NAND flash technology has seen rapid advancement in recent years. This has resulted in the capacity limits of SSDs and thumb drives getting pushed up regularly. Companies like Kingston had innovated in the late 2010s to deliver 1TB and 2TB thumb drives. They were overpriced and over-sized for their product class at that time. However, interest in this category has been sparked again by the introduction of high-performance native UFD controllers and the appearance of cost-effective high capacity NAND dies. Silicon Power and Transcend recently released 2TB thumb drives based on the Phison U17 and Silicon Motion SM2320 native UFD controllers respectively. Read on for a comprehensive analysis of the performance profile and value proposition of the Silicon Power MS70 in its 2TB avatar.
