Crucial T700 marks the brand's return to the high-end SSD segment after years of catering to the mainstream segment with well-priced drives that the company can move in high volumes. The company had retired its Ballistix brand to mark its withdrawal from the high-end. The drive combines Micron's 232-layer 3D TLC NAND flash with a Phison E26-series controller and LPDDR4-based DRAM cache, and takes advantage of the PCI-Express 5.0 x4 host interface, with NVMe. A small section of the tech press was sampled with these drives and permitted to do performance previews.

Every SSD manufacturer's favorite benchmark, CrystalDiskMark (CDM), shows the drive clock 12.4 GB/s sequential reads (1 MB, QD8), along with 9.22 GB/s (1 MB QD1). Sequential writes are as high as 11.87 GB/s (1 MB QD8), and 9.66 GB/s (1 MB QD1). IOMeter testing revealed that the sustained write speeds are rather low, with the T700 holding onto top speeds only up to 25 GB, beyond which write performance falls off a cliff to 3.8 GB/s.
