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 '16 SSDrivePro]
