Kioxia's Exceria PRO 4TB comes in a compact box with the drive image on the front and a sticker displaying its capacity and sequential read speed (up to 14,900MB/s).
The rear of the box includes a description of the drive’s form factor, a small logo indicating it uses BiCS Flash, a PCIe 5.0 (NVMe 2.0d) interface, and a 5-year warranty.
The Exceria PRO G2 is built on a single-sided M.2 2280 format. The product label on the front of the drive incorporates what looks like a copper strip to help get rid of some of the heat generated by the drive.
As the drive is a single-sided format, all the components are on one side of the PCB. Alongside the Silicon Motion SM2508 controller sit two 2TB packages of Kioxia BiCS8, 218-layer 3D TLC NAND and a DRAM IC (SK Hynix H9HCNNNCPUML).
Silicon Motion's SM2508 is an 8-channel controller built on a 6nm process that offers a balance between high performance and low power usage. It uses a quad-core 32-bit Arm Cortex-R8 processor running at 1.25GHz in conjunction with a single 32-bit Cortex-M0. The eight NAND channels support 3D TLC/QLC NAND technologies at speeds of up to 3,600 MT/s.
Kioxia's SSD Utility drive management software has four main sections: Disk Information, System, Settings and Help. All the key tools are to be found on the Disk Information page under separate tabs. These allow you to check drive capacity usage, health and temperature, SMART information, drive alerts and perform operations such as firmware updates and secure erase.
