The newly released KIOXIA EXCERIA PRO G2 SSD (Kioxia VE10 solid‑state drive) hasn’t been tested by anyone online yet.
Product Brief. Specifications can be seen on the official website: EXCERIA PRO G2 - NVMe™ SSD | KIOXIA - Europe (English)

I bought a 4 TB capacity, PCIe 5.0 x4, TLC NAND.
Purchased on JD for ¥2999 (original price ¥3299, with a ¥300 coupon that appeared once).
Considering the rise in storage prices, and Silicon Motion CEO says there won’t be PCIe 6.0 drives for PCs before 2030:
Wallace C. Kou: For consumer? You will not see any PCIe Gen6 [solutions] until 2030.
Although I don’t have a computer with a PCIe 5.0 interface, this is the cheapest PCIe 5.0 drive on the market, even cheaper than some PCIe 4.0 drives, and should remain competitive for many years.

The controller is SM2508, this controller is used in domestic brands BWIN (by Bawei)/Acer Predator, Jiang Bolong/Lexar, and in almost all flagship models of international brands such as WD SN8100, Micron Crucial T710. It is built on TSMC 6 nm, offering excellent energy efficiency.
Given that this is Kioxia, I was surprised by this controller; I originally expected Kioxia to use its affiliated Phison E28, as Kioxia previously used Phison controllers almost exclusively.
It uses a single‑sided NAND design. There are two chips, each 2 TB, totaling 4 TB.
The NAND density is very high, likely using BiCS v8 2XX‑layer.
The DDR cache comes from SK Hynix.
I originally wanted to use flashid to view chip information, but the SMI nvme flash id driver reported an error.
According to the silkscreen, the SK Hynix LPDDR4X memory chip information is as follows:
| Part No | Density | Voltage (VDD/VDD2/VDDQ) | Speed | Package | Product Status |
|---|---|---|---|---|---|
| H9HCNNNCPMMLXR-NEE | 32 Gb (4 GB) | 1.8 V / 1.1 V / 0.6 V | 4266 Mbps | 200‑Ball | MP |
No results were found for NAND chips with silkscreen starting with TH58LKT.
The new drive is unformatted; SMART shows the following information:
Power‑on hours: 0, power cycles: 3, reads: 4.6 MB, writes: 0.
Power consumption has 5 levels, with a minimum idle power of 0.005 W and a maximum power of 10 W.

I don’t have a PCIe 5.0 platform, so I could only test on a PCIe 4.0 X570 platform.
Formatted the disk to ext4, and below are the test results using KDiskMark:

The default factory LBA size is 512; changing it to 4096 and testing again makes almost no difference.

The difference is minimal, indicating that changing it is unnecessary.
On Windows, I used TxBench for a RAW full‑disk write test; based on the CSV log, I plotted it with pyplot as follows:
Total time: 20 minutes 11 seconds.
At 1 minute 53 seconds, the curve drops sharply, indicating that the simulated SLC cache was exhausted, having written a total of 799175081984/1024**3=744.289794921875 GB of data.
Overall write speed:
Average: 3222.55 MB/s
Maximum: 6728.33 MB/s
Minimum: 1909.07 MB/s
Standard deviation (std dev): 1156.98 MB/s
If we look only at the middle portion:
Average: 2852.64 MB/s
Maximum: 3432.20 MB/s
Minimum: 1909.07 MB/s
Standard deviation: 254.04 MB/s
Because it is connected via a PCIe 4.0 interface, the early part of this test can only reach the PCIe 4.0 x4 limit of 7 GB/s; on a PCIe 5.0 platform it should be 14 GB/s. However, the middle portion’s speed still provides some reference value.
During the test, I used the SMART monitoring tool to check the drive temperature; it started at 33 °C and fluctuated around 78 °C during continuous writing. Considering there was no cooling (metal jacket/fan), this behavior aligns with the consistently good expectations for an SSD with an SM2508 controller.
