The Crucial MX300 750GB SSD Review: Micron's 3D NAND Arrives
by Billy Tallis on June 14, 2016 9:00 AM ESTAnandTech Storage Bench - Heavy
Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here.
The average data rate of the MX300 is virtually identical to that of its predecessors, except that when full the MX300's identity as a TLC drive is revealed by a precipitous drop.
The average service time of the MX300 when running the test on an empty drive places the MX300 between the slow MLC drives and the fast planar TLC. When the test is run on a full drive the average service time grows to be close to that of some of the cheapest drives on the market.
When run on an empty drive, the write-oriented Heavy test doesn't produce a significant number of latency outliers, but on a full drive delays are quite common.
The MX300's power efficiency is once again very close to the top of the charts, even for the full-drive test.

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.
