Silicon Power UD90 1TB M.2 NVMe SSD Review

Recently, Silicon Power has been releasing a series of fast and high performance SSDs for desktop computers, but not all users need the top series SSD to see a smooth daily performance. We had a chance to review the top-performance XS70 some weeks ago, and now is the time to present the latest SSD which is simply called UD90. The new SSD is rated at lower sequential bandwidth of 4800MB/s, but still promises high performance and optimal results in random operations. There are more features worth mentioning but I won’t share everything in the introduction, so you have to check the whole review to find out how much the UD90 SSD has to offer.

Let’s start with specifications and features, and later, we will test the performance of the 1TB version of the UD90 M.2 SSD on one of the fastest motherboards with the Z590 chipset.
