The hard disk is used by me in a Macbook White mid 2010. In Mac OS X Lion is a clear performance boost can be determined. It should be mentioned that the Macbook, the speed of the hard drive can not quite make fullest. Nevertheless, the purchase is worthwhile: The unit now moves up not only in less than 20 seconds, but programs are also quasi opened immediately. Who frequently unpacked large files, will also experience a significant time savings. In addition, the credit risk is reduced, since no moving parts are more fitted. Incidentally, it is quite used to, that the well-known hard disk noise due to unexpected loss. Corsair makes its reputation as a high quality memory products with this product all the glory. In addition to a wealth of accessories, the SSD offers a solid finish.
