Have a Samsung 840 Evo? You need to read this.

I just applied the fix to one of mine, no issues. I can't compare before and after benchmarks because I've only had the drive for a month, but users have reported massive improvements on year-old drives.

EDIT: To be clear, this is for 840 Evo models only. This tool does not apply to 840 "vanilla" and 840 Pro drives.

Thanks for this info please keep me updated as to when they release the mac version of this. I am not experiencing problems with my drive, but I will update the firmware just to see if I get any improvement. Im running OSX 10.10 on a Samsung 840 Evo

To my understanding, the firmware update does prevent the problem from occurring in the future - the performance restoration rectifies degradation in performance with existing data. Much easier than a full reformat.

Thanks for the heads up Mesaone.

All updated without a hitch.

Never got much slowdown but I haven't owned my drive that long. Decided to run the update (mac osx so i booted with a usb stick). Took about 30 minutes on my drive and lost no data, all done. I'm happy

Although I bought my EVO in April I figured to give this tool a go. I noticed an +20% performance increase in both random read & write times and sequential read & write times. Sweet!

Thanks to the OP for this. Wasn't aware. The Mac/Linux version is there now btw.

I also have this same drive(500GB version) and was initially disappointed in the lack of performance that others are gloating about. Then something was brought to my attention, and that is, HOW the data is written will affect the performance in a large way. In my case, I was not doing a fresh install of OS and software. I was loading a drive image from my previous system drive(a 7200 rpm spinner). However, after running the Samsung optimization software(my firmware is already up to date), the performance boost was eye-opening I am finally getting the performance I have been reading about for months Point is; run the included software

Are you referring to Samsung Magician? Yeah, it's surprisingly good. Overprovisioning, firmware updating, OS optimization, drive statistics, benchmarks, etc.

EDIT: I just enabled RAPID mode, which I didn't know was an option. Check these benchmarks, dark blue is before and light blue is after. http://i.imgur.com/IMUKUki.png
