My understanding is that disk drive use, and windows use of sector size are two different things. Install and launch the software. Further, if you send data down in “clumps” of 4096 bytes rather than 512 bytes then everything has less work to do for the same total I/O and the I/O will be more frequently aligned. # parted -l Model: HP SSD EX900 120GB (nvme) Disk /dev/nvme0n1: 120GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 962MB 960MB fat32 boot, esp 2 962MB 42. You've formatted & installed windows under 4k, however the physical drive (of most SSDs) uses 512 regardless. One of the options is sector size. I also tried to delete the default namespaces (nvme detach-ns + nvme delete-ns) and create a new namespace of 4k size (create-ns), but it failed. The physical sector size should be checked first during partitioning disk, for physical sector on some disk may contain 4, 8, 16 or more logical sectors (always 2 nth power). Chứng nhận từ phòng thí nghiệm, mọi ổ SSD WD . flashbench 6 7 results strongly suggest that the internal sector size is 8KB. The concept of Advance Format storage devices, with their underlying 4k sector sizes, is one which can cause a certain amount of confusion to newcomers. The command -nvmeformat also includes additional parameters that can configure different drive's settings such as Secure Erase, Protection Information, and Meta Data. A "B-Key" enables SATA or PCIe NVMe™ SSDs using up to 2 PCIe lanes, while an "M-Key" enables NVMe™ SSDs with the use of up to 4 PCIe lanes. page may show increased value at attributes #5 Reallocated sector count, #198 Off-Line Uncorrectable Sector Count or similar attributes. We can also create 4K sector size flash LUNs on the IBM .
