Almost two years old, the Samsung 830 is one of the oldest SSD's in the group test. The 830 has a reasonably consistent performance profile scoring slightly above average (446 MB/s) for real world use and slightly below average for server use. In all probability the 830 is nearing its end of life and as a result is retailing for approx £50 more than it was just a few months ago. Owners of this drive should feel no pressure to upgrade as the real world performance gains will not be significant but people looking to make a new purchase should steer clear as at its current price of £180 there are far better deals to be had elsewhere. [Apr '13 SSDrivePro]
