The 1TB SanDisk Ultra 3D SSD is the first SanDisk solid state drive to feature their 64-layer 3D NAND technology that delivers higher storage capacities, performance and endurance, with lower power consumption. Let’s see if the 1TB SanDisk Ultra 3D SSD delivers on that promise!
The SanDisk Ultra 3D SSD Family
The SanDisk Ultra 3D SSD family consists of four models built upon the same technology. They mainly differ in storage capacities, with some performance characteristics. Here’s a table comparing their key specifications :

The 1TB SanDisk Ultra 3D SSD Up Close!
The 1TB SanDisk Ultra 3D SSD (Price Check) comes in a deceptively light cardboard box. Let’s unbox it and take a closer look!
The 1TB SanDisk Ultra 3D SSD (Price Check) is a low-profile 2.5″ drive, with a thickness of only 7 mm. This is thinner than the regular 9.5 mm drives, making it suitable for all 2.5″ drive bays, even in thin laptops.
