The MX300 is essentially a TLC version of the MX200, but with 3D NAND. This opens up higher capacities. TLC Is generally not as durable as MLC, so one might consider that a 'downgrade,' but under normal write conditions it will still last long enough for pretty much anyone. Also, it's enough cheaper that I'd say this one is worth it. Let's face it- most of us aren't going to be keeping the same drive for 20 years... probably not even 10. In fact, I don't think I've ever used the same drive for more than 5 years on a machine I actually use on a daily basis. If you're like me, and you tend to use a machine daily for 2-4 years, then relegate it to a secondary role and only use it once a month... this drive will probably last longer than you will. Ditto if you're basically going to write a couple of programs to it and then rarely ever either remove or change any of it. In my case, I got this to hold a bunch of games and videos I've recorded. Once or twice a month, I might move some of these off to make space, but that's about it. At that rate, this drive will probably outlive me. It's been about a year so far and not a prob yet. If for some reason you're planning on using the same machine daily for 10+ years, or you are fond of doing something that requires a massive amount of data transfer/rewrite, you may want to get something more expensive with MLC flash (e.g. the MX200 or Samsung Pro series). If you're looking at that kind of long-term/long-wear use, then that would be a worthwhile investment. Regarding the interface, yes- NVMe is out now if your machine supports it. Yes, it is faster, but in most cases the difference is going to be pretty small. As far as SATA SSDs go, this one is about as fast as they come. So unless you're willing to pay a really hefty premium to step up to NVMe, you're just fine with the MX300.Read full review

I removed my optical drive and replaced it with the old HDD. Then installed this SSD as my boot and main HD. Installation was easy and everything seems to be running smooth. Now I just need another one to replace my old HDD and try to set up a RAID 0. The reason why I did not give 5 stars is because in the box there is a link to install Crucial's Storage Executive software. While the actual SSD is compatible with Mac, the Storage Executive software isn't. It isn't necessary for the drive to function properly, but does have some convenient features that would be nice to have available. Other than that, I am very pleased and will be buying another soon.

I bought one of these on Feb 01, 2017 to replace the stock drive in my workstation laptop to speed it up & cut down on heat from the stock drive. I had owned SSD drives in the past but when I got this it was about the same weight as paper so I thought I had gotten scammed lol till I installed it & everything worked perfectly. This has been one of the best items I have bought online in years & still performing perfectly. I would recommend the drive model to anyone interested or in need. Now days if you shop around you can get 240GB SSDs for around $40 brand new so there is not as much need for the larger drives other then for gaming. These drives also make an older socket 1366 dual xeon much faster in boot times which is awesome. If you need an SSD drive around this size, this is a great buy!Read full review

Makes your laptop computer run much faster.......definitely an upgrade that makes a tremendous difference.... works wonders.....but the crucial cloning software's complicated......tried it several times but encounter problems......no worries, go to youtube and look for an easier fix......what I did was: 1. downloaded a secure windows app in my 8gb flash drive;and, 2. after installing crucial X300 525gb HD, let your computer boot from your flashdrive and follow, follow, follow......good luck

The speed difference is remarkable. Sips electricity so improves battery life. Lighter, so reduces weight, quiet therefore reduces noise. The list of benefits is impressive. I got the 525gb drive with discount and what a great deal. Crucial even provides a free copy and of Acronis True Image software. I had the new drive cloned and installed in about 30-40 minutes. A+
