Samsung 840 EVO read speed drops on old-written data in the drive - Page 296

I kind of gave up. I treat all drives as if they could go bad at any moment. To not have to worry too much, I just back up a lot, and not just data, but also full backups so that I wouldn't ever have to reinstall anything.

This also is in some way nice because I stopped worrying completely about how to treat an SSD best. I don't do anything like disable hibernate or use a HDD for user files etc. I just don't care if the SSD is used "too much" or not. I bought it to speed things up, and the more it is used and written to, the more it does its job of speeding things up.

Now, with the Samsung problem here being about speed, they managed to find exactly the only type of problem that still is annoying for me. biggrin.gif

Contrary to what my few previous posts may indicate, I was not trying to just rile people up here, even if I feel we all should be (against Samsung, of course).

What I was trying to do was balance the posts supporting Samsung unequivocally with equally valid points of view that many here thought incredulous, at first blush. (And eventually, other posters validated my unlikely claims in later posts). Not simply to sway opinion one way or another, or worse, troll, but rather to show that there are always at least two points of view. The net result as many have been saying all along is that we just need to wait to see if this is really a fix and I wholly agree with that. But I can't help but go back to the facts that Samsung hasn't officially said anything about this and that was the reason for me posting the last couple of days (because to me, their intents are obvious and not above board).

Not only are the original tlc 840 drives still being ignored for this issue, but, as a poster mentioned in the last page, the new firmware and magician didn't fix (I think it even hurt) the performance of their EVO drive too.

What my posts are mainly here to do is open the eyes of the younger (and even some older) members here that where big money is concerned, ethics/morality and professional codes of practice go out the window. And the bigger the company, the more unscrupulous their methods can be to swindle the customers of the service or product they thought they bought and paid for.

Yes, time will tell one way or another. And, I don't want to be right here, I too have multiple EVO's to service for myself and others.

But, I have opened the eyes of a lot of people here and that was my goal. Thank you to all that supported my posts one way or another. In this day of instance ridicule, it is sometimes harder, not easier to proclaim truths and facts based on simple observation of the world around us. Especially when those facts seem far-fetched to the innocent.

The smell test usually works. Especially when you've smelled that stench before and it can even work to keep the company honest too - if they know they're being observed under a microscope because of their checkered past. But when people come and support a company blindly (even if the individuals intentions are just), all we are doing is giving corporations a key to our wallets. And getting laughed at all the way to the bank, right to our faces.

I did not offer conspiracy theories as some claimed, nor am I totally uneducated or an expert in all things 'computers'. But I do know what makes a computer work and can extrapolate that information to what can be done with the basic building blocks. My posts showed one such outcome.

Bottom line, critical thinking is a requirement. The only one you can trust exists between your ears. But learn to look and (actually) see, without bias or prejudice one way or another, before you take a stance.

It takes courage to come out and make statements like this in the interest of "burying the hatchet" with other members of the OCN community.  I have made disparaging remarks about @TwoCables and got the thread temporarily locked by Phil in the past and later realized that it was counter productive in the end.  I have also given @Palorim12 a hard time in the past.  I have since made up with them and apologized.  We are all here with the common interest of finding the truth and while we have different opinions and points to make, we are all really here for the same reason.

 

I know how you feel about making recommendations to buy 840 EVOs to others because I did the same thing and feel a sense of responsibility to them for getting them into this mess.  It's not a good feeling.

 

@trparky , As much as it pains me to say, I think the 850 PRO and EVO are sound because of the fact that the structure of NAND design is radically different and built on a 40nm node so that I honestly can't see how they will have this issue.  And their performance is pretty darn good too.  Personally I have switched to the SanDisk Extreme Pro because you can RAID0 them and their software can see each drive through the RAID, update FW and give full performance and SMART data while in this configuration.  You can find them on sale for comparable prices at times but I see that their prices swing wildly from day to day for some reason.  I also like the Crucial MX200 for price and performance.

