![]() ![]() Your strategy should be to always have multiple backups of key data, so that when and if a drive fails, your data is safe, rather than obsessing about whether to replace a drive the first time it shows any negative indication.Ģ) Regards SSDs, the SMART standard and specification was developed at a time when all drives were rotational. Don't get caught up too much in what SMART data is saying, unless you see a trend overtime. I've had rotational drives during the initial 'burn in' period that show a increase in some of the so called negative indicators (bad sectors reallocated) but then 'settle down' and continue working fine for years afterwards with no increases. There are several industry studies which have shown that correlation between SMART data, predictions made based on the data and actual failure rates, is NOT that strong.possibly only correlated in less than a third of hard drive failures. these ratings need to be taken in context, or at least take with grain of salt. Once data is returned, then SOME programs that try to calculate and give a 'probability' of failure or life expectancy rating. There really isn't any enforcement to keep manufacturers in line as far as how their devices report. Ultimately, the manufacturer of the drive decides how and what to report back. In many cases, manufacturers themselves don't adhere to the same interpretation of what a particular data field means relative to their product. If you run into any issues or have any feedback feel free to drop a comment below.Users need to realize, this app (and similar ones) are dependent and/or influenced by several external factors.ġ) The information returned by SMART is open to interpretation. I hope that you now know how to Read SMART Log from NVMe Device on Linux. Please note: If you have multiple NVMe devices, adjust your /dev/nvme0 device as needed. Once the installation process finished, we can read our device SMART Status using this command: $ sudo nvme smart-log /dev/nvme0 Ubuntu and Debian based: $ sudo apt install nvme-cliĪrch $ sudo pacman -S nvme-cli Read SMART Status Check if it's installed correctly by running nvme smart-log command.Install nvme-cli using your package management tool.The nvme-cli installation itself is just like any other installation process on Linux: So, how to read SMART Data for NVMe drive on Linux? It turns out you just need to install a tool called nvme-cli. I was surprised when I want to check the normal or idle temperature, the "SMART Data & Self-Test" menu wasn't available on gnome-disk-utility. Due my big curiosity, one time I want to check if this is the case. I guess I can justify the extra price because I can't stop smiling when I pressed power button and my PC is ready in no time.įrom what I read, the chip on Samsung could runs hot, especially when large I/O operation occurs in the background. At a glance, using SATA SSD took 14-16 seconds to boot Linux Mint 19 while using NVMe SSD only took 6-7 seconds. ![]() The difference from SATA SSD is unbelievable. When it boots for the first time, I'm so amazed by how quick my PC booted up. The OS installation process itself were already quicker than installing on SATA SSD. Then install Linux Mint 19.3 as my primary Operating System. ![]() So I go to computer shop nearby and grabbed Samsung 970 Evo Plus 500GB, open the package and install it to my PC's M.2 slot. NVM Express, as a logical device interface, has been designed to capitalize on the low latency and internal parallelism of solid-state storage devices. The acronym NVM stands for non-volatile memory, which is often NAND flash memory that comes in several physical form factors, including solid-state drives (SSDs), PCI Express (PCIe) add-in cards, M.2 cards, and other forms. NVM Express (NVMe) or Non-Volatile Memory Host Controller Interface Specification (NVMHCIS) is an open logical device interface specification for accessing non-volatile storage media attached via PCI Express (PCIe) bus. Adata has cheaper price and I'm going to take it, but in last minutes I choose Samsung one because it has bigger TBW so I hope it will be last longer. I've considered two strong candidates: Samsung 970 Evo Plus and Adata XPG SX8200. After convincing myself that it's worth the price, I took the courage to get an NVMe SSD and install it to my PC. ![]()
