The UD90 is available in capacities up to 1TB. I wish it was some more as the current SSD prices cause that 2TB is already more interesting for many users. Of course, there are other Silicon Power SSD available up to 4TB, but can be less wallet-friendly than the UD90. The price is actually a strong point of all Silicon Power SSD. Typically, we can expect about the same performance as in the competition but at about a 10% lower price. It of course depends on the specific SSD model.
The SSD has no heatsink and it heats up less than the top SSD series like the previously reviewed XS70. The temperature during standard work on an MSI Z590I Unify with its heatsink was about 45°C. We haven’t registered more than 52°C. The motherboard is equipped with a heatsink but the OS drive is on the other side of the PCB so raises the temperatures around. Considering all the ambient temperatures, the UD90 still runs cooler than most other PCIe 4.0 x4 SSDs on the market. It makes it a great option for mobile computers that lack space and airflow.
The throttling point is set at 70°C which is pretty common in most NVMe SSD. It’s still much higher than the typical temperature of the UD90 SSD.
Below is a screenshot from the CrystalDiskInfo, which shows that the SSD is in perfect condition.
Let’s move to the next page to take a closer look at the package and the drive itself.
