Silicon Power UD90 Spec and Price in Italy
Released May 20, 2022
Silicon Power builds the UD90 without a DRAM cache, relying on Phison's E21 controller and TLC NAND to still reach 5000/4800 MB/s over PCIe 4.0 — slower than DRAM-equipped Gen4 drives but well ahead of any SATA option. Its 1200TB TBW rating and 5-year warranty are unusually generous for a DRAM-less design, suggesting a mainstream rather than bargain-bin positioning. It suits users wanting NVMe speed gains over SATA without paying for a DRAM cache they may not need for typical desktop use.
Tied 48th of 106 models in the SSD catalog on Sequential read — 8 models share this figure. Tied 46th of 106 models in the SSD catalog on Sequential write — 2 models share this figure.
