SanDisk is the world's largest supplier of data memory card products. In October 2015, SanDisk was acquired by Western Digital, which leveraged SanDisk's core technology to enter the SSD market. In 2016, SanDisk had a market share of 13.6%, ranking second in the world. SanDisk shares flash memory technology with Toshiba, and SanDisk's new SSDs feature Toshiba's latest Bics 3D flash memory.
 
SanDisk "resurrected" the old high-end product line in 2018 - SanDisk Extreme PRO SSD, like memory cards, the Extreme PRO and Extreme PRO series represent SanDisk's flagship and entry-level products, respectively, but SanDisk has not many products on sale, and they are all TLC flash memory particles, consumers with high demand for hard drive durability need to pay attention.
 
As a new flagship product in 2018, SanDisk Extreme PRO has excellent performance, with slightly better read and write speed data than the Samsung 970EVO in the same class, and provides a 10-year ultra-long warranty, which is the longest warranty period among consumer SSDs, reflecting the reliability of the product from the side.
 
SanDisk's entry-level SATA SSD Extreme 3D performance is slightly weaker than the Samsung 860EVO and Critical MX500, and the price is higher than that of Samsung and Critical at a lower price. However, the Extreme 3D comes with a 5-year warranty, which is better than the 3-year warranty of the Critical MX500.
