Dick Fagballzson posted:My 730s will still be humming along nicely years from now while your EVOs are in the dumpster. This is a performance bug, not a "toss them in the trash before they die like cheap junk" problem. If you really believed your own bullshit you'd insist on nothing less than SLC flash since it enjoys bigger advantages in performance and write endurance over MLC than MLC does over TLC. Also despite all your  the reason MLC and TLC are cheaper isn't cutting corners on quality, it's literally just that you can pack about 2x or 3x as many bits into the same number of storage cells of identical (or nearly so) design and quality standards. The EVO's whole claim to fame is that it operates a decent sized chunk of its "TLC" cells in SLC mode to quickly accept incoming writes, up to the size of the SLC buffer.

Unlike the system building thread, this thread is much more geared to "Just buy this, 99% chance you'll be happy, now stop bothering us."

That's why there's a deals thread in Coupons and Deals for that kind of stuff. And for almost all consumers, merely having an SSD at all is so much better than a hard drive that the difference between a mediocre SSD and the best SSD is almost entirely unnoticeable. Updating OPs is a lot of work, and Alereon erred on the side of a steady recommendation so that his frequent updates would be manageable. Lots of drives were left out, but virtually none of them did anything the 840 EVO doesn't. v  v-- Anyhoo, this 840 EVO bug thing comes at an odd time for me. I literally just switched my laptop over to a 250 GB 840 EVO mSATA.

Me too: my 500GB 840 EVO arrived a week ago. So far, I'm very content; getting it for $125 out of pocket ($200 on sale, $75 gift card from selling something I got for free) definitely helps offset news of possible problems.

I was about to get the 500GB EVO, but decided 256gb is plenty, and upgrade to an 850pro and not having to deal with this. Even better, it was like $60 cheaper than the 500gb 840 EVO, and its got all those extra niceties, of being an 850 pro. That being said, it does sound a lot like some kind of software problem that is likely solvable. It comes down to whether or not Samsung wants to dedicate software engineers to fixing a likely complicated algorithm problem on a soon to be obsolete product line? I expect they will, the SSD part of samsung seems to be pretty serious about the quality and reputation of their products. Shanakin fucked around with this message at 17:43 on Sep 13, 2014 |

The MEX controller in the 840 EVO is the same one as in the 850 Pro. I'm sure they have incentive to track it down, at least.

That's true, but I understand they had to redo a lot of the firmware to optimise for v-nand, and there's been no cases of it appearing on the 850s as of yet (although they are still fairly new to the market). In my case, if, in fact the 850s do also suffer from the error, it is, as you say pretty large motivation for them to fix that ASAP, and I've got a pretty awesome SSD otherwise. If not then I've got a pretty awesome SSD. The 500gb would be nice, but honestly by the time I need that much, I'm hoping the cost of SSDs will have dropped somewhat further, and I get to put that $60 into something else.

Regarding Canadian prices, is $150 and $280 a good price for Evo 840 250GB and 500GB respectively? (http://www.memoryexpress.com/Products/MX47587, http://www.memoryexpress.com/Products/MX47588) Also, if I already have a 120GB SSD, could I cheap out and get another 120gb ssd, or is it just better to sack up and get a 250gb drive? EDIT: If I already have windows on the 120GB SSD, is there anything that I need to do regarding just adding a new SSD? Assume that I am functional retarded about this stuff.

Drewjitsu posted:Regarding Canadian prices, is $150 and $280 a good price for Evo 840 250GB and 500GB respectively? Price per GB for 120GBs is getting pretty bad (relative to larger sizes: 72 US cents per GB [120GB 840 EVO] vs. 52 US cents per GB [250GB 840 EVO]) these days to the point that I'd only think it's worth it if you're strapped for cash and don't already have an SSD at all (for at least OS/most common apps). Depending on the model of the old SSD, it may be worthwhile to move your OS over since chances are the 840 EVO has better performance (unless this newly found issue turns out unfixable with firmware) and your OS/common apps will probably benefit more than games or whatever your were going to put on the second SSD. I don't think you need to do anything special after connecting it (except you'll still want to get Samsung Magician and follow OP directions with that), but I'd let a thread regular confirm. bUm fucked around with this message at 21:51 on Sep 13, 2014 |

This EVO news is depressing, everything else that doesn't have a bad reputation is enthusiast stuff that costs a fair bit more, the Intel 730 I was eyeing up is £100 more for the same amount of storage (500GB)

Hey guys, I just installed a Samsung 840 Evo 250 GB drive and reinstalled Windows 7 Pro x64 onto it. Do I need to install whatever is on the disk that came came with the drive or should I just run the old "fsutil behavior set disabledeletenotify 0" command in the command prompt to enable TRIM and put the disk in a drawer and forget about it?

