When we sampled the previous generation 840 EVO from SAMSUNG we were very impressed. It was reasonably priced, had good encryption qualities and in stock format was also a very fast drive. Add RAPID technology and the drive became a performance beast. So, with today's example being a refresh of that SSD we are hoping for much the same, if not more. It would be fair to say that this drive, perhaps more than most is eagerly anticipated by the enthusiast market due to the popularity if the 840 EVO but that isn't to say that the 850 EVO is aimed purely at the enthusiast market segment because with the popularity of Ultra books and the demand for fast data access ever increasing, all users in the PC market will benefit from a drive such as this so when the chips are down - how does this drive perform? Is it value for money? A worthwhile investment or an unneeded rehash?
