Another mainstream SSD from KIOXIA has arrived to our labs, carrying the EXCERIA PLUS G3 name. It comes with BiCS FLASH, supports PCIe Gen4 bus and was built on a 2280 form factor. The manufacturer has rated the drive with a maximum sequential read of 5000MB/s and write of 3900MB/s, and regarding capacity the product is available with 1TB and 2TB.

The drive is shipped inside a compact cardboard enclosure with the usual KIOXIA box art, showing the SSD in the frontal area, together with the drive capacity and the maximum rated sequential speed:

On the back, we will note the drive internal serial number, the manufacturing date, but also some product highlights:

The drive is held secure inside via a cardboard enclosure, but it is also additionally wrapped inside a transparent plastic film:

We will also receive some Safety Instruction documents, along with a short Installation Guide:

The drive is covered almost entirely by a sticker on the frontal area of the PCB; the sticker does also warn us that the surface is really hot and we should not touch it by mistake:

On the back, we will note that there are no other components available, but only a smaller sticker with the product code name, firmware, serial number, power rating, supported standards but also the drive capacity:

After removing the top sticker, we will note four NAND packages and a central controller:

The main controller is a Phison PS5021-E21T, a 4-channel controller built on TSMC’s 12nm process technology, using single-CPU architecture with built-in ARM Cortex-R5. The controller does only support DRAMless implementations, while in terms of NAND support, it can go with either 3D TLC or QLC:

The NAND packages do carry the TH58LKT2Z25BA8K code name and are of BiCS5 HDR type, TLC, 112-layer:
