Solidigm's datacenter SSD lineup includes models targeting different
performance, endurance, and cost tradeoffs. Last year, the company had
introduced the D5-P5336 QLC drive as a low-cost high-capacity drive for read-
heavy workloads, while also preparing the SLC-based D7-P5810 for extremely
write-intensive workloads requiring high endurance. The D7-P5520 / D7-P5620
Gen 4 drives with Solidigm's own 144L 3D TLC have been the high-performance
offerings for generic workloads over the last couple of years.

Solidigm is announcing the availability of the successor to the D7-P5x20
today - the new D7-PS1010 and D7-PS1030. Both of these NVMe drives use SK
hynix's 176L 3D TLC NAND and come with a PCIe 5.0 interface. The third digit
in the model number matches the DWPD rating, with the D7-PS1010 targeting
mixed workloads with a 1 DWPD rating, and the D7-PS1030 targeting write-
intensive use-cases with a 3 DWPD rating.

Compared to the previous generation D7-P5x20, the D7-PS10x0 series brings
about the following upgrades:

Move from PCIe 4.0 x4 to PCIe 5.0 x4 Move from 144L floating gate 3D TLC
(Solidigm) to 176L charge trap 3D TLC (SK hynix) 25% longer mean-time between
failures (MTBF) at 2.5M hours 10x higher uncorrectable bit-error rate (UBER)
at 1E-18 1.8x to 2.8x improvement in high queue-depth random access IOPS 2.0x
to 2.2x improvement in high queue-depth sequential access throughput

The specifications of the two new SSD families are summarized in the table
below.

Based on Solidigm's own internal testing, the D7-PS1010 compares very
favorably against the Gen 5 datacenter SSDs already in the market from
Samsung and Kioxia. However, the recently introduced Micron 9550 series may
present a better challenge to Solidigm's claims.

Gen 5 SSDs are well-suited for the storage-intensive tasks in AI workloads.
Every new product needs to tie itself to the AI buzzword currently, but we
should excuse SSD manufacturers for doing the same - after all training and
inference needs to move large amounts of data back and forth between the
processing engine and underlying memory. Solidigm expects the D7-PS10x0 to be
a good fit as direct-attached storage internal to GPU servers or as all-flash
tier supporting a HDD-only object tier in the cloud. For on-premises GPU
servers, the flash / HDD tiered storage can be replaced by an all-QLC object
tier.

Solidigm claims better energy efficiency compared to the competitors' Gen 5
drives from last year for various AI workload traces. While the data ingest
and archival processes require system designers to maximize the storage
capacity per watt (the QLC-based Solidigm D5-P5336 is attractive here), the
core processing steps require the optimization of performance per watt. The
D7-PS10x0 have a natural fit in this segment.

Solidigm / Intel has been serving the datacenter SSD market since its
inception. The company is well aware of the quality and reliability
requirements in this space. The D7-PS1010 and D7-PS1030 include the usual
enhanced PLI (power loss imminent) validation checks for data saved in the
process of power loss / restoration. The critical SRAMs in the SSD controller
also have ECC protection. UBER testing goes well beyond the suggested JEDEC
specifications. The company also claims that its silent data corruption
testing and modeling are better than its competitors.

The new D7-PS1010 and D7-PS1030 bring class-leading Gen 5 performance to the
datacenter SSD market. They are available for purchase now in both U.2 and
E3.S form factors, with capacities ranging from 1.6 TB - 12.8 TB (D7-PS1030)
and 1.92 TB - 15.36 TB (D7-PS1010).
