Thanks Mortal Raptor!

I think it is actual version 4.5.1.

Upgraded over the top.

I'm still unsure what (if any?) I need to do with the OS Optimization option in it (having one SSD and one HDD) (Win 7 Pro).

Version 4.5.1 is a very welcome release for getting my 850 Pro to enjoy the benefits of the RAPID Mode feature in W7Pro64-bit.

@FanJ: Leaving your settings as is, and try running the integral Performance Benchmark test. Then, change your settings to optimize your SSD instead of your HDD and rerun the Performance Benchmark test again where you will be permitted to compare the results of the two tests in a horizontal bar graph. My tests with and without RAPID were quite informative.

Should we assume that in general, most of your system activities are with your SSD and your HDD is more for long term storage purposes?

Hi 1PW,
Thanks, and sorry for my late reply!
I will have to look at it further (it may be later; sorry).
Yes, you are right about my SSD and HDD.
Thanks again!

1PW · Dec 10, 2014

I also had previously enabled the recommended 10% Over Provisioning.

Enjoy and season's greetings.

Thanks anon.
Although the new version seems to be more for the 850 / 840 EVO and I have the 840 PRO, I installed it over-the-top nevertheless.

=====

I have another question for those of you who have Magician installed; a question that I wanted to ask for a long time.
When I look (for example) in CCleaner -> Startup -> Scheduled Tasks, I see this task:
"C:\Program Files (x86)\Samsung Magician\Samsung Magician.exe" /AUTOHIDE
Do you guys have that task enabled? And what does that task do?

PS: I'm on Win7 Pro 64-bit. The C drive is the 840 PRO, the D drive is an HDD (mostly for storage).

Many thanks in advance.

Samsung To Release Magician 4.6 and 840 EVO Firmware Update — Performance Degradation Fixed At Last?
April 17, 2015
http://www.thessdreview.com/daily-n...update-performance-degradation-fixed-at-last/

It took Samsung a little while, but it appears that they have finally resolved the 840 EVO performance degradation issue. In the process, Samsung has given the 840 EVO an added feature via the “Advanced Performance Optimization” tool. As Allyn puts it, “….so in trying to fix one problem, they have actually added a useful feature to this product line.” It will be interesting to see if this feature is made available for any other Samsung SSDs, particularly the “non-840 EVO” other SSDs that utilize TLC NAND.

The startup entry is just to load Samsung Magician on startup, you can right click the magician tray icon & click remove from startup.

I'm just hoping that this performance optimisation doesn't have to be run regularly to keep the performance of the drive. To update the drive firmware just click the firmware update tab & follow the steps, it will shutdown your PC & when you restart it it will have updated the firmware. Then just run the performance optimisation in the advanced tab.

Before getting into the actual results, I'll post the Q+A I had with Samsung as we were testing. This should explain at least what we expect to see:

Q: The new firmware appears to restore read performance without the need for Magician. How was this accomplished?

A: Samsung revised the firmware algorithm to maintain consistency in performance for old data under exceptional circumstances. Therefore, read performance was restored without the need for Magician. This algorithm is based on a periodic refresh feature that can maintain the read performance of this older data. The algorithm does not affect normal user scenarios (i.e. occasional PC performance degradation due to background work of SSD) or the lifespan of an SSD and can actively maintain its performance without the help of Magician. However, this algorithm does not operate when the power is off.

Q: Are there any functions of the new Magician that are required to keep read performance high?

A: The read performance has been improved by the revised firmware algorithm. If performance recovery is slow in instances where the SSD did not have enough run-time for the firmware algorithm to reach normal performance levels, or similarly, had been powered off for an extended amount of time, the performance can be recovered by using the Advanced Performance Optimization feature in Magician 4.6. This is a supplementary feature to maintain normal performance for a few exceptional circumstances.

Q: What is the upgrade process for those who did not previously upgrade using the performance restoration tool (meaning they are still on the original firmware)? Is it possible to skip directly to this new firmware and not use the performance restoration tool?

A: Users can upgrade to the new firmware through Magician 4.6, without using the performance restoration tool.

Q: Will there be a firmware update for the other Samsung TLC-based SSD models that have also demonstrated this read performance issue? If so, which models and how soon will that firmware be made available?

A: This issue had been reported for the 840 EVO SSD only.

I'm pretty sure Allyn said in the article that as long as you keep the SSDs powered, you won't need the Advanced optimization, and if you do unpower the drive, when you power it, the algorithm kicks in and goes to work. the advanced tool is only if you want the performance immediately after re-powering the SSD.

Firmware update procedure for RAID users is detailed mid-page here.

The firmware alone puts read performance where it should be. The Optimization is not necesary unless you want a bit more performance (the same can be accomplished on a RAID by running some other tools that rewrite old data). One such tool for this is DiskFresh.

Yes running these tools eat up write cycles (1-2 cycles for a full SSD), but that's a small percentage of the available cycles (1000 minimum, but TechReport got >3000 cycles on their endurance test).
