The UD70 mainstream SSD from Silicon Power is QLC-based but also uses DRAM caching and a Phison PS5012-E12S-32 controller, succeeding to keep writing speeds over 100MB/s after the SLC pseudo-cache has been fully occupied. With the SLC cache emptied, it can reach the rated speeds without any issues at all, making it an ideal upgrade for mainstream desktops/laptops which need a performance jump from regular 2.5’’ SSDs.

By using the HD Tune Pro write tests, we can check out the drive behavior after the SLC cache has been fully filled up:

This drive is kept cool with additional functions at the firmware level such as active state power management or the autonomous power state transition, which not only allows the unit to function in computers with less than ideal airflow (such as laptops) but also maximizes its lifespan.

The UD70 drive can be found in 500GB, 1TB and 2TB flavors; the 1TB model can be picked up for about 120 Euros (at the time of the review).
