I just upgraded my old 80GB Intel SSD to a 256GB 840 EVO. I ran the benchmark tool in the Samsung Magician app and get the below results. Is it normal for this app to display such odd results?
It's RAPID mode that shield those results. Disable it and you'll get the real results (should be around 540 MB/s Read and 500 write) Unless you copy a lot of stuff to the SSD, I would recommend you to disable it. In my testings, It normally hurts more than it helps.
