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]

The 860 Pro is Samsung’s latest consumer-grade SATA SSD flagship, superseding the popular, but now three years old, 850 Pro. Like the 850 Pro, the 860 Pro is based on Samsung’s proprietary and revolutionary (at the time), MLC V-NAND (3D). A 10% price premium over the 256 GB 850 Pro will purchase the 256 GB 860 Pro which has an impressive 16% faster effective speed. This is achieved via an updated controller (MJX) and 64 layers of V-NAND (versus 32 layers per the 850 Pro). The 860 Pro has sequential speeds of up to 540 MB/s which almost completely saturate its SATA 3.0 interface. These peak levels of performance are slightly higher, but still comparable to the peak performance of the 860 Evo before its SLC write cache (12 GB on the 250 GB Evo) is saturated, making the 860 Evo (at around 30% cheaper) a more economical choice for users who rarely write more than 12 GB at a time. There are also reliability improvements compared to the 850 generation with Samsung now offering a warranty of 300 TBW (terabytes written) for the 256 GB 860 Pro, compared to 150 TBW for the 256 GB 850 Pro. Thanks to higher density NAND, the 860 Pro is also available in a 4 TB variant, whereas previously 2 TB was the largest capacity for a Samsung SATA MLC SSD.  [Feb '18 SSDrivePro]
