The Solidigm D5-P5336 is a solid-state drive in the U.2 form factor, launched on July 24th, 2023. It is available in capacities ranging from 7.5 TB to 61 TB. This page reports specifications for the 61 TB variant. With the rest of the system, the Solidigm D5-P5336 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the SLNQG (Sentinel Rock Plus) from Intel-Broadcom, a DRAM cache chip is available. Solidigm has installed 192-layer pQLC (PLC) NAND flash on the D5-P5336, the flash chips are made by Intel. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The D5-P5336 is rated for sequential read speeds of up to 7,000 MB/s and 3,300 MB/s write.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Solidigm guarantees an endurance rating of 65200 TBW, a good value.

Notes

NAND Die:

Die read speed: aproximation
Die write speed: aproximation
In order to enable a balanced Gray data encoding, all five pages of data are needed in
both the first and second pass of the program algorithm. While this is the norm for most
QLC implementations except [1], it requires the storage of a few megabytes of data per
die in a DRAM or similar media. Instead, we use a 1b/cell (SLC) cache on the NAND die
to store the data needed for the two-pass PLC programming algorithm. To keep the area
overhead of the SLC cache to less than 2%, we improved the SLC reliability to 250k
program/erase (P/E) cycles, commensurate with 1k of P/E cycle capability in the present
PLC work.
