Have ..... fast yet because I had read that Crucial adjusts the production of MX100. But this has MLC memory cells u. These are dearer to me than TLC. In addition, Top was in Easter offer from Amazon. Mostly Have read only positive things about this SSD u. I still have 840 EVO, I am disappointed in this degree of this (concerning. D. "Leselangsamkeit the old data" despite FW upd. From last year), let's see what will. Have the OS of d. 840 cloned on the MX, but not. Acronis, which I no longer trust a long time, but that's my business So I would buy again the MX100 at any time.
