Crucial MX300 SSD Review 750GB

Crucial have been producing high-quality SSDs for some time now but like many other drive manufacturers their products had become small tweaks on existing tech. Today though we get to see something a little bit different with the introduction of an SSD based on their brand new 3D NAND tech. Welcome to our Crucial MX300 SSD Review 750GB.

Crucial MX300 SSD Review 750GB – Packaging and Bundle

Crucial stick with some fairly standard packaging on the MX300, giving us a clear view of the drive design while also giving some product info on the front and back. Inside the drive is encased in plastic and bundled with it is a bumper to help create a better fit in thicker bays and a code to install Acronis True Image HD (to move our data from an old drive to the MX300 quickly and easily). Also available to us, and shown below, is Crucial Storage Executive. This free application allows us to monitor and maintain our drive, including the ability to secure erase it or update the firmware.


Crucial MX300 SSD Review 750GB – The Drive

On the MX300 Crucial go with the same metal casing as other recent models. This is a clamp based chassis with no screws present and to the top and bottom Crucial apply their branding stickers. A SATA 3 (6GB/s) connector sits on the end as does the power input. The drive has a 7mm thickness and is a 2.5″ form factor model (The bundled bumper takes our thickness to 9.5mm if needed).

The MX300 uses 32 layer 3D TLC NAND from Micron with a Marvell 88SS1074 controller and 512mb of LPDDR3 cache. The performance for this model is 530MB/s read and 510MB/s write. The drive also features Dynamic Write Acceleration, a feature which switches some of the NAND (up to 1/3) into SLC mode to enhance performance in some operations. IOPS on this new model are rated at 92k/83k with power use of 75mW when idle and a peak of 5.2W in use.

All of the standard features we would expect from a mainstream SSD are present, such as TRIM, Garbage collection, temperature monitoring/protection, AES 256bit encryption, power loss protection and SMART Support. It has a 3-year warranty (220TBW or 120GB per day equivalent over 5years).  Crucial also add a feature called RAIN which works like RAID, storing data in multiple locations to improve reliability. Finally, this 750GB model has a formatted size of 698GB in Windows.

Testing was performed on an i7-5960X with X99 motherboard, 16GB of DDR4 and on Windows 10. All software, drivers, and the OS were up to date.

Crucial MX300 SSD Review 750GB – Conclusion

With the release of the MX300 Crucial become the second manufacturer to bring an SSD to market with 3D NAND and overall it is a well-rounded product. We always like to see an SSD arrive with metal casing, it makes little difference to the day to day use, but looks and feels nicer while also offering more protection for the internal components should something bizarre happen and cause impact to your SSD.

As far as performance goes, we have no complaints. The raw numbers for peak performance are a little lower than some competitor models however in real world use the drive is very competitive, even edging ahead in some copy tests. It was also good to see the drive maintaining its performance in large read/write operations where some drives drop in performance over time.

The software solution provided by Crucial is also good. The Acronis application allows us to quickly and easily move our data from an old drive to the MX300 and Storage Executive is a responsive, intuitive application which helps us maintain the drive over time. As far as pricing goes, Crucial are listing the 750GB MX300 at $199 which is a decent level for this capacity of drive. Finally, if we were being a little picky we would say that a 5-year warranty would be more appropriate for a drive in this class, rather than 3-years but we can’t complain too much really.

Summary: A well-rounded product which offers good performance on the SATA interface and the latest NAND tech. Decent pricing and a good software bundle ensure that the overall product is good value.
