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.

The Mushkin Reactor features the same Silicon Motion SM2246EN controller found on both the Crucial BX100 and the Transcend SSD370. All three drives also feature Micron MLC NAND and consequently they all share a similar (and strong) performance profile. These drives were the last batch (early 2015) of budget drives to utilize MLC rather than TLC NAND and as a result they all have reasonably strong sustained write speeds. The more recent trend for budget drives is to utilize a small SLC write cache coupled with TLC NAND, a combination which results in severe write speed degradation upon cache exhaustion. The Mushkin Reactor doesn’t have this problem and both the 500GB and 1TB Reactors only lag the market leading 850 Evo slightly on performance. At today’s prices the 1TB Reactor offers better value for money than the market leading Samsung 850 Evo (compare them). See the current market leaders here. [May '16SSDrivePro]
