Kingston are here 450MB / s write speed, unfortunately, the actual reach is approximately 170 MB / s that is be noticeably less than half of angegbenen value.
dit: Who buys cheap, buys twice, I have now decided on a Samsung 840 120GB EVO and am super happy right away, the Samsung SSD achieved in some cases significantly higher values than indicated and that in all benchmarks.
Had the SSD in a UX32VD ASUS Ultrabook to a SATA III data connection (6Gb / s) installed.
