Silicon Power UD90 Spec and Price in France

NVME2TBM.2 22805000 MB/s read

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.

How to choose an SSDFour questions decide almost every SSD purchase — what fits, how big, how fast, and how much it should cost.NVMe or SATAWhich interface your machine takes, how to tell without opening it, and what the speed difference actually buys you.How much SSD capacity you actually needHow to size a drive from what you already use, why leaving headroom matters, and when one bigger drive beats two small ones.M.2 sizes and SSD form factorsWhat 2280, 2242, and 2.5-inch mean, which one your machine takes, and how to check the keying before you buy.What SSD speed numbers actually tell youSequential versus random performance, why the number on the box describes the rarer case, and how to read it without being misled.PCIe generations for SSDsWhat Gen 3, Gen 4, and Gen 5 change, why a newer drive always works in an older slot, and when the extra speed is worth paying for.TLC, QLC, and DRAM-less SSDsWhat the NAND type and the controller's cache change about how a drive behaves, and when either is worth caring about.SSD endurance and warrantiesWhat TBW and DWPD actually promise, how much a normal machine writes, and when endurance is worth paying extra for.How to install an SSDFitting an M.2 or 2.5-inch drive, choosing between cloning and a clean install, and what to check on the first boot.When an SSD price is actually goodWhy price per terabyte beats any discount percentage, and why a good price on one capacity says nothing about the others.

What owners and reviewers say

Summarised from 1 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • Great performance results at an affordable price, with no thermal throttling and good sustained writes.
  • Outstanding synthetic results, under a five-year warranty in a compact form factor.

Commonly criticised

  • Slower and more expensive than some competing drives.
  • A small cache and a DRAM-less design.
