The US70 PCIe Gen4x4 drive from Silicon Power does trade punches with the products we have tested before from the same category and in many cases, it did succeed to stay on top! The 2TB version of the product comes with a 3600TB rating and 5 years warranty, so you do not have to worry about endurance even when performing storage intensive activities. US70 thanks to its firmware and controller does make use of technologies such as LDPC, TRIM, SLC caching, DRAM cache buffer, End-to-End Data protection in order to keep a high sustained write data rate for longer and also has wear leveling in order to have a similar usage throughout all internal cells.

By using HD Tune Pro write test, we can see how the drive behaves when SLC cache has been filled; we can see a quite abrupt drop, but the drive can recover fast and will continue to write at high speeds:

The Silicon Power US70 drive can be found online for about 343 Euros, the most affordable 2TB version in PCIe Gen4x4 format, so it should be on your shortlist when building a computer or upgrading one with existing PCIe Gen4 support.
