Samsung 860 EVO V-NAND SSD offers huge endurance improvements

The Samsung 860 EVO offers increased performance and a dramatic increase in endurance over its predecessor.


Samsung dramatically has upped its SSD game by offering the two things that buyers are looking for -- performance and increased reliability.

It's pretty hard to make storage exciting any more, but Samsung's managed that with its new 860 EVO V-NAND line of SSDs.

The 860 EVO builds on the success of the 850 EVO, the world's first consumer SSDs to make use of V-NAND 3-bit MLC technology, and the update brings with it 64-cell layer V-NAND and an all-new MJX controller.

One of the reasons why it's hard to get excited about SSDs, especially when it comes to performance, is that manufacturers have pretty much saturated the bandwidth offered by the SATA 3.0 standard of 600 MB/s (remember, the SATA 3.0 standard is a decade old). Despite this, Samsung has worked hard to remove the data speed bumps that were found in the 850 EVO to deliver a product that is faster -- albeit only a little bit faster.


Samsung 860 EVO performance

Samsung has also worked to improve performance under sustained workloads, with the 860 EVO offering something in the region of a 50 percent boost performance under sustained write loads.


Samsung 860 EVO write saturation performance

Another way that Samsung has been able to squeeze out more performance from the 860 EVO is by using Intelligent TurboWrite. TurboWrite was a feature that Samsung first introduced with the 840 EVO, and it boosted performance by creating a high-performance SLC write buffer in the SSD.

Intelligent TurboWrite, which debuted on the 960 EVO, took this further and allowed the drive to intelligently define an SLC buffer based on the data workload the drive was experiencing.

If we take a 250GB drive as an example, if the user data that needed writing to the drive was under 3GB, intelligent TurboWrite used the default TurboWrite buffer region on the drive, similar to that of the previous 850 EVO. However, if the user wanted to write more than 3 gigabytes, the 860 EVO can use an additional 9GB Intelligent TurboWrite region, increasing the total SLC buffer to 12GB.

While the performance improvements offered by the 860 EVO are only slightly better than its predecessor, one place where there is a huge difference between the two is endurance. A measure of endurance for storage is TBW (Total Bytes Written). Like a warranty, storage may easily exceed the listed TBW, but the TBW figure gives you an expectation of how long a drive should last.

And this is an area that Samsung has really worked on with the 860 EVO. A 2TB 850 EVO drive had a TBW of 300TB (which, over a five year warranty period works out at about 160GB per day), but the 860 EVO raises this by eight-fold to a whopping 1,200TB (or something in the region of 650GB per day over the warranty period).

This massive increase in TBW makes it perfect for those who regularly churn through huge amounts of data.

The 860 EVO series is offered in three flavors:

  • 2.5-inch form factor for desktop PCs and laptops
  • M.2 drive
  • mSATA for ultra-slim devices


Performance and endurance are identical for all three form factors.

The benchmark testing I've carried out on the 860 EVO shows it to be ever so slightly faster than the 850 EVO, but in reality, it's impossible for me to see a real-world difference between the two drives. However, the much-improved overhead it offers in terms of endurance makes it compelling for those who work with lots of data (video and VR data come to mind).

If you're a data hog looking for performance and a high level of reliability, this drive is well worth taking a look at.

John McAfee: The hero we'd like, not the one we have a tendency to merit

As our electoral leaders show they will botch knowledge security in new and sudden ways in which, AN unlikely figure steps up with sage words.


What's the name of today's industrious generation? no matter it's, we'd  trust dynamical it to the Overts or the Ultra-Gregarians or Generation Flasher. whereas our peers wring their hands at the infosec and private privacy state of affairs we’ve forced these youngsters to inherit, kids} went ahead and did what children do: Ignore the matter and devour wherever they left off in GTA. However, their infosec apathy does not offer Maine the creeps; i am rather more afraid that a giant chunk of my generation has set the instance.

