Final Thoughts and Conclusion
Silicon Power’s UD70 M.2 drive provides a high-performance storage solution for a budget price. With a street price of about $190, the 2TB model of the UD70 is one of the cheapest 2TB M.2 drives out there but delivers the performance of drives costing 50% more. QLC memory does incur a performance penalty if you write to the drive continuously long enough to saturate the cache, but most users won’t be able to do this with typical desktop use.
As Silicon Power touts good thermal control of the UD70, we left the motherboard heatsink off the drive and tested it as is. We hit a maximum temperature of 67C under sustained stress testing which did not cause the drive to throttle. With most desktop motherboards now providing at least one heatsinked M.2 slot, this isn’t terribly important for most desktop users. For those of you who intend to use the UD70 in a laptop or small form-factor build, this is a very good thing and something that many M.2 drives struggle with.
If you are looking for your next storage upgrade, look no further. The price to performance to capacity ratio of the UD70 is unmatched!
Great job Silicon Power!
