The Crucial T700 Gen5 SSD is a solid-state drive designed in the M.2 2280 form factor, measuring 22mm wide and 80mm long. It employs the PCI-Express 5.0 x4 interface, providing double the theoretical bandwidth compared to its PCIe 4.0 x4 counterpart.

The T700 SSD's PCB hosts the Phison PS5026-E26 controller, Phison's flagship product and first PCI-Express 5.0 controller. It supports eight flash channels, NVMe 2.0, and is based on an Arm Cortex design, fabricated using a 12-nanometer process at TSMC Taiwan.

A thin metal heatsink distinguishes the T700 SSD from previous models. Removing the front brand sticker does not void the warranty, making it more friendly when mounted under a motherboard heatsink (which is a must). The design includes a double-sided particle layout and a three-layer structure with metal material in the middle. The back features a product label sticker displaying the model number, CT2000T700SSD3, and the PCIe Gen5 x4 M.2 2280 specification.

The T700 Gen5 SSD weighs approximately 9.2g with the thin heatsink and 8.1g without it. The cooler increases the weight to around 49.2g. Crucial's warranty is not affected by removing the metal thermal pads and stickers from the front panel.

Internally, the front side hosts a main controller chip, a power management IC, a DRAM chip, and two NAND flash chips. Removing the product label on the back may impact the warranty. The back side features two NAND flash chips and an empty DRAM SMT trace, which might be utilized in the 4TB version. The T700 employs the PHISON PS5026-E26 as the main controller, a departure from previous models that used Micron's main controller. The PMIC is the PHISON PS6125, while the DRAM chip is a Micron LPDDR4-4266 with a 4GB capacity. The NAND flash is Micron 3D TLC 232L NAND, with two chips on the front and two on the back.

One version of the T700 model comes with heat-dissipation protection by a heatsink, employing aluminium extrusion technology and featuring five layers of heat-dissipating fins.
