He is using an Samsung PM961
I did see on his lspci output it was reported as
"Subsystem: Samsung Electronics Co Ltd NVMe SSD Controller SM961/PM961", but pfeerick 960 EVO output is identical.

My limited insight to Samsung 960 NVMe devices indicates SM961 and PM961 devices were released to OEMs early in 2016. And Samsung later released EVO and PRO versions for the general public. However, as per Anandtech there are differences in the NAND chips which is what I expect explains the difference in iozone numbers from ayufan and pfeerick?

If the table at Anandtech is accurate then actual PM961 devices should be the slowest of the lot.

I remember, that Ayufan postet that he has an 960 Pro. But that is only from my memory, I can be wrong too. Waiting for Ayufan...
Sorry for any mistakes. English is not my native language

1. RP64 v2.0 / PCIe NVMe as root / sd-card as boot / 2,5 Zoll HDD 1TB (USB3) using as Webserver .... (Kernel 4.4.167-1140-rockchip-ayufan-g6f266fb5d677)
2. RP64 v2.1 / PCIe SATA Marvell 88SE9230 Chipsatz / sd-card / 2 * 2,5 Zoll 2TB HDD (raid1) / using as NAS / Kernel 5.0.0-1101-ayufan-g41eeb7cd789e
3. RP64 v2.1 / testing.....testing....testing


I do have 960Pro but in my PC. For RockPro64 I use separate NVMe drive with SM961 (This is on sticker).

Is it possible to switch system root "\" to PCIe NVMe SSD?
Boot directly from PCIe NVMe SSD?

Hopefully someone can figure it out how to do it.

I managed to get a used 128GB SM961 for a bargain price: came with some no-name PCIe adapter and worked first time:

/ssd$ sudo iozone -e -I -a -s 100M -r 4k -r 16k -r 512k -r 1024k -r 16384k -i 0 -i 1 -i 2
