Before looking at the benchmarks for this drive it's worth noting that it is nearly three years old, a lifetime in SSD's. The Crucial C300 demonstrated a transfer speed of 309.1 MB/s on the real world speed test. The AS-SSD total scores was comparably poor coming in at 640 points. By today's standards this drive is terrible but it is included in the group test simply as a reference because it was once one of the best solid state drives available. [Apr '13 SSDrivePro]

MORE DETAILS

The Crucial MX100 is the first 16nm SSD to date. Aside from NAND, the MX100 shares the same hardware as its more expensive sibling, the M550. Comparing the MX100 and M550 shows that the two drives have similar read speeds but that the MX100 lags by nearly 50% at writing. The newer 16nm NAND reduces costs and accordingly the MX100 is the cheapest SSD (per GB) to date. In terms of performance the MX100 is a compromise which may or may not be worth making depending on individual circumstances. For typical desktop use including email, office documents and web browsing the MX100 is a great choice but power users should look elsewhere. Comparing the 250GB 840 EVO and 256GB MX100 shows that for a marginal premium, the Evo offers better write speeds. (Note: at 500GB they are more evenly matched) [Jun '14 SSDrivePro]
