The Crucial MX300 750GB SSD Review: Micron's 3D NAND Arrives
by Billy Tallis on June 14, 2016 9:00 AM ESTAnandTech Storage Bench - Light
Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here.
The MX300 establishes a small but clear lead in average data rate over the MX200 when the test is run on an empty drive, but for a full drive the performance again drops down to the level of budget planar TLC drives.
As with the Heavy test, the MX300 has an average service time on the Light test that puts it below the MLC drives but ahead of most TLC drives except when full.
The frequency of latency outliers shows the same split personality: keep plenty of spare area around and the MX300 performs like a (low-end) MLC drive, but fill it up and it will begin to struggle.
For power efficiency the MX300 is once again second only to the Crucial BX100, and substantially better than any other TLC.

Does anyone know the cell size of Micron's 3D TLC?Jimster480 - Tuesday, July 5, 2016 - link
Haha the performance is horrible for the price.Seriously MX200 kills it which means Transcend SSD370s kill it too.
Even the crappy X400 kills it.... where is the Ultra II on the list? I'm sure it kills it also.
3D nand sucks.

These comments show that people don't understand the durability of this drive. Since it's using the 3D-Nand technology that Samsung first adopted, this drive has a better durability rating than a Samsung 850 Pro. Like holy shit.. It uses TLC memory too! It's a TLC drive that's more durable than a MLC drive. It's also a very good priced drive. from $0.26 to $0.24.. That's amazing pricing lol. I don't fucking know why people are complaining.ZapNZs - Monday, September 12, 2016 - link
3D-NAND for the lulz'ers?...I can coat a turd with 24k gold, but at the end of the day it's still crap. And this sure is crap...shame on you Crucial! Given this is [by design] an inferior product to the MX-200, they should have named it something other than the MX-300. TLC has inferior endurance, inferior real-world write performance, and inferior error correction capability. So here we have another TLC drive that is priced almost as high as Transcend's 370, but the 370 uses MLC...MADE FROM MICON'S OWN PREMIUM NAND SUPPLY. Don't count on this drive to give anywhere near the reliability or longevity of the venerable MX-200. This is like changing movie night up from The Godfather to Freddy Got Fingered. Yay Micron!TimAhKin - Friday, November 25, 2016 - link
Got this just now for £100. I think that for this price it's a really good deal.
