take full advantage from SATA III connections since they contain no moving parts and are not bound by the same mechanical limitations.




Mechanical Hard Drives
When it comes to laptops, you need to check with your manufacturer to see if they accommodate SATA III. As bad as that is there are almost no known 2.5" SATA III hard drives in the market. It's understandable since SATA III provides almost not benefits over SATA II in mechanical hard drives. However, as technology increases and solid state drive become more popular, more laptops are starting to accommodate SATA III connections.




So What Benefits do SATA III Hard Drives Provide Over SATA II?
It's good to note that SATA III mechanical hard drives are not a complete bust. Below I compare an HGST Travelstar 7K1000 2.5" 1TB 7200 RPM SATA III 32MB hard drive and an old Seagate Momentus 2.5" 750GB 7200 RPM SATA II 16MB hard drive. The HGST Travelstar 7K1000 is one of the few 2.5" Sata III hard drives in the market. The benchmarks reveal slightly higher speeds by the SATA III hard drive and a significant increase in burst rate.

HGST is the first company to make 2.5" SATA III hard drives for about the same price of a SATA II. For this reason I would highly recommend this hard drive to any laptop owner looking for a bigger hard drive.
