The Optane Memory H10 is actually a QLC SSD and an optane memory placed on the single board, each one occupies its pcie3.0 x2 bus. There are no PCIe switch / mux / cache controller on the board, just two components glued together
By default the m.2 m key slot is configured to pcie3.0x4 mode so only one component will be visible. In my case it is the optane memory.
To switch the slot to pcie3.0 x2 +x2 mode, refer to Rockchip_Developer_Guide_PCIe Chapter 2.3.2 and change the dts accordingly. Please note the reset_gpio property for the pcie3x2 node should be set to GPIO1 B7 following board design.
I’m looking at using a 512GB Samsung 970EVO Plus SSD.
I can get a 512GB Optane for a similar price.
How does the performance compare ??
Some benchmarks have the Optane a fair bit slower !!
Of course I considered this, but optane has advantages that normal SSDs don’t have, like incredibly low latency. Anyway, I don’t think I need to explain why I want to use something that should work out of the box.
I literally booted from that drive with an OS that is not even officially supported, and that was 3 months ago.
I really don’t know what is the problem with yours that causing the nvme driver not recognizing it as a drive.
Mine has a model number of MEMPEK1J016GA, which has a label that appears to be a retail drive. (It’s the M10 optane drive). Yours appears to be an OEM drive. But there should not be much difference unless the OEM firmware is working weirdly.
I will try this at home, but from what I remember there isn’t anything that starts with nvme in /dev/. It would show up in lsblk too I suppose. But there is nothing there at all.
@gnattu have you ever tried your optane in a USB NVME enclosure? Does any system detect the drive when it’s in one?
