250GB Samsung 840 SSD has gotten slower after format

[pong lenis]

I've been using my SSD for 3-4 months and it has always kept the same speed. But after I formatted my SSD yesterday(reinstalled the Operating System on it), boot time suddenly became much slower. And when I say suddenly, I mean right before I formatted the SSD the boot time was exactly the same as it was when I bought it, and right after I formatted the SSD boot time is now doubled. For example I used to see the windows logo for about 3 seconds, now it lasts about 7 seconds. And after I formatted I followed the exact same SSD tweak guide that I followed the first time I installed the SSD, and it's the same Operating system and the same drivers, so what could account for this very sudden change in SSD boot time?
I checked the speed with CrystalDiskMark and it's very close to what it was before (sequential: 520MB/s Read, 250MB/s write), so what's the problem?

If you haven't got it yet, download the latest version of Samsung Magician. Version 4.0 is very good. It will optimize your OS for different states, i.e., performance or reliability.

Samsung Magician already came in a CD with the SSD, and didn't I already mention I made the exact same tweaks that I had made before formatting?

maybe you missed a step?

without knowing what exactly you did, it's hard to know what to suggest or what you've done already.

Use crystalinfo. That will tell us exactly whats going on. gl

Have you installed the latest (or at least recent) Intel RST drivers?

What options did you used for formatting?

OK - but what version? The CD could be the 3.X version. There's a big difference.

Just curious - why did you reinstall the OS when it was working well?

All I did was press the format button(the eraser) in the windows installation. Then I installed windows, then I installed all the exact same drivers that were installed before formatting, and then I applied the exact same tweak guide I had applied before(http://www.overclock.net/t/1133897/windows-7-ssd-tweaking-guide), and installed the same anti-virus.

Is there any way to find out the health of the SSD? SSDlife doesn't recognize my SSD.

Yes get Crystal Disk Info ,,,, free small app.. will show you everything!!!

When ever I do a clean install on a used ssd I do a SE first with Samsung Magician.
Do to your windows install going on to the ssd there no time for the garbage collection to be done correctly I believe.
It has been posted here many times that you need se to get you drive back to normal.

You can use CrystalDiskInfo. Just make sure you download the portable version. The installations always have adware.

Most of the things in that guide are completely unnecessary for modern SSDs. For normal use you are never going to wear it out, so all those tweaks for reducing writes are a good way of reducing performance as well.

If you created the partition in win7 it will be aligned. Also defrag is automatically disabled for SSDs in win7.

It will take much more than two win7 installs to slow down this SSD. This isn't Sandforce, no real need to SE it all the time, Trim works fine. (Even Sandforce drives don't really need it unless you back them into a corner with lots of incompressible writes where only SE will restore performance)

Reducing writes should have no advert performance effect on the operating system. The idea behind reducing writes is to prolong the SSD life span, and we both know the 250GB Samsung SSD can last over 136 years of 10GiB/day simulated writes before it dies. Tho the less wear you put on it the better (not every single NAND chip is as good as another). Most of these tweaks only keep writes from happening frequently to the drive. To some extent I agree that page filing and super-fetch aren't going to totally wear out your drive like some people think. Tho in the guide, there isn't anything that's being disabled that would have an adverse performance impact (other than super-fetch and page filing). Tho with more than 4GB of system memory, neither should provide a noticeable enough performance improvement to even have them enabled (the guide disables them for this reason, they serve no benefit other than wasting write cycles). The only thing I can suggest, is to check and make sure your SATA controller is set to AHCI in your bios settings (IDE mode doesn't support trim).

We both agree that for consumer workload it would be extremely unlikely to wear out a SSD. Even the 120GB 840 TLC made it to about ~90TiB before its rated cycles were used up. http://www.anandtech.com/show/6459/samsung-ssd-840-testing-the-endurance-of-tlc-nand.

Also the guide shows tweaks of removing cache and temp files off the SSD. I put temp files that I will be working with ON the SSD (essentially use it as a scratch disk). What's the point of spending 10+ times more per GB on a SSD and then not using the speed?

BTW Trim does work in IDE, but you should still have it set to AHCI for better performance.
