If you are considering buying a PC with SATA III support or adding a SATA III (6.0) adapter and installing a SATA III hard drive then you might be interested in my experiences.
Motherboard: ASUS P8P67 ---1155 socket
Chipset: Intel P67
Processor: Intel i7-2600k ---> standard clocking
Memory: 16 GB OCZ 1600 DDR3
SATA ports: 4 SATA III 6.0 Gb/s and 4 SATA II 3.0 Gb/s
Hard drives: Hitachi 7200 RPM 1.5 TB 64 MB cache SATA III (6.0)
SSD: OCZ Vertex 3 120 GB SATA III (6.0)
Operating system: Windows 7 Pro 64 bit
Measuring tool: HD Tune 2.55
Below you will observe four runs of HD Tune. Two runs were with the hard drive and SSD connected to a SATA III (6.0) ports and two runs were connected to SATA II (3.0) ports.
- The SATA II (3.0) interface maxs out with the Vertex 3 SSD and greatly limits the Vertex 3 performance.
- The SATA II (3.0) interface is equal in performance to the SATA III (6.0) interface for the Hitachi hard drive.
- The Hitachi hard drive is one of the fastest hard drives that I have used.
- The OCZ Vertex 3 is the fastest SSD on the market today.
- Hard drives today still have a long way to go to even get close to the maximum SATA II (3.0) interface rating.
- An extremely fast SATA III (6.0) rated SSD is held back on a SATA II interface.
