I found out that some applications like VMware VSphere 6.5 and VMware vSAN 6.5 6.6 don't support drives with 4K sectors:

However some SSDs like the Intel P4800X (Optane) and S3500/S3700 can be converted to 512 byte sectors:

While this spec sheet for Crucial MX300 has 512 byte sector size support as one of the features.
Samsung 840 Pro spec sheet:
https://www.samsung.com/us/pdf/memory-storage/840PRO_25_SATA_III_Spec.pdf (page 7)
Any other SSDs with 512 byte sectors or capable of 512 byte sectors?

Do current GA versions of vSphere and VSAN support 4K Native drives?
No. 4K Native drives are not supported in current GA releases of vSphere and vSAN.

Any other SSDs with 512 byte sectors or capable of 512 byte sectors?
