Thanks for your interest in our products.
One of the differences between Intel® Optane™ SSDs (which implement 3D XPoint™ instead of NAND technology) is that overprovisioning is not strictly required in order to maintain high random performance and consistency. Please bear in mind that most drives come with overproviosioning by default, even though it is not visible to the end user in most cases. It is up to the users and their needs to add a custom value if required.
However, it is important to notice that Intel® Optane™ SSD 900p and 800p Series are part of the Intel SSD Enthusiasts and Consumer families, this drives are not intended to be used on data center or server environments. For that, we recommend the Intel SSD Data Center Family.
Please let us know if there's anything else we can do for you.
