How do I check my SSD sector size?
This answer is severely outdated.
- Run msinfo32 in command line that should popup a GUI window called “System Information”
- In the left pane select “System Summary->Components->Storage->Disks”. This should load info of all drives in the right pane.

What is drive sector size?
In computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disc. Each sector stores a fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs) and 2048 bytes for CD-ROMs and DVD-ROMs. The sector is the minimum storage unit of a hard drive.
What is the best NTFS allocation unit size?
4096 bytes
If you are a “Standard User” by Microsoft’s definition, you should keep the default 4096 bytes. Basically, the allocation unit size is the block size on your hard drive when it formats NTFS. If you have lots of small files, then it’s a good idea to keep the allocation size small so your harddrive space won’t be wasted.
How do I change the physical sector size of my SSD?
Enter the command to change the wanted Physical Sector Size:
- To change Physical Sector Size to 4K type isdct.exe set -intelssd X physicalsectorsize=4096.
- To change Physical Sector Size to 512 (512e), type isdct.exe set -intelssd X physicalsectorsize=512.
What is the largest size of a hard disk sector?
512 bytes
Usually, one sector of a hard disk drive or floppy disk can hold 512 bytes of information. This standard was established in 1956. In the 1970s, larger sizes such as 1024 and 2048 bytes were introduced to accommodate larger storage capacities. One sector of an optical disc can usually hold 2048 bytes.
What is the physical sector size of the Intel® solid state drives?
These Intel® Solid State Drives support a 512 byte and 4096 byte (4K) physical sector size. Most operating systems provide optimal system performance when using the larger physical sector size.
What is the size of a solid state drive (SSD)?
These Intel® Solid State Drives support a 512 byte and 4096 byte (4K) physical sector size. Most operating systems provide optimal system performance when using the larger physical sector size. The following firmware releases set the default to 4K, which is a change from the default setting of previous firmware versions.
Instructions for changing the physical sector size. If your Intel Solid State Drives are set at the 512 byte physical sector size, you can change them to 4K. To change the physical sector size, follow these steps: Go to the Download Center, click your operating system, and download and install the Intel® Solid-State Drive Data Center Tool.
What is the actual sector size of an Advanced Format Drive?
Given that i have an Advanced Format drive (i.e. it uses 4,096 bytes per sector rather than 512): can report the underlying physical sector size. It makes sense when you realize they both report the sector size that Windows is using.
