Price: ~$179 at time of publication



Today we’ve got the Crucial MX300 750GB SSD on the old BCCHardware test bench. The MX300 series of SSD drives from Crucial are their top-tier drives and offer more performance than the previous MX200 series of drives.

The MX300 750GB drive is a “limited edition” drive thanks to the unusual size. Typically SSD drives coming in the 512GB capacity and then you double up to a 1TB offering without any options in between. The biggest reason you’d probably choose a drive with 750GB of space is most likely based on budget, typically in a build the hard drive is of the last components chosen and the size typically depends on how much money is left in your pocket.  At time of publishing the MX300 series will run you roughly $129 for a 525GB version, $219 for this 750GB version, and $259 for a 1TB version. Based on the day you go to buy this drive the price will of course fluctuate between the models, and most likely that will help you make your decision on which size works best for you.


The rated specifications provided by Crucial show the Read and Write speeds and IOPS for the 525GB, 750GB, and 1TB, drives in the MX300 series are all rated at the same speeds so moving up and down between the drives will really offer no more or less performance, the choice between the drives should be solely based on what your storage capacity needs are. In the testing section we’ll throw these drives up against a couple older Crucial drives as well as a couple drives from other SSD makers and see how the numbers stack up.

The MX300 series of drives all use the Marvell 88SS1074 controller with a few firmware tweaks from Crucial. The Marvell 88SS1074 chipset is a popular choice amongst higher end drives and there are other SSD makers that use this chipset as well, Crucial however uses their own firmware to try to pump a little extra out of this chipset.
