Good inexpensive drive!

Pros: Easy installation
Outperformed my 970 EVO (in a different build, benchmark test) once momentum cache was enabled.
Crucial Storage Executive can boost the read/write speeds by 7-10x, if you have enough Memory installed and can enable a Momentum Cache.

Why would you pay this much for a SATA M.2 drive when you can get an NVMe drive

Pros: It works.

Cons: For just a little extra, you can get a Samsung drive that will give you 3-5x the performance of this drive.

An excellent laptop SSD

Pros: A good performance, very low-power SATA SSD. Great for laptops and backup drives.

Cons: Slows down more than other drives if it gets completely full.

Other Thoughts: This drive is slightly larger than other drives in its class, allowing more room for storage or overprovisioning.

Less than 525

Pros: -More storage for a cheaper price than my other SSD.
-Fast.
-Easy install.

Cons: - Was shorted 35+ gigabytes.
- Remember to reformat the drive in Windows settings.

Manufacturer Response:
Thank you for your review of the MX300.

The drive you purchased is 525GB in decimal gigabytes. Unix based operating systems like Mac OSx and Linux when formatting this drive will report 525GB. Binary based OSes like Windows on the other hand convert the decimal GB into binary ones, so you end up with a conversion ration. 1KB is 1000 bytes in decimal, in binary 1KB is 1024 bytes, which is why you see a difference. The storage industry as a standard uses decimal measurements when advertising storage space. I hope this clears things up a bit.

So EASY!

Pros: Flawless transition - Very little setup time - Acronis software made it so I did not even need to reload

Cons: TINY bit more cost than other places, but not enough to worry over, and I was buying other stuff so paid for convenience.

Other Thoughts: Was a bit nervous I was going to have to spend all day reloading after deciding to swap out my old Intel 320 series for this guy.
Honestly, could not have been easier. My motherboard gave me more trouble than this - ASRock Fatal1ty shares M.2 with the SATA port my old boot drive was in.
Switched the Intel to a different port, booted up, loaded Acronis, it spent 6 minutes cloning.
Shut down, pulled the Intel, updated boot device priority in bios, and I was live with my old load on my new drive.
So far I could not be more pleased.

Look below

Pros: It works very well. Impressed by the speeds.

Cons: It's currently snowing where I am. I didn't know it was custom to leave packages in customer's yards where there is snow on the ground.
Doesn't come with any instructions at all. It took me hours to figure out that M2 when installed disables one of your SATA ports. I had been trying for hours to figure out why my PC wasn't detecting my main drive with my OS on it after having installed the m2.

Other Thoughts: Overall the product is fine and works exactly as advertised. Just angered with how it was left out in the middle of my front yard in the snow. Talk about laziness. I suggest newegg ship with another service.
