Samsung is the 800-pound gorilla of the solid-state drive (SSD) world. Because of its size and capabilities, the company can manufacture every single critical component inside its M.2 SSDs, including the flash memory, the controller chip, and the firmware. This is a position that no other company enjoys—not even Intel, which is able to produce its own flash memory (known in SSD lingo as "NAND flash"), and its own circuit boards and firmware, but uses third-party controllers. This puts Samsung in a rare and enviable position, and one that it says allows it to fine-tune the performance of its SSDs in a way that other companies simply can't match. Though that sounds like marketing bluster, Samsung actually backs it up with class-leading performance across its SSD lineup. So there does appear to be some evidence of it. Although today's review is about the all-new M.2 version of the Samsung SSD 850 EVO ($119.99 for 250GB), let's rewind a bit and look at the context of this SSD. Si...

The SSD 850 EVO M.2 is the best-rounded SATA M.2 SSD we've tested so far, offering a superb blend of performance, endurance, affordability, and killer software.

Excellent all-around performance; Field-leading SSD utility software; Competitive pricing for M.2 form factor

SATA-bus only; Maximum capacity in SSD 850 EVO M.2 line is only 500GB

I'd owned my computer for 2 years without issues. Then, I installed this and my screen started having issues almost immediately and broke shortly after; so I got it replaced and that screen broke again shortly after; so I got it replaced again and it *also* broke shortly after.

The SSD was received within the stated duration, after installation to a Raid server and performing tests, it proves to be a competitor to modern day SSD that have newer manufacturing processes

The look of the item can trick you to think it is a 2.5" standard physical size. But it needs an adaptor in my application before in my laptop.

I just purchased the Samsung 850 Evo in a z270e Strix motherboard. It was an ease to install once I realized this takes a SATA port away from motherboard. So you will have to move your primary hard drive if its using the first port. This threw me off guard as my primary dive disappeared.

just now added to my HP x360 EnvyM6 AQ105 18h nov2017 its very easy and magician software by Samsung is awesome after so many days of reaserch and hard work finally work is done with a great fear as my laptop was brand new with HDD no ssd now i can use both for booting ssd M.2 sata and HDD as...

Lightweight

Used this to upgrade an HDD laptop which had a spare unused m.2 slot, as always with SSD's the performance upgrade is just out of this planet, once you get one of these in your computing life, you'll never be able to use a computer with a classic HDD, nor should you!

If I had a better budget I would've bought a 500 GB. But it's fine, I dont use that much. easy to install on my Dell i7-6700HQ. came with everything necessary

Even though it has only been a month, I have been pleased. The reputation of Samsung's solid state drives is a€| well, solid, so I feel I can trust it with my data. I added this to a laptop with a platter drive as I wanted the extra speed for video editing when I am on the road.

Easy to install; Great speeds

Windows 8 did not seem to recognize it at first; Formatted through Linux, and then it was fine

This is my first M.2 ssd and I like it. I bought a Startech USB 3.0 adapter in order to clone a 128 GB M.2 ssd to this one. The drive is keyed as "B and M" and you want to make sure that your motherboard accepts it.

Small and lightweight compared to a standard SSD; Very fast; My
