Solidigm D5-P5336 vs KIOXIA LC9
Solidigm D5-P5336 is an established PCIe 4.0 QLC family up to 122.88TB. KIOXIA LC9 is a PCIe 5.0 high-capacity QLC family that extends to 245.76TB and publishes multiple logical-block and security options.
Their endurance figures are not directly comparable without the LC9 indirection-unit format and exact capacity.

Interface and platform differences
LC9 uses PCIe 5.0 and NVMe 2.0, while P5336 uses PCIe 4.0 and NVMe 2.0. Gen5 raises the link ceiling, but application performance still depends on controller behavior, queueing, software and shared PCIe topology.
KIOXIA lists single- and dual-port options plus security variants. Match the exact ordering option because those capabilities should not be assumed for every LC9 unit.
Capacity and density
P5336 begins at 7.68TB and reaches 122.88TB. LC9 begins at 30.72TB and reaches 245.76TB, with the largest capacity in E3.L.
LC9 can halve device count at the very top end, but availability, chassis qualification, spare strategy and failure-domain concentration can outweigh raw density.
Endurance requires careful normalization
KIOXIA publishes different LC9 DWPD figures according to indirection-unit format, including 4KiB and 16KiB cases. P5336 publishes capacity-specific five-year DWPD and PBW figures.
Compare the exact format used by the application and array. A headline endurance comparison that ignores block format can be materially misleading.
Frequently asked questions
Which has the larger maximum capacity?
KIOXIA LC9 reaches 245.76TB; Solidigm D5-P5336 reaches 122.88TB.
Why does LC9 list more than one DWPD figure?
Its published endurance depends on the selected indirection-unit format, so 4KiB and 16KiB configurations should not be treated as the same endurance case.
Which is broadly better?
Neither is universally better. Platform qualification, capacity target, form factor, endurance format, availability and support determine the correct purchase.
