PCI-E X4 to M.2/NGFF NVMe SSD - support? - AndyOfLinux - 08-03-2018
I have the PCI-E X4 to M.2/NGFF NVMe SSD card and wondered what type of M.2 drives people may be using? Also wondering if this card and M.2 drives (like the Samsung 970 PRO 512GB - NVMe PCIe M.2 2280 SSD) are supported under (ayufan) Ubuntu Bionic? Thanks for any info...

I use bionic-minimal-rockpro64-0.7.9-1067-arm64.img.xz and tested

- Samsung 970 PRO m.2 512 GB

I've hit a wall with attempting to get lscpi giving any output & the PCI-E slot working. Anyone know of a fix for this?

Which version of the board do you have?
RE: PCI-E X4 to M.2/NGFF NVMe SSD - support? - CrimsonKnight13 - 08-05-2018
Revision 2.1
RE: PCI-E X4 to M.2/NGFF NVMe SSD - support? - Bullet64 - 08-05-2018
Forget to ask.
Which Image do you use?
Which pcie card do you use?
Both cards from pine64 works fine with bionic-minimal-rockpro64-0.7.9-1067-arm64.img.xz and v2.1

Thanks for the responses with great info! I installed a Samsung 970 EVO 500GB - NVMe PCIe M.2 2280 SSD, using board v2.1 with bionic-lxde-rockpro64-0.7.9-1067-arm64. Works great
but hopefully we'll get more performance in the future with newer firmware &/or OS releases?With my ROCKPro64 and Samsung 970 EVO:
Code:
sudo hdparm -tT --direct /dev/nvme0n1
/dev/nvme0n1:
Timing O_DIRECT cached reads: 1110 MB in 2.00 seconds = 555.17 MB/sec
Timing O_DIRECT disk reads: 1668 MB in 3.00 seconds = 555.50 MB/secWith my Intel i5 NUC and Samsung 950 PRO:
Code:
sudo hdparm -tT --direct /dev/nvme0n1
/dev/nvme0n1:
Timing O_DIRECT cached reads: 1978 MB in 2.00 seconds = 989.90 MB/sec
Timing O_DIRECT disk reads: 3210 MB in 3.00 seconds = 1069.41 MB/secRE: PCI-E X4 to M.2/NGFF NVMe SSD - support? - Bullet64 - 08-06-2018
Are you using mainline kernel? Atm, mainline kernel is faster.
