Sequential Read Performance
For full details of how we conduct our Iometer tests, please refer to this article.
Sequential read performance hasn't been a strength of Crucial's Marvell based SSDs and the MX200 doesn't change that.
Power efficiency isn't too good either because the performance is low, yet the power draw is quite average.

The scaling graph reveals why: the performance at QD1 and QD2 is simply terrible compared to other drives. Most drives max out the SATA 6Gbps interface at QD2 by providing over 500MB/s, but the MX200 requires QD4 before it reaches its full potential.
Sequential Write Performance
Fortunately sequential write performance is much better. The 250GB does leave a bit to be desired with its SLC cache, but compared to competing drive in the same capacity class it does well.
Power efficiency is also decent.

Again the full SLC cache shows its impact, but now the slowdown starts at QD2 already (sequential writes are faster than random, so the cache is filled quicker). The larger capacities scale well and reach their maximum throughput at QD2.

Can i get some advice from you PRO, should i better go get mSata : Samsung EVO 850 or CRUCIAL MX200 ?petar_b - Sunday, September 4, 2016 - link
I've been using Crucials 960GB and few OCZs since their early appearance. 24/7 for 3-4 years, all drives work well, health 100% according OCZ and Crucial health tools.(Funny that OCZ Limited Eddition 100GB still works surviving decent load being bought in 2010... after reading Anand's review about SF-1500 inside).
The only alternative I considered was SanDisk Extreme, but I like Enterprise features in Crucial: pseudo-SLC, Power Loss Protection, Redundant Array of Independent NAND, 256-bit encryption. The "Adaptive Thermal Protection" (shutting down unused storage components) allows me to use them 24/7... I wish I know if other drives have these features...
I think a life expectancy is up to 320TBW, while Samsung 850 Pro is maxed out at 150TBW, so maybe performance isn't the best, but I would keep on going with Crucial because I never lost a drive.
