Silicon Power XPower XS70 SSD Review: Fast, Attractive, and Affordable

Silicon Power’s XS70, also known as the XPower XS70, is rated up to 7.3 GBps of bandwidth, which is effectively the limit of consumer PCIe 4.0 SSDs. This drive is capable of up to 1 million IOPS, which matches expectations, and comes with a five-year warranty. Silicon Power markets the XS70 as a gaming drive, with specific attention given to the attractive aluminum heatsink. 

Silicon Power is another third-party SSD manufacturer that also makes other products, predominantly flash-based drives that vie for a spot on our list of Best SSDs. The company’s most popular SSDs are and were the P34A60 for budget or entry-level, and the perennial mainstream P34A80. The latter was one of the first SSDs based on the Phison E12 controller and it maintained the original hardware layout for a significant period of time. Eventually, it transitioned to using the Phison E12S or Silicon Motion’s SM2262EN controller. Such swaps are common in the industry, but this made the drive less desirable.
