Re: NVMe sector size ?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Almost all NVMe drives use 4k sectors.  Its actually hard on the drive to use 512 byte sectors, as when you write a block and sync it, it has to read and then rewrite the rest of the 4k block.  That's unnecessary writes, shortening your drive life.  Most Linux platforms will read the natural sector size from the drive when you format it, so using 512 byte sectors is pretty rare these days, unless you forced it of course.

Hi guys.

I wonder if anybody played with both sector sizes 512 & 4086 and if yes so - also had some test results / thoughts to share?

There are bits about it - bit confusing & a mixed-bag -  over the net but I failed to find anything Fedora-specific.

thanks, L.
