S2D 4k vs 64k which one should i choose?

Copper Contributor

Have read on numerous blogs a potential performance impact when using 4k block size for volumes in S2D vs 64k.  What does microsoft recommend for optimal performance?

Good question. S2D will work with either, but storage spaces is optimized for 4k. It does many operations on a block basis and in 4k chunks so if they are 64k blocks it just means reading in and writing more data than necessary.
Yes, thank you for the quick answer.
