Good cables matter.
I have some really really nice looking thick and heavy duty cables, yet crap. You can never know. Like I said in an earlier post, some cables are basically designed for power. I've had good luck with short USB-3 to SATA cables for RPI[3/4/5] and my ubuntu desktop. My USB drive enclosure has a USB-3 to USB-C cable that works, but I thought my aforementioned really really nice looking cable would be better. It wasn't. The zpool I created would always get checksum errors and scrub would always find more. Changed the cable, viola! worked like a champ. I'm really quite surprised that the cables can be that bad. Oddly enough, the RPI seems to do better with USB than my desktop. > > > In this case I'm using those nice thick cables that came with the little > portable WD drives I am using, short USB-C to USB-C, including using the > converters that came with them to plug into an old type USB jack on the > powered hub.

Personally, I will never use linux raid again. It's not that it is a bad technology, but it lacks data integrity features you need. In the linux environment today, I can't think of a better storage system than ZFS, especially if you value data integrity. _______________________________________________ Discuss mailing list Discuss@driftwood.blu.org https://driftwood.blu.org/mailman/listinfo/discuss
