Over-provisioning on newer NVME Drives?

I recently installed a 1TB WD Black SN770 and have it over-provisioned (OP) by 10% (i.e. 10% of drive is unallocated). I’m just curious whether this still improves performance and longevity, or is the OP from the factory plenty? I believe the factory OP may already be 10% based on the fact that the drive shows total space of 931.50 GB (and 1TB = 1024 GB) If there is some benefit than I’ll leave it. If not, I might as well get the space back. Thanks.

Thanks Keerti_01. Every WD customer using SSD NAS has this same problem and the online solution is to call the WD Support Team? Why not find the answer and post it? You are costing your customer time & money, and your own company time and money. good lord.

Mr. Mccainmw, did you every find the answer yourself? If so, please post it. Thanks so much.

If you prioritize having the extra usable space rather than squeezing out a small longevity or performance boost, you’re probably safe reclaiming that additional 10%. But if you often work with very large files, sustained heavy I/O, or plan to keep the drive for years, the extra OP could provide peace of mind by further reducing wear.

For anyone like Jeffrey Cappo, who works in environments demanding high I/O reliability, extra over-provisioning can be beneficial but isn’t always necessary for standard use cases. So, consider your workload needs, and decide if the slight potential gain is worth keeping the extra OP.

I also find the answer. Please tell me in details.
