Princeton Expands Mainstream PCIe 4.0 SSD Line With DRAMless TLC Models

Princeton Memory unveiled the PHD-ISM2G4DG in 512 GB, 1 TB, and 2 TB capacities. The drives use a Phison E27T-series DRAMless controller paired with 3D TLC NAND flash, with quoted sequential read speeds up to 7,100 MB/s and write speeds ranging from 4,300 MB/s on the 512 GB model to 6,400 MB/s on the larger versions. Endurance is listed at 160 TBW, 320 TBW, and 640 TBW respectively, and the lineup carries a three-year warranty. For the broader memory market, the announcement is more relevant as a demand and product-positioning signal than as a direct pricing catalyst. It points to continued use of TLC NAND in mainstream PCIe 4.0 storage, but the source does not indicate shipment scale, supply changes, or procurement activity large enough to shift NAND pricing on its own.