Banking knowledge, health care knowledge, searching patterns, tax returns, your medically measured puffiness circumference -- it’s all been taken and place up for grabs on the ever increasing, pulp-named dark internet. Angry journal posts and magazine op-eds aside, we’ve merely become hardened.
[ additionally on InfoWorld: John McAfee needs to avoid wasting U.S.A. from the NSA | "Google search on steroids" brings dark internet into the sunshine | For a clownish war the school industry's shenanigans, purchase Robert X. Cringely's Notes from the sphere report and follow Cringely on Twitter. ]

Section 215 of the subject Act, one in all the worst offenses against national privacy by our own government during this country’s history, expires, however we have a tendency to barely raise our collective brow. at intervals twenty four hours, it’s back on the books with very little clarification aside from teenage-style whining:

    “Well, we have a tendency to didn’t grasp what else to try to to.”

    “Those NSA guys wouldn’t shut up concerning it.”

    “Debate it? however that takes therefore long!”

A very necessary date

Then we discover out why our pols didn’t want debating: they are too busy planning philandering sessions ... and that they would like additional time to create certain it's all accurately recorded on-line. lay eyes on the high-level analysis of a recent Adult FriendFinder hack:

 upper-level officers at intervals each agency of the U.S. government, to not mention six U.S. state governors and eighteen members of Congress, and myriad aides to identical folks, area unit all members of Adult FriendFinder.

According to identical article, their proclivities spanned the vary of interests, however one common attribute is clear: during this writer’s opinion, all of them exhibited IQs well below the idiot line.

Digital disconnect

How much of mental shellfish should you be to vote for legislation which will directly fund legions of on-line snoopers, then scuttle back to your company and government-owned PCs (used for the bulk of AFF access, per the analysis) to register and raise facilitate cheating on your wife mistreatment your real name?

When you enter the rotunda as a wild-eyed, card-carrying U.S. Senator, is there a little-known law that needs you to hit yourself within the head with a brick? I can’t consider the other clarification that might excuse this level of mental oblivion. What happened to the tried and true tradition of golf stroke a fixer on the payroll?

    Pol: Go get Maine a girl/guy/sheep, Sal, and keep it quiet.

    Fixer: you bought it, boss.

Done -- and unless somebody takes a torch to Sal’s privates, it's fairly anonymous. however {you're|you area unit} soliciting for bother once your personal data and a legitimate mastercard are concerned. What’s worse, solely insane folks appear to worry.

Sure, Tim Cook recently spoke out concerning the evils of knowledge mining and exploit government-sanctioned backdoors in industrial code so our nations’ overworked snoops will return to being lazy brew sponges, and he’s sane (mostly). however solely John McAfee known as out AFF specifically, and let’s face it, John’s brain offers a panorama a lot of incomprehensible than a Japanese giveaway.

John McAfee, voice of reason?

McAfee mentioned AFF throughout a  keynote he remotely delivered to a London audience of infosec professionals earlier on. It in all probability would have garnered a lot of attention if he hadn’t gave the look of Captain Jack Sparrow on his 1st day of rehab. Also, his hand was buried in his pants pocket, in all probability not jiggling his automobile keys (totally true).

Given my history, you’d suppose that wouldn’t have bothered Maine, however I didn’t droop with John even back within the day. And decision Maine quaint, however i feel you save your happy endings for occasions aside from address engagements. However, out of the mouths of nutbars ...

McAfee preached against government-enforced snooping, however he known as out AFF because the most dangerous example of privacy loss in recent months, so much worse than monetary breaches as a result of it unfolded a giant chunk of our upper class to blackmail. John’s not upset that our pols area unit cheating on their spouses; given his record, he can’t be. He’s upset that a veil has been upraised and also the product behind it area unit currently obtainable to the best bidder.

Is that why we have a tendency to now not care? The leather-thonged, ball-gagged rabbits area unit out of the hat, therefore why still create a fuss? In John’s words: "Privacy creates a barrier through that conflict is strangled."

It's ugly, worrisome, and sadly true, a minimum of for several folks from John’s generation and mine. perhaps ensuing generation is correct to ignore the matter. Stride into the digital landscape, broad body part and apple cheeked, and let your freak flag fly. That’d be a brave new world, however it’ll take an extended time before a chilly War greybeard like Maine will get his head around it.