For instance... this happened to Samsung's Mobile Device Division. Apparently a year or so ago Samsung's Mobile Device Division wasn't doing so hot, hence the reason why the Galaxy S6 had such a radical redesign, they were getting butts kicked by the competition. Well, when it came down to who got the blame, a lot of the executives in charge of the division took either a major cut in pay or were completely let go. A vast difference between what would happen in the USA and other western companies. What happens in western companies? Oh yeah... the lower level people who probably had nothing to do with the failing product are let go and the executives are given fat fat bonuses.

If you ask me, that's rewarding failure. Oh yeah sure... go ahead, fail. We don't care. Here's a fat stack of cash.

If you ask me, if western companies operated more like Asian companies in which the executives are held responsible for their mess-ups we wouldn't have nearly the kinds of corporate failures that we have in the western world. Maybe we wouldn't be in an economic slump like we are.

Seppuku is the act of self disembowelment, with the longer cut showing more courage. Then ur buddy chops ur head off,. Bit different from falling on a sword. Figuratively and literally.

Do you know why Samsung's phone division was suffering? The S5 SUCKED. It had battery overheating issues, camera issues, the "water proofing/resistance" failed miserably and the list goes on. It was another flawed design (timing?), I bet a lot of people quit samsung after that too. The s6 and $100 more for the s6 edge (which is useless lol) are drastically different in only one major way, they dropped the proven qualcomm snapdragon processor for an in-house built one to save money, like how they do (I think they may have dropped the removable battery too, don;t remember)
Good luck guys, your engineers are top notch! Penultimate even!

It takes a lot of guts to disembowel yourself like that!  :D

 

I got the S5 Active, which IS waterproof, and quite cool with its built in ruggedness and camo look.  I've had absolutely no problems with it with the battery, which along with the 128GB micro SD, is replace/swappable.  I also have the Neo 2 watch with the built in camera that is equally cool.  I can take/make calls from the watch and remote control each device from the other.  It's great when you loose one or the other and nobody else is around to call you to help you out.

That is very cool. I'm glad Samsung didn't screw you again. But check the net, there are s5 horror stories floating around. My stupid s4 didn't download lollipop, and i was annoyed, but then i realized those were my settings, now I don't know if I want it. My phone wallpaper is black with a silver batman bat. I don't want everything turning white. Is it worth the switch to lollipop?

In other news: If sammy wasn't lying... big if... then today is the latest the checks should be in my mailbox.

P.S. alot of guts... dude no! why? you have dishonored millions who will come to you in the night with those eerie white masks with a red stripe like i how i hear japanese ghosts u pissed of do eek.gif

P.P.S. Hey you said S5 active, that's not the regular S5 - that's like comparing a pro to an evo... et tu brute?

Here are some benchmarks from an 840 EVO that my brother owns. I installed the firmware on his SSD the week it was released.

 


I'm not seeing any kind of read speed performance degradation here. It's all relatively consistent speeds across the board.

My disembowelment comment was a pun (play on words.)  What are they teaching you Cannucks these days???

 

I think I had no choice for lolipop, it just did it on its own in the dark of the night.  Didn't screw anything up but changed the "look" of things which pissed me off.  Now if I could only figure out how to tether on my unlimited data plan....whistle.gif  I did put my sim card in my old jailbroken iPhone 4 and that still tethers but I am hesitant to root the Samsung.

 

Yes, it is the badass version of the S5.  When my Marine dad showed me his regular S5 I was like, "What, you didn't get the camo indestructible version?!?!"

 

Good luck on your refunds...

Good luck rooting the Samsung if it has a locked bootloader like most carrier branded versions do. One wrong move and you're in Bricked City.

Looks good, did you take a before graph?  Excuse me if you did, this thread has become so long.

post #2960 of 3279

No, I don't have Before graph. All I have is the one I did today.
