The MX100 impressed us with its great value but write speeds could have been better when compared to the competition. Crucial have recently unleashed the new and improved MX200 complete with Dynamic Write Acceleration technology on its smaller drives. Why only the smaller drives you ask? Well, it simply is not required on the larger capacity drives. 500GB and above SSDs do not tend to suffer with write speeds as much as smaller drives so it is certainly a welcome addition for those who are looking for a small boot drive. We have the 1TB version for review today which does not require Dynamic Write Acceleration technology but as with all of our SSDs on test we will look closely at write speeds because read speeds appear to have reached a performance threshold with most SSDs hitting the fabled 550MB/s speed. Write speed is where solid state drives can be distinguished from one another.
