“The SanDisk X400 is the flagship model of SanDisk’s business/OEM SSD lineup,” Billy Tallis writes for AnandTech. “As the successor to the X300 and X300s, the X400 continues the strategy of combining premium features like encryption and a 5-year warranty with the use of cheaper TLC NAND flash to hit mainstream price points.”
“Unlike most TLC product lines, the SanDisk X400 provides usable capacities at power of two increments: 128GB through 1024GB, rather than the more common 120GB through 960GB,” Tallis writes. “SanDisk hails the X400 line as including the first single-sided 1TB M.2 SSD.”
“In addition to raising the bar for planar TLC performance, the SanDisk X400 sets a new standard for power efficiency of drives using TLC NAND. It routinely ties or beats at least a few MLC SSDs for power efficiency, especially when its performance is not lagging far behind,” Tallis writes. “It is refreshing to see a TLC drive that provides progress on something other than price. The X400 is a credible mid-range SSD that achieves SanDisk’s goals and proves that even planar TLC NAND can compete for the mainstream segment.”

MacDailyNews Take: At $229.97 for a 1TB M.2 SSD, the SanDisk X400 is mighty tempting.
