Solidigm D7-PS1010 and D7-PS1030: PCIe 5.0 and 176L TLC Datacenter SSD Performance Play
by Ganesh T S on August 6, 2024 11:00 AM EST 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.
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 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 claims better energy efficiency compared to the competitors' Gen 5 drives from last year for various AI workload traces.
