An excellent value for SSD at less than 300 with a 5 year warranty which is found only on pro equipment! Received 48h (Amazon still as good!), I installed it today. I used easeUStodobackup (see on the site lesnumeriques.com), which I cloned my DD by plugging the SSD on port USB3 with the little box Icy Box purchased together (and received in the same package) in 4h about, without having to do anything: formatting, partition ... but be careful to remove the automatic sleep not to interrupt cloning impromptu and I replaced the original DD DSS and my microphone (DELL XPS) has restarted stride. Speed is at the rendezvous, it became operational in about 35s, when I press the power button to the time my internet access is operational. I had almost 2 minutes earlier. The gain is also very sensitive with Pinnacle Studio 12 that I use for my video editing. The Windows performance test of SD from 5.9 (Hitachi 512 GB to 7200 / min) to 7.6; above that of the processor 7.1 (a I7QM820). Really, a purchase that I do not regret that I advise. I wish to move to a 1TB model, but it's still a little above my means and I just back up my voluminous data (video and photos) on an external hard drive when use this scarce (usually 2 years after taking them, looking at least). A purchase that I recommend to anyone who wants to boost an aging but powerful micro!
