Those values match the SanDisk Portable SSD (E30) with the G26 model numbers. The article also says the starting price is 100 US dollars and names no controller, flash or write speed

SuccessoriThe model that directly replaced this one, in the same line, tier and size. A revision such as a Slim or OLED model does not count when a next generation exists.
