The Elite A1 256GB card from Silicon Power does offer a notable improvement in terms of writes versus the non-A1 variant we have tested before, while offering the same levels of protection against water, dust, high-temperatures, and X-rays.

Test Setup and Test Results

The testbench was composed from the following hardware:

CPU: Intel Core i7-13700K

CPU Cooler: be quiet! Silent Loop 2 360mm AIO

RAM: Sabrent Rocket 32GB (2x16GB) 4800MHz DDR5

Video: PowerColor Radeon 5700 8GB

Power Supply: Cooler Master 850W

SSD: Sabrent Rocket Q4 NVMe PCIe 4.0 M.2 2280 2TB

Case: Cooler Master ATCS 840
