I'm after a 250gb SSD. Both are the same price on Amazon (£70- £72).

Is there any reason I should go for one over the other?

I've checked the benchmarks etc. I see barely any difference. I am more interested in reliability and quality of the cloning software really, if the performance is very similar in both.

Many thanks.

Hmm, I have just put one of each into two brand new HP laptops. The only difference between these two laptops is the screen resolution. And I mean everything. Almost identical amount's of data on both too.

The Crucial MX200 boots 4 seconds faster. I wonder why this is. The Samsung has slightly better benchmarks.

As well, the Samsung 850 is .2mm thinner, which fits better in one of my laptops.

The Acronis cloning software is better and easier to use than the Samsung one in my opinion.

Maybe irrelevant, bu the MX200 feels quite a bit heavier than the 850 Evo.

For some reason I prefer the MX200, because of the problems I read about Evos. 840 has some problems and so has this 850 with a dodgy patch that bust some at the beginning of this year. I feel a bit more confident in the reliability of the MX200, It's just very slightly cheaper too.

Ok yes everyone seems to say the Samsung's. I'm not 100% sure why in all honesty.

But anyway I have decided to keep one of each, and see how I go. As I got a very good deal on both, that I can't change now if I want to keep the deal.

Because it's better than any other and pretty much every review states so. The only way to find that out is by reading them. So here's one:

Well that is for the 850 pro which is 45% more expensive and it does not look like there's a 45% performance increase? It kind of appears to me that in fact you are paying extra partly for the 10 yr warranty.

Yeah sure it has a 10 year guarantee, but most likely the mx200 and 850, 840 and so on, will probably last 10 years anyway for most people.

I'd stick even with the EVO anyways, now its really not like that. The crucial might last 10 years anyways, but the thing is that they are built differently, isnt just a matter of branding. By nature, the samsung is supposed to last much longer. The MX200 is built under a 16nm NAND, now to get more capacity, instead of making components smaller, samsung decided to stack them on top of each other using 40nm process, wich is more convenient for this matter and last much longer. V-NAND as they call is something that others will actually follow, trust me for theres a limit on how small they can be, plus the other downsides of the shrinking process, like lower MTFB as they go smaller,so why not get ahead with the tendency?

I might come too late, but still my two cents:

- Samsung has their new 3D VNAND technology in their 850, but that is still TLC. Crucial MX200 has MLC with SLC cache. In general, MLC is known to have more write/erase cycles (better endurance) than TLC but Samsung's V-NAND TLC is not anymore the old TLC it used to be, so these days we can say that V-NAND TLC is not worse than MLC. Of course, V-NAND MLC is even better (such as Samsung's 850 Pro, if I remember correctly)

- Crucial's firmware seems to be optimized for benchmark-like workloads which are more typical for servers, but not for day-to-day average consumer use.

- Samsung has better software and advanced feature support (encryption, special features etc.)

- bad thing - Samsung has that old bug which makes your drive to slow down with time. My 840 EVO 120GB slowed down from ~500MB/s to ridiculous 50MB/s after using the drive for 6 months. Samsung claims the bug is present only on 840 EVOs and there is a fix (or a workaround) for the issue. However, some users seemingly experience the issue also on new Samsung models. For the time being, Samsung has no final explanations what are the causes and whether they have fixed it for good or not. Also, there was a TRIM bug for Linux drivers, which was really dangerous and could destroy your data.

So, while Samsung seems great and insanely popular, I'd be cautious with it and keep an eye on the performance after a year or so. It's still TLC and Samsung is pushing it to the edge. Maybe a bit too far.
