The 250GB Samsung 850 Evo has a similar architecture to its hugely successful predecessor, the 840 Evo. Both drives are TLC based but the 850 uses 3D V-NAND as opposed to regular NAND. Both drives also feature a Turbowrite cache (TWC) which buffers up to 3GB of writes. The TWC enables high burst write speeds but when the cache exhausts write speeds drop to 300 MB/s. Comparing the 850 and 840 Evos shows that effective speed, has improved by 11% and the warranty has been extended from three to five years but prices are also up by 11%. The 850 Evo does put in superb benchmarks (second only to the 850 Pro) but these are only valid within the TWC. At current price levels the 850 Evo struggles to compete with the value leaders[Dec '14 SSDrivePro]

The 240GB OCZ ARC has a solid performance profile with particularly strong 4K speeds. The ARC is positioned below both OCZ's enthusiast Vector 150 and the mainstream Vertex 460 but based on hardware specs there is very little separating the drives (newer NAND on the ARC). Comparing the Vertex 460 and ARC shows that the ARC lags particularly in terms of sequential write speed but the overall difference in effective speed is marginal. The broad performance equivalence coupled with the fact that the Vertex 460 is available at the same price point makes the 240GB ARC somewhat redundant for the time being. Given that the ARC is relatively new, prices are likely to drop significantly over the coming months at which point the ARC may make more sense. [Sep '14 SSDrivePro]
