Looks like rumor has it the firmware fix will come out mid-October. Are 840 EVO firmware updates non-destructive? Not sure if I should wait or purchase one now based on that. I'd be willing to roll the dice on Crucial but it has to be mSATA and the M500s or whatever look like they suck next to the MX100s.

Probably won't know until Samsung officially announces anything, and what the issue actually is, and etc. The one firmware update I did was non-destructive, but who knows what the future holds.

That being said, I've happily installed firmware updates on my evo before with no issues.

My Evo didn't come with the Samsung Magician installed due to being a OEM kit, but there shouldn't be any problems just installing the Magician software from their site, right? At least it doesn't mention any difference between the OEM and other kit.

That's what I did. That said, I'm not using RAPID because it would break and disable itself every time I slept my laptop. But I'm pretty sure that's a one-off problem rather than an inherent problem of downloaded Samsung Magician.

I use downloaded Magician because I didn't put an optical drive in my computer. I wouldn't expect there to be a difference other than downloaded being a newer version

If you install from the disc it will find updates online anyway, which means installing from the disc isn't really any better unless you don't have your network driver installed yet or something.

So, uh, I updated the BIOS, installed Windows, ran Windows Update a million times, started getting everything rolling again. Remembered to install Magician from the OP and it tells me AHCI isn't enabled. I thought for sure that I did it, but maybe I did it before updating my BIOS? So... that could be a problem. I tried turning it on in the BIOS settings but that just makes Windows (7) bluescreen when it tries to start. Changing it back to IDE mode made it start working normally again. Am I just doomed to reinstall Windows again?

My local computer store has Samsung 840 Pro Series 256GB for $169 (canadian $). The 850 of the same capacity is $220. Does the bug affect the 840 PRO as well as the EVO? How much faster is 850 vs 840? This deal seems quite nice to be honest. Found this chart: http://techreport.com/review/26701/samsung-850-pro-solid-state-drive-reviewed/8 If techreport is correct, then the difference is not that big, unless the drive is also affected by the bug, in which case  .

I bought my dad a 840 EVO to throw in a brand new Dell. Someone gave me the impression that Samsung's data migration program would be able to clone the OS drive from Dell on the to SSD and everything would be good to go. That didn't seem to work. The SSD OS just hangs at one of the Windows (8.1) loading screens (forget if it was before or after the user account login). I'm not surprised, as the Samsung ran without a restart and indicated it would not be able to copy locked files. Anyway, my plan is to have him use Dell's backup software to create a Windows re-install thumb drive, then start fresh on the SSD. Will that work (any issues booting to the SSD w/ Dell's UEFI BIOS)? Any other course of actions to consider? Splinter fucked around with this message at 21:58 on Sep 26, 2014 |

I've used Macrium Reflect Free to clone a live install before (it was win7 not win8 but it shouldn't make a difference). I've also used CloneZilla to image drives from a boot disc but it's not as user friendly. There are other options but those are the ones I've used. If you need to, the Windows backup and restore should also work, it's a little clunky, though.

I've currently got a Crucial SSD that runs fine, but at 128GB I never have any space. I planned on grabbing an 840 EVO soon but is it smart to wait until the firmware comes out on the 15th? Will I notice any problems between now and then?

The bigger hangup would be confidence in Samsung fixing it and, in the process, not screw things up entirely (always a concern with firmware) or having permanent (unavoidable) decrease in some metric (lifespan or whatever) with how it was fixed. That probably won't be known until some time has passed after the firmware fix is deployed. If you're ready to pull the trigger, you should be fine through to the firmware fix. How pleased we'll be with the firmware fix waits to be seen.

I was told this might be a good place to post about having a 256 GB 840 Pro for sale. I'm asking $150, but I'm flexible on the pricing. It's less than a month old, with fewer than 2 hours of operational use. Love the drive, but with a single bay laptop, I need something bigger. http://forums.somethingawful.com/showthread.php?threadid=3664324&pagenumber=1#lastpost

Anandtech has uncovered widespread fraud with Crucial SSDs: The claimed power-loss protection feature in client drives does not exist. Both Micron enterprise drives and Crucial consumer drives have a capacitor array on the PCB, but this array doesn't hold enough energy on consumer drives for data "in-flight" to be written before the drive shuts off. This is incredibly frustrating both because I know people in this thread and elsewhere bought the MX100 because of the claimed power-loss protection, and because Kristian from Anandtech specifically asked Micron about this and it was not disclosed at that time Basically, Micron's argument is that there's enough power to finish writing any cells that are currently being programmed, which reduces the chance of the drive itself bricking due to a power-loss, but just like any unprotected drive your data may be unreadable or the filesystem may be left in an unmountable state, and any data you were saving DEFINITELY won't be there. Train analogy: Crucial claims their engines have backup power and can get the train to the destination even if they run out of gas. It turns out they just unhook all but the first car and abandon the others to their fate, and then go "but at least we didn't lose the whole train, right?" When combined with the broken TRIM and overall firmware quality issues on the M600/MX200(?), I think we've confirmed Crucial is the new OCZ and nobody should ever buy their drives. This isn't an honest mistake, this is just Crucial intentionally lying to and dicking over customers. Also, I'm officiating a wedding this coming weekend so I have less time to devote to the forums right now. I'll try to keep up but I'm prioritizing things. Sorry!

Bob Morales posted:It appears to perform as bad as the MX100   On the left is the sustained write performance of the various Samsung 840 Evo models, on the right is the Micron M600 256GB. The 840 Evo has two performance plateus: gently caress-off fast because you're working in SLC cache, and normal speed because you're working in TLC main memory. The M600 has three: gently caress-off fast in the SLC cache, normal speed in the MLC, then gently caress-off slow because the drive is fighting for time to empty its cache with the writes you're doing. Even though the MLC NAND in the M600 256GB is a good 25% faster than the TLC in the 840 Evo 250GB at sustained writes, it actually comes in less than half as fast because it spends half its time loving with the cache. Look at TechReport's Mean Service Time results, particularly in comparison with the Samsung 840 Evo, which has to do most of the same management. I feel weird singing the praises of Samsung's firmware while we're still waiting for a fix for the slowdown issue, but I mean goddamn look at that graph on the right up there that firmware is like half-done!

The SSD in my laptop is a MZMTD256HAGM that isn't recognized by Samsung's magician software, but is supposedly based on the 840 EVO. Given that these drives aren't recognized by the Samsung software, doesn't it seem like they probably won't get a firmware update?

I ran DiskFresh on my 500GB 840 EVO, then ran HD Tach again. All those weird sub-100MB/sec spots are gone. The program is supposed to read every byte of data and re-write it back to the SSD. It's like running a defrag to freshen the data, except this program will re-write everything, not just fragmented files. Yes, it uses up a write cycle. So my drive's lifetime writes went up by 0.5TB, which may not be a whole lot, in the grand scheme of things. I'll probably run DiskFresh again after updating the SSD's firmware in October.
