Hi, I recently bought a 8TB Drive, "SSDPE2KX080T851".
I saw that this was once a $5K enterprise drive, and comes with many high performance quality of service claims made as part of its marketing documents.
However, the drives full stats and capabilities seem to be very scarce. I've been looking for info on what the size of the drives DRAM cache is (I don’t think any business class drive that cost as much as this did in recent times would not have one), but it doesn't appear anywhere. There is an older article that states it's 1GB per TB, but the model numbers don't exactly match since this article was written some years ago (here: https://www.tweaktown.com/reviews/8618/intel-dc-p4510-2tb-8tb-enterprise-pcie-nvme-ssd-review/index...., and here https://www.anandtech.com/show/13704/enterprise-ssd-roundup-intel-samsung-memblaze/3)
The claims made in the drives documentation state that it contains "enhanced QOS capabilities", "firmware enhancements with new 3D NAND features to prioritize host workload and ensure better service levels", and other claims related to its internal controllers and caching abilities that allow it to provide reliable performance across all queue depths and random operations, “that keeps host and background data read/write at an optimum balance” and provide "End-to-end data protection", and "power loss imminent (PLI) protection"… which would be impossible without caching. However, none of these are exposed by the driver to a Windows host OS or through Solidigms software, and Windows will not allow write caching on it as a result. HWInfo64 states that this drive has fewer capabilities than an average consumer drive, which also seems to be a result of the lack of management and reporting interfaces available to any current Windows software I can find. In total, if all these capabilities are locked away from the user for reasons related to it being a data center device, does the remainder of the documentation of it's hardware exist somewhere? Will these be added back in future drivers?