GreatGreen posted:Hey guys, I just installed a Samsung 840 Evo 250 GB drive and reinstalled Windows 7 Pro x64 onto it. Pretty much ignore the disk, download Samsung Magician, use that to see if your firmware needs updating and enable RAPID. Don't do any of the OS optimizations, though. They're really stupid settings that don't actually help. If AHCI was enabled in the BIOS when you installed Windows 7, it should've automatically detected that it was being installed on an SSD and enable TRIM accordingly. But you can re-run the Windows Experience Index system assessment again to be sure.

Ok so I installed Windows 7 with my BIOS in IDE mode like an idiot. However, I followed the steps to reenable AHCI in Windows 7: 1 change setting in registry 2 change setting in BIOS and the Samsung Magician is still telling me AHCI is disabled. Any suggestions before I reinstall Windows 7 again? edit: I've decided to go ahead and reinstall Windows 7 Pro x64 with AHCI enabled in the BIOS. Hopefully that will fix the issue.

Before I went to the trouble of a flatten/reinstall, I'd make SURE AHCI is actually not working - the easiest way that I know of is to run CrystalDiskMark and compare the last two results(4k and 4k queued, 32 deep). If AHCI is working, the 4K queued result will be significantly improved over the vanilla 4K - if it's still in IDE mode, the numbers will be the same, since command queuing only works when when AHCI is functioning properly.

Is there anything you can do besides just enabling AHCI mode in the BIOS and changing that registry value from 3 to 0? Are there any specific drivers I should go download and install first or something? Can installing the AHCI during a windows installation fix the problem? I'm using a Gigabyte P55-UD3R motherboard and the drivers download page for that board has an AHCI driver specifically for injecting into a fresh Win7x64 install. How likely is that to solve the issue you think? Update: I reinstalled Windows 7 and finally got AHCI working. I'm using a Gigabyte P55-UD3R motherboard and apparently I had to download the SATA AHCI drivers from Gigabyte's website and inject them into the Windows install by pressing F6 at the point where you choose your OS partition. Injecting the drivers at this point will create a 128 MB partition that the drive uses for AHCI I guess, but whatever it does it works. If you're using an SSD and aren't using AHCI mode, I'd highly recommend seeing if you can activate it. I did a few speed tests and the drive is a loooot faster now. edit: god drat this PC feels fast now, holy poo poo. GreatGreen fucked around with this message at 04:04 on Sep 15, 2014 |

So many butthurt people in this thread who bought EVOs. When you buy a drive that's basically a bunch of USB flash drives held together by some glue and a dream, this is what happens. Xenomorph posted:SSD bashing aside, recommending anyone use RAID 0 for anything other than a temporary/scratch drive rubs me the wrong way. Why? So it has two failure points. It's still probably more reliable than most any mechanical hard drive. And it's fast, which I thought was the whole point of getting an SSD in the first place. It sounds like you just lack the courage to step up to baller level SSD speeds. (USER WAS PUT ON PROBATION FOR THIS POST)

I've got an application that takes 22 minutes to generate 50MB files on my Samsung 250GB EVO and takes 26 minutes when it writes to a RAM drive. This seems odd, I would of thought the RAM disk should be a little faster than the SSD.

Well so far its unconfirmed by any place that I'd trust. There seem to be some forum articles on it, but nothing else. I've had my 256 for...nearly a year now I think. Maybe 9 months or so. Single Win 7 install, lots of static data in a few folders from immediately post-install, and I've never seen anything resembling what they are saying. So its either a) no trim equals bad or b) bullshit/something else not the drive. Either way, I wouldn't sweat it.

Theory: Their storage midlayer driver is causing the bottleneck? If not, then I guess spurious interrupts or some other crap. Wild dart throwing here. Edit: Someone without RAPID enabled should be able to refute/prove that fairly quickly, I imagine. Or someone that uses multiple EVO drives, but I'm unsure.

From what I was reading on overclockers, the problem with the EVOs are specifically limited to the 128/250 GB models. They have found that a secure erase, meaning using a specialized app to totally zero out the drive, will restore performance to brand-new-drive levels. Most people who are experiencing the issue are taking an image of the drive, using another program to secure erase the drive which zeros it out, then they reapply the image back to the drive making sure that the alignment is correct. This seems to fix the problem. However, it has not been determined whether or not this is a short-term or long-term fix. People don't know if the drive will eventually go back to being slow. Well, "slow" for an SSD.
