Kioxia CD8P-R 30.72TB Performance by CPU Architecture
Now that we are firmly in the PCIe Gen5 era, we have a number of AMD, Intel, and even AmpereOne platforms to test the drives in to see the differences in performance based on architecture. These are small, but important.
Since that is hard to read, we have a zoomed-in view below without a 0 X-axis.
We see a similar trend to the previous PCIe Gen4 generation, but AMD has actually done a lot to close the gap in terms of PCIe performance here and Kioxia is doing better than some others on the AMD CPUs.
It is fun to see that not all PCIe controllers are created equally and that there are differences even based on the platform the drive is put into.
Final Words
In 2025, we have already had the Kioxia LC9 122.88TB PCIe Gen5 NVMe SSD announcement. If you are solely looking for capacity, then there are currently two tiers of capacity above this one at the 61.44TB and 122.88TB sizes. At the same time, outside of large AI clusters 15.36TB and 30.72TB SSDs are becoming more popular. The Kioxia CD8P-R is not designed to be the highest capacity drive, but instead as a balance point between performance, capacity, and price.
While these may not be the fastest drives out there, the Kioxia CD8P-R 30.72TB NVMe SSDs offer a lot more density and performance than hard drives.
I did not see the $/TB cost nor an estimate on expected power-off data retention.
In addition to @Eric’s comment I’d like to see latency (with charts like StorageReview does).
If all the info could be presented in a chart like @Patrick’s excellent CPU comparison charts (such as the style of “AMD EPYC 9004 Genoa SKU List And Value Analysis Comparison To Milan And Rome By Core Count”), but for SSDs instead of CPUs that would be a valuable addition.

I saw neither cost nor price, so the last sentence does not make sense.
For those asking about the cost per TB, data retention lifetime and latency, here is what I could find from a very quick search:
Unit price: $4,799.00 at Newegg.com for model number KCD8XPUG30T7 (This will likely be the same or close to the same for other vendors.)
$/TB: $156.22
Latency and data retention are not given. This would be a datasheet item and this isn’t given in any of Kioxia’s documentation. Kind of a fail on their part.
What i know, Data-Retention is always the same. No real details, only JEDEC standards: 3 months at 40°C in power-off state by assuming that the SSD reaches the maximum rated endurance.
Never saw something different. probably this is a point, why the pro/consumer SSD’s have less endurance. They have to retain the data much longer. I am not even sure if there is a real binning of NAND dies for enterprise SSD’s.
