Samsung 840 EVO mSATA Gets Long Awaited EXT43B6Q Firmware, Fixes Read Speed Issue

Subject: Storage | October 1, 2015 - 05:42 PM |
Tagged: Samsung, firmware, 840 evo, msata

It took them a while to get it right, but Samsung did manage to fix their read degradation issue in many of their TLC equipped 840 Series SSDs. I say many because there were some models left out when firmware EXT0DB6Q was rolled out via Magician 4.6. The big exception was the mSATA variant of the 840 EVO, which was essentially the same SSD just in a more compact form. This omission was rather confusing as the previous update was applicable to both the 2.5" and mSATA form factors simultaneously.

The Magician 4.7 release notes included a bullet for Advanced Performance Optimization support on the 840 EVO mSATA model, but it took Samsung some time to push out the firmware update that enabled this possibility. We know from our previous testing that the Advanced Performance Optimization feature was included with other changes that enabled reads from 'stale' data at full speeds, compensating for the natural voltage drift of flash cell voltages representing the stored data.

Now that the firmware has been made available (it came out early this week but was initially throttled), I was able to apply it to our 840 EVO 1TB mSATA sample without issue, and could perform the Advanced Performance Optimization and observe the expected effects, but my sample was recently used for some testing and did not have data old enough to show a solid improvement with the firmware applied *and before* running the Optimization. Luckily, an Overclock.net forum member was able to perform just that test on his 840 EVO 500GB mSATA model:

Kudos to that member for being keen enough to re-run his test just after the update.

It looks like the only consumer 840 TLC model left to fix is the original 840 SSD (not 840 EVO, just 840). This was the initial model launched that was pure TLC flash with no SLC TurboWrite cache capability. We hope to see this model patched in the near future. There were also some enterprise units that used the same planar 19nm TLC flash, but I fear Samsung may not be updating those as most workloads seen by those drives would constantly refresh the flash and not give it a chance to become stale and suffer from slowing read speeds. The newer and faster V-NAND equipped models (850 / 950 Series) have never been susceptible to this issue.

Samsung 840 EVO Standalone ISO Updater Now Available

Subject: Storage | April 28, 2015 - 12:44 PM |
Tagged: TurboWrite, tlc, ssd, slc, Samsung, 840 evo

For those of you following the Samsung 840 EVO saga, last week we saw the release of Magician 4.6. Samsung was initially throttling downloads and firmware update rates, but those limits appear to have been lifted as of this morning. Another thing we noticed this morning was the inclusion of the standalone ISO updater for those who are otherwise unable to run the Magician software (i.e. Mac users):

EXT0DB6Q ISO.png

For those on laptops or other devices with no optical drive, I've confirmed the ISO can be used via USB if placed there with a tool such as Rufus.

Note to Linux users:

There was an early report of complications from a user who was running a full disk fstrim during boot, where that operation was causing errors (corrected once that operation was disabled). It should be noted that full disk TRIM operations are redundant so long as the OS is issuing TRIM on-the-fly during regular file moves / deletions. This may be an issue with queued TRIM handling of the new 840 EVO firmware. If not reproduced / corrected by Samsung, the Linux devs may be able to add this firmware revision to the queued TRIM blacklist to possibly fix the problem on their end.

Note to mSATA 840 EVO users:

It appears the update does not currently apply to these. I've asked Samsung about this.

Samsung Magician 4.6 and 840 EVO Firmware Released - Downloads Throttled

For those who watched last night's podcast live, I predicted that Samsung would be posting their 840 EVO Firmware and new Magician 4.6 software 'soon'. Turns out that 'soon' was actually this morning, but there's a catch - Samsung decided to limit the daily downloads:

If you went to the Samsung SSD Download Page and got the above error, don't fret, there are a few mirrors out there:

I downloaded from these three sources and at the time of this posting can confirm all three are identical to the Magician 4.6 download available from Samsung.

