INTRODUCTION

   PCIe 5.0 Gen5 M.2 NVMe solid state drives (SSDs) may have finally hit 14.000MB/s in reads and writes (not sustained obviously) but be it due to system compatibility, cost or needs for the vast majority of people PCIe 4.0 Gen4 models still represent the best price/performance ratio. Because of that it's no surprise that pretty much all semiconductor and storage media manufacturers are focused in the design and release of Gen4 NAND flash controllers and drives respectively. Silicon Power somewhat recently updated their PCIe 4.0 Gen4 M.2 NVMe SSD lines to include their latest US75 model and today I’ll be testing the 2TB capacity variant.

   Founded in 2003 by a group of enthusiastic data storage industry experts, Silicon Power is committed to delivering outstanding product and service quality. Headquartered and with our own state-of-the-art production site in Taipei, we have become a leading manufacturer of flash memory cards, USB flash drives, portable hard drives, solid state drives, DRAM modules and industrial-grade products. As an international player with four branch offices around the globe, we continuously strive to offer the perfect data storage solution for all requirements of modern digitalized life. With a strong focus on combining innovative technology and award-winning design, we live up to our brand promise to reliably preserve and protect your most valuable data. Because memory is personal.

   The US75 line of PCIe 4.0 Gen4 M.2 NVMe SSDs by Silicon Power is currently available in 500GB/1TB/2TB/4TB capacities and is actually the 6th model to arrive in the lab featuring MaXio's DRAM-less MAP1602 12nm quad-channel (R5) NAND flash controller which this time over is paired with YMTC's very first 232-layer 3D TLC NAND flash. Again, the MAP1602 12nm quad-channel NAND controller by MaXio packs quite a few technologies including advanced wear leveling algorithms, Host Memory Buffer (HMB) architecture (uses a fraction of your PC's system memory to cache mapping tables), pseudo SLC cache, bad block management strategy, hardware error-correction, L1.2 ultra-low power state and sudden power-loss protection, TRIM, NCQ, hardware support for AES256/SM4 encryption and support for TCG OPAL2.0. Silicon Power covers their entire US75 line with a 5-year limited warranty and reports an MTBF of 1.5 million hours for all variants and a TBW (terabytes written) of 300 for the 500GB model, 600 for the 1TB model, 1200 for the 2TB model and 2400 for the 4TB model.
