Samsung 845DC Evo model MZ-7GE960EW health
Hello,
I am thinking about my Samsung 845DC Evo model MZ-7GE960EW health, but Samsung software does not recognise it. Any way I can check its health in percentage? |

Health status says "good" but nothing else says "Total LBA Written" but does mention total host writes or total host reads - current worst values 99. |

Like # a lot of Samsung pages before it. I get the same thing # when trying to look up DRAM part numbers. https://www.samsung.com/global/busin...downloads.html While you can see the page the way it used to be, that doesn't necessarily mean you can get a download from here. https://web.archive.org/web/*/https:...downloads.html And, I wasn't surprised at the results (binary screen dump to my web browser). No download there. ******* https://www.samsung.com/semiconducto...ownload/tools/ "Samsung SSD Toolkit for Data center(2) Samsung SSD DC Toolkit is designed to work with Samsung SSD products including PM863, PM863a, SM863, SM863a and PM963 non-customized. This software is not compatible with other manufacturer's SSDs. DC Toolkit Version 1.0 | 2.46MB DOWNLOAD === Linux DC Toolkit User Guide " http://downloadcenter.samsung.com/co...Toolkit_V1.zip It's good to see the version number doesn't change. Inside the ZIP, there exists what could be statically linked Linux executables. Samsung_SSD_DC_Toolkit_V1_x32 Samsung_SSD_DC_Toolkit_V1_x64 Unzip, then chmod 755 Samsung_SSD_DC_Toolkit_V1_x64 sudo ./Samsung_SSD_DC_Toolkit_V1_x64 --list The utility doesn't work with my Samsung drive, but it might work with yours. Using a hex editor, I can see "845DC" as a text string, but that doesn't mean anything. If the executable really understood those drives, the model number would be sprinkled more liberally through the executable. It isn't. You could run that from a Linux LiveCD if you wanted. It doesn't install. Just unpack, chmod, then run. Paul |

Looks like enterprise SSD product users are supposed to use the Samsung
Magician DC software. It can be found at: https://www.samsung.com/semiconducto...ad/enterprise/ They separate the 32- and 64-bit downloads. The 64-bit download from this page is: Samsung_Magician_DC_Windows_64bit.exe @ 3.28MB The Samsung Magician 5.1 download that I have for my Win7 x64 setup is over 14MB in size; however, I don't remember separate downloads for th 32- and 64-bit versions, so the one installer probably has both. There seems to be differentiation between the consumer and enterprise software packages. Sorry, no idea what Samsung intends "DC" to mean. The PM853T is the OEM cousin to the 845DC EVO, and both are marketed as enterprise-grade SSDs with TLC NAND. |

Health status says "good" but nothing else says "Total LBA Written" but does mention total host writes or total host reads - current worst values 99. I'm using HD Sentinel Standard to monitor the health of my SSD and HDDs. While the SMART attribute 241 "Total LBA Written" is shown, it is not selected. Only those attributes that indicate health for an SSD are selected when I look at which SMART attributes the HD Sentinel chooses for my SSD. Not all SMART attributes are applicable to SSDs. The ones the HD Sentinel uses for my SSD (Samsung 850 EVO) a 5: Reallocated Sectors Count 177: Wear Leveling Count 179: Used Reserve Block Count (Total) 183: Runtime Bad Block (Total) 187: Uncorrectable Error Count They have a hardware compatibility page at: https://www.hdsentinel.com/compatibility.php Under the SSD devices, the 845DC is not listed (it appears to have been introduced around 2014); however, that doesn't mean the drive isn't supported. The SMART attributes very likely perform the same function under all of them. HD Sentinel doesn't monitor every SMART attribute that a drive reports, only those that are applicable to the type of drive. For example, with wear leveling in SSDs, every write is remapped to a different memory block, so how would the Total LBA Written tell you how many times a particular memory block got written to know how often it got stressed to reduce its longevity? More important for SSDs would be the Reallocated Sectors Count and Used Reserve Block Count. SSDs are overprovisioned to start with (and some tools lets you change by how much, like Samsung Magician). |

The executable is a Linux executable, with no EXE file extension. There are downloads for Windows, too, on that page and they do have .exe for an extension. So now I'm seeing at least five different pieces of software. Because the label said "Samsung Magician" and not "Samsung Magician DC" for the subsection, I mistook that for the "regular Magician". The regular Magician is what I already have in Windows 10 (because it works with my drives). Regular Magician == what I'd use for my consumer drives. Up around at least version 5 Samsung_Magician_DC_Windows_32bit.exe == "version 1" (???) Samsung_Magician_DC_Windows_64bit.exe == "version 1" (???) Samsung_Magician_DC_Linux_32bit.zip == "version 1" (???) Samsung_Magician_DC_Linux_64bit.zip == "version 1" (???) Samsung_SSD_DC_Toolkit_V1 == "version 1" (contains 32b and 64b Linux cmdline) There must be some functional overlap in the three Linux versions. The OP can test it. And as if that isn't enough, regular Magician is crap :-/ And that's why we'd need that many versions. The Corsair Neutron toolbox, did Secure Erase without wimpering. Click a button and done. All that Magician will do, is explain to you how the chipset is getting in its way and so on. It doesn't do anything if you need a Secure Erase. How did marketing decide Magician was the right name ? Why did the Corsair Neutron toolbox work ? (I tested both on the same machine.) I secure erased the Neutron before returning it for a refund (so I can no longer test it). Paul |

I've been in about 500 data centers over the past 10 years and I can say that Windows is alive and well there. Domain controllers are nearly everywhere, running a version of Windows Server, and MS Exchange is also extremely widespread. The web servers and other application servers run whatever the software vendor says they need to run. If I had to guess, I'd say that's about 65/35 Linux vs Windows. The interesting part is that 10 years ago, virtualization was a rare novelty. These days, I'm surprised when I *don't* see it being used. -- Char Jackson |

When I went to Magician 5.0, lots of settings disappeared, so only Samsung knows what their latest version will do for those settings. While I kept the old version's installer, I still moved to the new version (and now have 5.1) because I wanted the newer Rapid Mode driver. https://i.stack.imgur.com/cbeTr.png All those OS optimization settings disappeared in v5. Haven't bothered to figure out what their software does now. |