Once installed, you *should* be able to use Magician to update the firmware on your 840 EVO and (hopefully) see its performance come back to where it should be. There have been some reports of users unable to update, but that appears to be Samsung's servers being hammered and Magician's default / timeout is to report that you are on the latest firmware. Restarting Magician may force it to re-check and get the update.

Linux and Mac users are not yet able to update as the ISO updater has not been released for the new firmware. Those capable can update their Linux or Mac 840 EVOs connected as a secondary drive under Windows with Magician 4.6 installed. Also, if you're running Linux and happen use fstrim during boot, read this post prior to updating.

Introduction

The tale of the Samsung 840 EVO is a long and winding one, with many hitches along the way. Launched at the Samsung 2013 Global SSD Sumit, the 840 EVO was a unique entry into the SSD market. Using 19nm planar TLC flash, the EVO would have had only mediocre write performance if not for the addition of a TurboWrite cache, which added 3-12GB (depending on drive capacity) of SLC write-back cache. This gave the EVO great all around performance in most consumer usage scenarios. It tested very well, was priced aggressively, and remained our top recommended consumer SSD for quite some time. Other editors here at PCPer purchased them for their own systems. I even put one in the very laptop on which I'm writing this article.

An 840 EVO read speed test, showing areas where old data had slowed.

About a year after release, some 840 EVO users started noticing something weird with their systems. The short version is that data that sat unmodified for a period of months was no longer able to be read at full speed. Within a month of our reporting on this issue, Samsung issued a Performance Restoration Tool, which was a combination of a firmware and a software tool that initiated a 'refresh', where all stale data was rewritten, restoring read performance back to optimal speeds. When the tool came out, many were skeptical that the drives would not just slow down again in the future. We kept an eye on things, and after a few more months of waiting, we noted that our test samples were in fact slowing down again. We did note it was taking longer for the slow down to manifest this time around, and the EVOs didn't seem to be slowing down to the same degree, but the fact remained that the first attempt at a fix was not a complete solution. Samsung kept up their end of the bargain, promising another fix, but their initial statement was a bit disappointing, as it suggested they would only be able to correct this issue with a new version of their Samsung Magician software that periodically refreshed the old data. This came across as a band-aid solution, but it was better than nothing.

Read on for our full evaluation of the new firmware and Magician 4.6!

    1. Just a quick question regarding DirectX 12. I’m planning to buy a new graphics card soon but I want a DirectX 12 card for all the fancy new features so I’m considering either the GTX 970 or 980, the question I have is are these real DirectX 12 cards? Since DirectX 12 development is still ongoing how can these cards be fully DirectX 12 complaint?

Samsung Promises Another Fix for 840 EVO Slow Down Issue

Subject: Storage | February 20, 2015 - 06:21 PM |
Tagged: tlc, ssd, Samsung, 840 evo

Some of you may have been following our coverage of the Samsung 840 EVO slow down issue. We first reported on this issue last September, and Samsung issued a fix a couple of months later. This tool was effective in bringing EVOs back up to speed, but some started reporting their drives were still slowing down. Since our January follow up, we have been coordinating with Samsung on a possible fix. We actually sent one of our samples off to them for analysis, and have just received this statement: 
 
In October, Samsung released a tool to address a slowdown in 840 EVO Sequential Read speeds reported by a small number of users after not using their drive for an extended period of time. This tool effectively and immediately returned the drive’s performance to normal levels. We understand that some users are experiencing the slowdown again. While we continue to look into the issue, Samsung will release an updated version of the Samsung SSD Magician software in March that will include a performance restoration tool.

A look at the reduced read speeds of stale data on an 840 EVO which had the original fix applied. Unpatched drives were slowing much further (50-100 MB/s).
 
So it appears that Samsung is still looking into the issue, but will update their Magician software to periodically refresh stale data until they can work out a more permanent fix that would correct all affected 840 EVOs. We have not heard anything about the other TLC models which have been reported to see this same sort of slow down, but we will keep you posted as this situation develops further.
