Note: 1 GB equals 1 billion bytes. Actual useable capacity may vary.
*Based on the published specs of the 525 GB model. Speeds based on internal testing. Actual performance may vary.
**Active average power use comparison based on published specs of the 750 GB Crucial MX300 SSD and the 1 TB Western Digital Caviar Blue WD10EZEX internal hard drive, which, as of January 2016, is one of the industry’s top-selling internal hard drives. All other capacities of the Crucial MX300 SSD have comparable active average power consumption specs, with the exception of the 2050 GB version of the drive, which consumes 0.15 W.
***Validated by testing included in the 'Enhance Burst Performance on Micron and Crucial SSDs Using Momentum Cache' whitepaper.

Top reviews from United Kingdom
There was a problem filtering reviews right now. Please try again later.
Was my first time replacing HDD with SSD, with some reading and research, managed to do it without much problems.
Now the four year old laptop is seriously quick! Of course time will tell how well the drive performs.
If no updates here, means all is good :)
If anyone considering upgrading computer / laptop with SSD, go to Crucial UK website, find the free little software that will scan your computer and advise you which drive to buy. Then buy it from Amazon, you will save £££.
UPDATE... Four months on, laptop is working well. Battery lasts much longer with SSD.
Had a problem with a Crucial M4 until they finally fixed the firmware, this is the same issue (a long power cycle usually brings it back), but then it just randomly disappears again - completely unreliable. I have updated this MX300 525gb with the latest firmware, tried using different SATA ports and different SATA cables - either it hates my build of Windows or my motherboard, or I'm just unlucky as most reviews seem positive.
Loath to return as I got it at a great price on a lightning deal, but completely pointless if I can't rely on it staying available
The laptop is a recent (2017) MSI Apache 17”. It has space for one PCIe SSD and one standard SATA 3. I chose to go with a standard SATA because I’m lazy and didn’t want to mess about with moving the system disk.
Anyway, all good, and decent for a SSD (but not outstanding figures) in CrystalDiskMark. That is until I downloaded Crucial Storage Executive and enabled momentum cache.
The figures speak for themselves (see my screenshot of CrystalDiskMark).
I've also added a second image from Task Manager showing how momentum cache works. The G drive is a traditional HDD transferring 25GB of data to F, a 1TB SSD with momentum enabled (I'm actually installing the game Fallout 4 from G to F). You can see that the SSD only occasionally writes data (about once every 10s).
So, a very good thing about Momentum cache is the way it handles small files; it caches them to memory and only writes them to the physical SSD occasionally. This not only saves wear on your SSD, but it also makes certain tasks fly. I am a web application developer, and my build process (which involves working with literally thousands of javascript files) is now super fast (it would be even faster if node/npm was multi-threaded, but that's another story!).
What are the downsides of doing this?
Momentum cache uses your PC memory as a read/write cache, so you need to have a decent amount of memory. My laptop has 16GB, so all good there. I suspect it will work less well for 4GB systems, or if you are using a power-hungry application (such as Adobe Premiere, which I use). It also increases the CPU overhead.
EDIT: I're realised Windows 10 Task Manager > Memory shows you the RAM cache (its marked as 'memory that has to be saved to disk before it can be used for something else' or words to that effect). I copied over the full install folder of Fallout 4 plus DLCs
(29.6GB) onto a Momemtum enabled drive and the cache varied between 1 and 1.5GB. So the 4GB is never reached; more like >2GB.
Crucial strongly recommend a battery backup if you use momentum cache (i.e. you can lose the cached data on a power fail), so other things equal you should only really enable it on a laptop.
The cache is written to the real SSD on power off, so system shutdown takes longer (by 5-10s, so significant).
But yeah, just look at those figures; well recommended for laptops with memory to spare; your system flies!
Edit: Another good thing about the Crucial I'm finding is that it uses devSleep much more often than other SSDs. Since writing this review (5 months), the up-time for my SSD (according to CrystalDiskInfo) is only 9 hours when the physical up-time has been office hours (8.5 hours a day, 5 days a week). The low up-time saves both power and wear and tear, with no noticeable affect on access time. DevSleep only seems to kick in on laptops (it does not seem to affect my desktop), but is certainly something that will extend your laptop battery life (especially if you have two drives) and the life of the SSDs themselves. Oh, I also suspect the up-time is coming out so low because of Momentum Cache (RAM caching means less access requests to the SSD and more devSleep down-time), so devSleep and Momentum cache probably work together).

Only downside is no cables included in the box. You will need an adaptor / cradle also if installing in a full size bay.
I installed into a desktop. Briefly this is how I went about it
- Unplug PC
- Take the sides off, install drive plugging in a spare power cable and a SATA cable to the motherboard.(neither cable is provided)
- Boot it up as normal
- Go to disk management and format the disk (it showed up in BIOS but not in file explorer)
- Load Crucial's software (Acronis) and clone the disk. This took about 20 mins for circa 400Gb and worked flawlessly.
- Have cup of tea and slice of cake
- Done!
- Well nearly, use the bundled software to wipe your old disk and go back to disk management to reformat your original drive.
- More tea
