last night, I fixed my thermal camera.
There was a hole in center of the nvme, now I can confirm it was heat sink.
heat sink is slight cooler than surroundings.
Probably not. Metal objects reflect IR and often appear on thermal cameras colder than they actually are.
I used to work in radiator factory, and chrome coated models always appeared as completely cold in thermal imaging (or even reflected my heat back to a camera!). We sticked pieces of colored tape on them to measure their performance in a few points.

There are reflections on M1's HDMI, USB ports. even QC sticker is +10C higher.
I wonder is there any none-contact method to measure temperature on shinny surface.

Oh tape !! that's great idea.

Code: Select all

odroid@server:~$ zpool iostat Test 3600
              capacity     operations     bandwidth 
pool        alloc   free   read  write   read  write
----------  -----  -----  -----  -----  -----  -----
Test        44.6T  20.9T     43    555  1.10M  91.7M
Test        44.6T  20.9T  4.30K      0   112M      0
Test        44.6T  20.9T  4.33K      0   113M      0
pool read is over +200MB/s, sha256sum, md5sum are slower than expected.
md5sum can calculate at 110MB/s. sha256sum was 69MB/s.

I should diff directly with nfs mount.

finished diff largest directory, about 30TB.
I made per file md5sum list, 71746 lines of hash + filepath.
didn't used nfs, because I need network disconnection.

result ? no misshashed file. all 71746 files had same md5sum result.
finally, I got 3 copies of my data. :D

I think M1 an this controller works very well and reliable.
there was only few kernel message about ethernet disconnection, caused by router update and unpluging to test odroid C4.

I need full speed 2.5Gbps ethernet. :lol:

Other than an ATX supply or maybe a PicoPSU, anyone have creative suggestions on how to power 5 SSDs as opposed to 5 spinning disks?

2.5" SATA SSD will not consume power over 8Watt probably.
Therefore, 5V/8A or 5V/10A PSU with a SATA power splitter cables might be sufficient.

Glad to hear that JMB575 chipset based SATA Multiplier is working fine with the M1's native SATA port.
Thank you for sharing the good news.

little bit tired of repositioning my JMB585.

I sent my M1 and sata controller to hardkernel service team.
but they could not test it. because it didn't worked at all with default linux image.
I could not ask them to recompile kernel and test it on other M1. :lol:

service team called me many times to verify problems, and kinda nice.

I'll test nvme ssd with 5 disk array with sata mulipler.
this setup can use ssd as zfs cache device.
