SSD of the Week – Samsung 850 EVO

In our previous SSD of the Week we looked at the Samsung portable SSD T1, a small and secure SSD for when you are on the go. This week we look at another one of Samsung’s products, the Samsung 850 EVO. We reviewed this SSD back in December and now it has had a very competitive drop in price to challenge some of the recently released SSDs. Also, it even beats the price points of many lower tiered SSDs, while providing better performance.

Samsung 850 EVO-6

The Samsung 850 EVO comes in the 120GB ($77.99), 250GB ($114.99), 500GB ($179.99), and 1TB (399.99) capacities. The 500GB capacity especially is a super value buy now for its price point.  The 850 EVO uses a dual-core MGX controller for the 120GB, 250GB, and 500GB capacities and a 3-core MEX controller for their 1TB. Using Samsung’s 32-layer TLC 3D V-NAND, the 850 EVO can reach sequential speeds of up to 540MB/s read and 520MB/s write across all capacities. Read IOPS for 4KB, QD1 performance is rated at 10,000 and write is rated for 40,000 IOPS.  4K queue depth 32 performance is rated for up to 98,000 IOPS read and 90,000 IOPS write. To achieve such numbers The 850 EVO uses Samsung’s TurboWrite technology which takes a small portion of the TLC 3D V-NAND and simulate it as SLC NAND to achieve faster performance.

Samsung 850 EVO-8

The 850 EVO has quite a lot of features including AES 256-bit Full Disk Encryption which is Windows eDrive compatible. To view the full list as well as see the changes of RAPID Mode from the 850 Pro to the 850 EVO look at the Samsung 850 EVO 120GB/500GB and 1TB reviews, where they won our Gold Seal and Editor’s Choice awards.

The Samsung 850 EVO is a great quality mainstream SSD that was released a few months ago and now it even has competitive prices with entry-level SSDs, what more can you ask for? If you need an SSD now is the time.

The TLC slow down bug. http://www.thessdreview.com/daily-news/latest-buzz/840-evo-performance-degradation-problems-persist-users-now-petitioning-samsung-replace-affected-ssds/

Based on my usage with the newer 3D V-NAND powered 850 EVO, it does not share the same issue.

oh come on, you are overdoing it the usual american way. Never again Samsung. Never again HP because one notebook broke down on me 7 years ago. Never again Dell because their monitor went bust. What you will buy in three years when everything will be “never again” in your book ? Man up ! If you have your SSDs working in temperature controlled environment (=not overheating), you will never get this slow-down problem. I say it’s just improper usage that causes pain. And of course, TLC never was and never will be premium class. I never had Samsung SSD,… Read more »

Thats not true at all. You will get slowdowns regardless of temparature.

You are right, I’ve overdone it a litlle. My apologies. Well some things get me started quite easily. http://www.pcper.com/reviews/Editorial/Samsung-840-840-EVO-susceptible-flash-read-speed-degradation-over-time temperature still plays a role, page 3. Big role. Maybe the TLC problem was corrected or didn’t exist at all, I don’t know – I’m not NAND engineer/SSD architect – maybe it’s all just about thermal throttling of controller. Well it easily might seem that way after the first firmware update, given the “temperature/performance” graph on last page. See, if we like it or not, such semi-fatal or fatal issues are, unfortunately, part of our IT life. And will be more… Read more »

jeeeeeeeez even horses have their own issues : you just can’t run it full throttle, then suddenly stop and shut down.

Even a horse requires “proper handling” 🙂

If its designed propery, thermal issues are the last thing to be worried about.

The reason controller throttles and drops the speeds is becuase it has to do much much more ECC work than usual (because of the errors in TLC nand). That means more heat and thus throttling which in turn further decreases speed.

But heat on its own is NOT the main cause of the slowdowns. Its the small litography nand combined with tlc that makes this soo apperent.
So yeah, this is MOST DEFENETLY a nand issue.
