Drive more efficient compared to my old Velocity Raptor which nevertheless was operating at 10,000 rev / min. No real differences in transfer large files on the computer. The difference is mostly in the Windows opening 7. With a 3 GHz processor, 6 Giga Ram, and a minimum of programs that open at startup, the computer opens Windows 7 in 7 to 8 seconds , against nearly 30 before. A performance! Same thing with the closure of the computer. And I said that my computer will only turn in Sata2. We should therefore be able to improve these ratios. Installation is super easy. The SSD allows again to install or (re) W7 much faster than a mechanical disk even Raptor W mentioned above. However, on my computer, the PNY drive carrier by Amazon sold almost useless. The mounting holes are not located in the right place. Or, you have the tinkering. The PNY media even when positions the flat disk on a desktop PC like mine. A final word on the My Magician software. In Sata2, I found that it was also not really useful. While it improves after optimization speeds, but only on paper at home. That is the theory. In the operation of the disc, that changes nothing. It is already fast standard. Be careful in handling this software! For standard use, I recommend you to activate the "Rapid Mode" that eats lots of Ram memory. About half is a good Giga more to stop doing nothing.
