Kioxia's Exceria Plus G4 comes in a compact box with an image of the drive on the front, along with a sticker displaying the capacity of the drive and the drive's Sequential read speed (up to 10,000MB/s). The rear of the box has a description of the drive’s form factor, a small logo representing it uses BiCS Flash, PCIe 5.0 (NVMe 2.0c) interface and has a 5-year warranty.
The Exceria Plus G4 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.
The drive is built on a single-sided format, so all the components are on one side of the PCB. Alongside the Phison PS5031-E31T controller sit two 1TB packages of Kioxia BiCS8, 218-layer 3D TLC NAND.
The four-channel Phison PS5031-E31T is the company's second PCIe Gen 5 controller and holds a couple of world's firsts – first Gen5 controller for the mainstream market segment and the first DRAM-less Gen5 design. Built on a 7nm process, the E31T uses HMB technology instead of a dedicated DRAM chip. It supports four NAND channels with data transfer speeds of up to 3600 MT/s. Data reliability is provided by Phison's 7th generation LDPC ECC along with End-To-End Data Path Protection and Smart ECC 2.0. It also supports AES 256-bit Encryption.
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.
