interesting to see how this plays out, that is one helluva stanky drive, perhaps the best consumer drive out right now.
sub'ed
thanks for the heads up.
I recently purchased one, and will be installing it in the next few days.
Thank you , some test before and after flash with old versus new firmware , give me a few minutes.
System used:
Asus P8Z77-V PRO , using Intel native sata 6g controller with Intel driver 11.7 ahci
3770k 4.6Ghz
16GB g.Skill DDR3 2400
Samsung 840 PRO 256GB
Runs are with nothing in the drive ( Empty Drive ) , using intel ahci driver 11.7 , after each run the drive was trim manually to a clean state.
old firmware used was DXM03B0Q
new firmware used was DXM04B0Q

Thanks a bunch for the benches chispy - you just saved me and others a ton of time doing all of that.
Looks like if we want to split hairs, the 4k QD1 reads took a very slight hit. PCMark application loading bench confirms that as well...
Wish Samsung could be a little more descript in what they've done to the fw. If helping dirty-state write is the only tweak, so be it.
Thanks again.
Agreed , i have retest again and getting more or less the same numbers over and over again ( the 4k QD1 reads took a very slight hit = True ) , not much of a difference from the old firmware , writes are somewhat faster by a slight margin and more consistent , very small gain in writes. But overall good firmware , i say give it a go guys :up:. I trust Samsung , my 830 ssds has been going strong since they came out without a hickup. but as you said , it would be nice to know what exactly they did on this firmware. Not bad , not bad at all.
New firmware for the normal 840 as well
will have to apply that tonight
New firmware has fixed the SMART counter for Total LBA Written (F1).
It is longer gets stuck at 2TB on my Samsung 840 TLC drive and seems to be counting normally.
Jury is out on performance. Will have to see after half a dozen runs of ASU.
Anyone with a couple in R0 figure out how to do the update?
Magician won't see them, boot up on my two plextors (in R0) and plugin a single 840 pro, magician does not see it. Cannot initialize drive in windows, man if I have to blow away data not going to be impressed. Sure hope I am just having a Friday morning brain fart. :eek:
Lovely, I just finished testing with the old firmware. Looks like I'm working double time today with the 840 Pro and the Plextor M5 Pro Xtreme FW.
You should be able to create a bootable USB from the Samsung magician toolbox
Then you can change the system to AHCI mode, update the drives, and then switch it back to RAID.
This should not damage your data (but you would still be wise to have a backup ready just in case)
It will not let me download the FW without first seeing a sammy ssd, which it doesn't. I don't have any single drives with windows installed so I am still in R0 with my two plextors.
I've tried to create bootable USB and CDs from the Magician software and the result is once the cd or USB boot, the screen is jibberish. Like its drunk or something - the text is too blurry to make out.
I have other dos boot disk that are fine. Anybody else have this issue?
To flash raid drives, toys is correct - make boot USB, change to ahci, flash both drives, change back. But I cannot get a usable boot USB/cd to work! All my other windows boxes are configured for raid, so attaching one as a slave wouldn't work either. Hmmm. I'm not rebuilding my array for a 3rd time in 2 weeks.
Ah ha, just found the FW standalone download, now I can make the bootable usb.
Magician allowed me to make a bootable usb but when I boot to it in achi mode all I got was an empty blue screen, nothing there and nothing happening.
I had a Samsung tech on the phone while I was on the command prompt that appears after the Samsung screen. I entered the command directly to flash and it gave an invalid argument error, but it said \s is a valid argument. tech said this means that there is an option in the flash missing, bottom line he said they would have to update the FW.
LOL, so we can only update to the new FW via windows? Fine for single drives, not fine for array drives.
Yeah, as it stands I would need to lose my OS to flash. He did say he would be calling me back today but I would be truly shocked if it happens. Tried manual flash in both achi and ide with smart data off in bios with no go.
If we update the drives that are in a R0 on another computer will we loose are R0? If not I will update mine on another computer tonight... But it seems like my R0 is getting better then when I started it left is fresh install with W7 updates and right side is with Steam games added including new Far Cry 3 heavy played for a while and my 4k reads and writes are getting better...

Normally, you can. I've done it with OCZ array drives on another comp many times. However, I think I've seen where the Magician software "knows" it's an array drive and will not recognize it (as a single slave drive drive), even when magician is running in AHCI on another box with an array drive attached as a slave. It's not the fact that Magician can't be run on a box in RAID mode - I have a box running in RAID mode with a single 840 Pro that is NOT in an array and Magician can see it fine. I may be wrong. Feel free to try it.
The new firmware fixes my notebook power test. I wasted 24 hours trying to get it to work and it would error out every time at some point.
Nothing sucks more than running a test for 6 hours and it just say, Nah I don't read this file anymore, :banana::banana::banana::banana: off.
Updated mine on a buddy's system, single drive in IDE mode. No problem that way, but hardly an ideal situation.
dumb question can you update the FW on a SATA II setup?
