Obviously, the MX100 is a great replacement for the M500, as it proved to offer the same - even a bit higher in some cases - performance, the same features at a lower the price by using smaller lithography NAND.

But the basic advantage of the MX100 is its price/GB. You can buy the 256GB version for $115, and the 512GB at less than $215. Both prices are extremely low for the competition and we should expect to see a response from other SSD makers.

We find it hard to list any negative for the MX100. With the performance and feature set, combined with pricing, the choice is obvious, unless you are an enthusiast or professional with a heavy IO workload.
