Does it have SATA 2 or SATA 3? null

Update to previous post: I installed a Samsung 850 EVO 250GB SSD in my system today. The SATA controller is definitely SATA rev. 3 (6Gb/s - 600 MB/s). Benchmarks show 500 - 550 MB/s on both read and write data transfer rates. Performance increase is close to 5 times the stock 5400 RPM SATA rev. 2 drive data rates. See attached images for details.

My unit came with a Toshiba MQ01ABD100 5400 RPM hard disk. This is a SATA rev. 2 (3 Gb/s - 300 MB/s) drive. I'm not sure if the E45T-B4106 model supports SATA rev. 3 transfer rates. Another comment was made that noted a new SSD installed in this system was only reaching 250 MB/s which would lead me to believe that the controller in this system only supports SATA rev. 2 data rates. I have ordered a Samsung 850 EVO 250 GB SSD to put into my system, and will update with my results after installation. Even if the controller only supports SATA rev. 2 data rates, the improvement will still be dramatic over a 5400 RPM spin drive. The original drive as installed only reaches about 100-110 MB/s transfer rate, with average seek times (12 ms.). A Solid State Drive running at 250 MB/s (SATA rev 2 rates) would double the throughput and have far superior seek time (none) and latency (none). Attached images show original hard disk info and benchmarks. SIV identifies the controller as an Intel P9-LP Chipset SATA Controller, running in AHCI mode. Since this in an entry level system, Toshiba may have limited the hard disk controller performance by design.

Thanks for doing SSD performance test on your toshiba E45T-B4106 laptop. Please check user benchmark from my system at http://www.userbenchmark.com/UserRun/210794 It has below explanation on the boot drive: The boot partition is located on a SATA 3.0 SSD but it's only operating at SATA 2.0 speeds. If this system has a SATA 3.0 port then plugging the boot drive into it will improve system performance. While replacing the HDD with SSD on this laptop, I noticed there were 2 strip wires (called Ribbon Cables) which are going above the Harddisk which I had to take out and then keep them after installing SSD. Is not properly replacing these cables might have caused the SATA 3.0 performance drop to SATA 2.0?

This laptop features a SATA III hard drive.
