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]


The 128GB Samsung 830 is nearly two and a half years old which puts it at a significant disadvantage to more recent models. With peak and average sequential read/write speeds of 512/323 and 410/239 MB/s it's not too shabby, especially considering its age. The sequential figures actually match the current group leaders. The small file 4K peak and average read/write speeds of 22.5/60.3 and 17/40 MB/s are not as impressive and lag the group leaders by 50%. Reduced small file performance weighs on the 128GB 830's effective speed which is 376 MB/s and 20% lower than the average of 453 MB/s for the highest voted group leaders. Finally comparing the 128 and 256GB versions shows that the larger drive has a superior performance profile, which is not uncommon for SSDs but newer models from Samsung don't share this trait. [Feb '14 SSDrivePro]
